Data Center UPS Batteries —
Edge to enterprise replacement sets for Canadian IT

Factory-fresh replacement battery sets for the rack-mount and modular UPS plant that keeps Canadian MSPs, edge sites, small colos, and enterprise branch data closets online. Matched by chassis model code — Smart-UPS RT, Symmetra LX, Smart-UPS X, Eaton 9PX — shipped same-day from our Toronto warehouse, with bulk pricing on MSP fleet refreshes of 10 units or more and stocking-kit options for parts-inventory buyers.

The problem this industry has

Data center UPS battery procurement is harder than it looks

Four reasons MSPs, edge-site operators, and small-colo IT teams keep landing on the wrong cartridge, or waiting longer than they should to refresh a UPS plant that’s aging silently.

MSPs lose fleet visibility somewhere around client #5. A managed-services operator running 50 Smart-UPS RT units across a Toronto client base typically started with a clean inventory: client A has two SURT5000s installed Q2 2019, client B has three SURT10000s installed Q3 2019, etc. By client #15 the spreadsheet is stale; by client #30 nobody knows which battery is in which UPS until the alarm pings. That’s fine for the first few years — until the cohort starts failing in unison, the help-desk tickets stack up, and the MSP is suddenly ordering twos and threes from whichever distributor responds first. The unit economics on emergency parts pricing erase the margin the MSP planned on. A fleet-view inventory turns the same refresh into a single bulk PO at planned-buy pricing.

EOSL platforms are the parts-hunting problem. APC declared end-of-service-life on the original Symmetra PX 10/20/40 line, on the Galaxy 3500, on Powerware 9395 first-gen modules, and on a handful of older Smart-UPS RT vintages. The chassis still runs — the support contract no longer does. For sites that can’t justify the capex to replace the chassis outright, the question shifts to: who stocks the battery modules, where are they manufactured, and how recently? Generic distributor channels run thin on these SKUs because the OEM stopped pulling fresh inventory. Date-code matters more on EOSL platforms than on currently-supported lines — a 24-month shelf-aged cartridge in a Symmetra LX is half a usable lifecycle wasted.

Small-colo Smart-UPS RT lifecycle is invisible until it isn’t. A 20-cabinet colo running a redundant pair of Smart-UPS RT 10000 units in N+1 protecting the network core sees the UPS plant as background infrastructure. The unit hums, the runtime indicator reads fine, the SNMP card pings green. Battery aging is happening at the chemistry level, not at the BMS level — until one Tuesday morning when the primary RT alarm-fails its self-test, the secondary takes over, and the operator suddenly has to source 16 series-wired batteries to refresh the failed string. Same-day shipping from Toronto fills that gap; ordering from a US distributor on Net-30 with cross-border freight doesn’t.

The “is this still serviceable?” question stalls more refreshes than budget does. A 6-year-old Smart-UPS X 3000 in a comms closet at a regional branch office can be refreshed for the price of one cartridge — or replaced wholesale for 8× the cartridge price. The right decision depends on the chassis condition (capacitors, fan health, firmware support window), not on the battery alone. We don’t replace the chassis — we ship the battery — but every scenario below assumes the chassis is healthy enough to merit the refresh. If the chassis is past its serviceable life (typically year 8–10 for Smart-UPS-class hardware), the right move is a chassis replacement and a fresh battery set, not a battery alone.

This hub walks through three scenarios drawn from real Canadian MSP, hospital data closet, and branch-deployment procurement patterns — edge MSP fleet refresh, hospital Symmetra LX SYBTU1-PLP annual purchase, and Smart-UPS X extended-runtime branch deployment — with the specific replacement battery sets that fit each one, drawn live from our Toronto warehouse inventory. Plus a fourth Eaton 9PX section for IT teams running mixed-vendor environments.

Scenario № 1 — Edge MSP / Smart-UPS RT fleet

An MSP managing 50 Smart-UPS RT units finds out the cohort fails together

Setting — Managed-services provider, Greater Toronto, 50+ client sitesEquipment — APC Smart-UPS RT 5000VA / 10000VA fleetBattery age — 5 to 7 yearsScenario story

When an MSP rolls out the same Smart-UPS RT model across 30+ client racks in a single procurement window, the batteries reach end-of-life within a few quarters of each other — and the help-desk doesn’t see it coming until the third client calls in the same week

The setting

A managed-services provider headquartered in Greater Toronto runs the network-edge UPS plant for roughly 50 mid-market client sites — legal firms, accounting offices, small healthcare practices, and a couple of regional manufacturing clients. The MSP’s standard playbook in 2019–2020 was the Smart-UPS RT 5000VA (SURT5000RMXLT) for single-rack client deployments and the Smart-UPS RT 10000VA (SURT10000RMXLT) for the larger network closets with two-rack redundancy. Both are double-conversion online platforms with replaceable battery cartridges — the right choice for billing the client a per-month managed-services line that covers proactive replacement.

The trigger

The MSP’s NOC started seeing a familiar SNMP trap in early Q1 of the sixth year after the rollout: a Smart-UPS RT 5000 unit at a Mississauga legal-firm client reporting Battery Replacement Needed during a weekly self-test. The on-call tech raised a ticket, ordered a cartridge from a US distributor, drove it out the next week, replaced the battery, closed the ticket. Routine.

Then it happened twice the following week. Then four times the week after. By the end of the quarter the MSP’s ops manager had logged 11 battery-replacement tickets across 9 different client sites — all running Smart-UPS RT units from the 2019–2020 rollout window. The cartridge orders were going to three different distributors at three different price points, with three different lead times. The total cartridge spend for the quarter was 60% over budget. The ops manager went back to the deployment records and counted: 36 Smart-UPS RT units across 24 client sites, all installed within an 18-month window. Roughly two-thirds of the fleet was past the 5-year battery service horizon. The wave had just started.

What happens without a cohort plan

Without a fleet-view cohort plan, this becomes 36 separate emergency orders over the following 9–12 months. Each unit’s self-test eventually trips the Replace Battery alert, raises an SNMP trap, drives a help-desk ticket, and triggers a one-off cartridge purchase. The MSP pays retail per unit on whichever distributor has stock that week, eats the dispatch cost, and ends up with 36 different invoices across multiple vendors. The cost of running an MSP at retail-emergency pricing on parts is the difference between a profitable services line and a break-even one.

It also stretches the at-risk window. The Smart-UPS RT cohort that’s already aged past its service horizon keeps aging while waiting for individual emergency replacements. Client #25 of 36 may experience a battery-discharge event during a real utility outage before client #25’s ticket is even raised. The MSP’s SLA exposure here isn’t theoretical — it’s the difference between a managed-services renewal at the next quarter and a client churn driven by an avoidable outage.

The recommendation

For an MSP with a known cohort, the right move is a single bulk purchase of all 36 cartridges, scheduled across an 8–10 week field-replacement window managed by the MSP’s field-engineering team. Bulk pricing applies to orders of 5+ identical Smart-UPS RT cartridges from our Toronto warehouse. Cartridges ship from a tight manufacturing date-code window where inventory allows, which simplifies the post-refresh evidence record (useful if any of the MSP’s clients have downstream compliance reporting). A single project-level PO replaces 36 emergency orders. The MSP’s ops manager gets a single line on the project ledger; the help-desk gets predictable scheduled tickets instead of a wave of unplanned ones; the at-risk window collapses from 9–12 months down to 8–10 weeks.

What this looks like in the cart

For the MSP’s SURT5000RMXLT-class fleet (single-rack clients), the matched cartridge is the SURT5000RMXLT Battery Replacement Kit at $449.99 CAD. For SURTD5000RMXLT-class units (the dual-conversion variant common in network-rack deployments), it’s the SURTD5000RMXLT Replacement Battery Kit at $499.99. For SURT6000XLI-class units (a tower variant used in some early MSP single-rack deployments), it’s the SURT6000XLI Battery at $499.99. For SURT10000RMXLT-class units (two-rack network closets), it’s the SURT10000RMXLT Battery Set at $905.76. Same-day shipping from Toronto on orders placed before 1:00 PM Eastern, 1–3 business days to most Ontario destinations, MSP parts-kit pricing on the project quote.

Scenario № 2 — Hospital data closet Symmetra LX refresh

The biomedical engineering buyer placing a SYBTU1-PLP annual stocking order

Setting — Mid-sized Canadian hospital, biomedical engineering procurementEquipment — APC Symmetra LX with modular battery cabinetBattery age — rolling refresh, 3 to 5 year service windowScenario story

When a hospital’s biomedical procurement office places its annual Symmetra LX battery order, they’re not refreshing one cartridge — they’re re-stocking modular battery slots across a multi-cabinet plant, and the date code on each SYBTU1-PLP module matters more than the unit price does

The setting

A mid-sized Canadian hospital runs the data closet and core network infrastructure off an APC Symmetra LX platform — the modular online double-conversion product line that’s common in HQ-tier banking, mid-market hospital data closets, and any deployment where the IT plant needs the N+1 redundancy of a hot-swap battery architecture but doesn’t need the full footprint of a Symmetra PX. The same architecture shows up in HQ-tier banking branches; the buyer persona and procurement pattern are nearly identical between hospital biomed and bank IT-procurement teams.

The hospital’s Symmetra LX deployment includes the chassis, the power modules, the intelligence module (SYMIM5-class), and a modular battery cabinet populated with SYBTU1-PLP battery modules wired in a series-string configuration. The platform’s value is the modular battery architecture: instead of replacing a single large series-wired battery set when one cell fails (the Smart-UPS RT pattern), the operator hot-swaps individual SYBTU1-PLP modules without taking the UPS offline. The chassis stays up, the network stays up, the surgical-scheduling workstation upstream of the data closet stays up. That’s the whole reason the hospital bought Symmetra LX in the first place.

The trigger

Biomedical engineering at this hospital runs an annual procurement cycle in Q4 for the upcoming fiscal year. Inventory clerk pulls the Symmetra LX battery-module install records, identifies which modules will hit the 4-year service horizon in the upcoming year, adds a safety stocking buffer, and writes a single PO to the supplier with the agreed-on annual stocking quantity. That’s the workflow. It’s the same workflow used for IV pumps, infusion sets, and dozens of other consumable-but-critical inventory categories.

The procurement question isn’t “will this module fit our Symmetra LX?” (the answer is yes, the SYBTU1-PLP is the standard Symmetra LX battery module). The procurement question is: where is the supplier getting their inventory from, and how recently was it manufactured?

The chemistry argument for date-code discipline

VRLA AGM batteries begin losing capacity from the day they leave the manufacturing line, even unused. A SYBTU1-PLP module sitting on a US distributor shelf for 18 months in a warm warehouse arrives with 70–80% of nominal capacity already gone — before it’s ever installed in the hospital’s Symmetra LX cabinet. For a hospital running a 4-year refresh cadence on modules, that’s 30–40% of usable service life lost to shelf-aging before the chassis ever sees the cartridge. On an annual stocking buy of 10–15 modules, the cost differential between a fresh-from-factory cohort and a shelf-aged distributor cohort is roughly 1.5 service years — a procurement-level concern, not a chemistry-bench curiosity.

Our Toronto warehouse rotates aggressively against the manufacturer date code; SYBTU1-PLP modules shipped from inventory are typically <6 months from manufacturing. For annual stocking buys, we can quote against a single date-code window where the inventory allows, simplifying the post-refresh maintenance record.

The hot-swap procedure note

Symmetra LX SYBTU1-PLP modules are designed for hot-swap operation — the chassis stays in inverter mode while the operator removes one module and inserts a replacement. The procedure is documented in the APC product manual; the practical operational rule is: hot-swap one module at a time, wait for the BMS to register and balance the new module’s charge state, then move to the next. Swapping multiple modules simultaneously creates a transient impedance imbalance across the active string that can trip the chassis into bypass mode. For hospital data-closet ops, the safe pattern is a single-module-per-pass approach with a 5–10 minute wait between modules; for ops teams with engineering coverage, a faster cadence is feasible but adds operational risk to the procedure.

The intelligence module (SYMIM5-class for current Symmetra LX deployments) monitors and balances the active battery string; if your hospital’s intelligence module is itself aged or showing intermittent fault conditions, the SYMIM5 is also available as a refurbished replacement — useful for procurement teams refreshing the whole Symmetra LX maintenance plant in a single buy.

The recommendation

For an annual hospital biomed procurement, the right pattern is a single PO at year-start with quantity sized to the projected refresh count plus a stocking buffer of 2–3 modules for unplanned mid-year failures. We hold SYBTU1-PLP inventory year-round at 100 units in stock from our Toronto warehouse, with bulk pricing on qty ≥ 5 and procurement-friendly documentation (Canadian-format invoice with HST breakout, packing list line-matched to the requisition, factory-fresh date codes on each module). Add the SYMIM5 intelligence module to the order if any of the deployment’s intelligence units are themselves showing fault conditions; refurbished modules carry a one-year warranty equivalent to the new-product warranty for the battery cartridges. PO acceptance is standard for hospital procurement systems.

Scenario № 3 — Smart-UPS X 2000 / 3000 extended runtime branch

When a branch deployment needs extended runtime, not just bridge time

Setting — MSP / small-colo branch deployment, mixed Ontario sitesEquipment — APC Smart-UPS X 2000VA / 3000VABattery age — 4 to 6 yearsScenario story

The Smart-UPS X line was designed for the branch deployment where the operator needs 30–60 minutes of runtime — not 5 minutes — and the battery selection follows from that runtime requirement, not from the chassis VA rating alone

The setting

An MSP’s branch deployment playbook for clients running a small core-network rack in a remote branch office (a brokerage’s satellite trading desk, a regional law-firm branch, a small healthcare practice’s after-hours coverage stack) often uses the Smart-UPS X 2000VA / 3000VA line. The X-series chassis is engineered for the extended-runtime use case: where Smart-UPS C and Smart-UPS SMT chassis target 5–15 minute bridge runtimes against a utility outage, the X chassis pairs an internal battery set with optional External Battery Modules (EBMs) to deliver 30–90+ minutes at typical branch loads.

The why: in a remote branch with no on-site IT staff, a 5-minute bridge isn’t enough. The branch needs runtime long enough for the WAN link to recover (which may include carrier-side outages lasting 15–30 minutes), the network gear to gracefully sequence through restart, and any in-flight transactions to commit before a graceful shutdown if the outage extends. The extended-runtime SMX deployment buys that operational window.

The trigger

A 5-year-old Smart-UPS X 3000 SMX3000RMLV2U in a regional branch office sees its first Replace Battery alarm during a routine self-test. The runtime indicator drops from 47 minutes nameplate to 14 minutes actual. The branch’s IT contractor opens a ticket with the MSP; the MSP’s ops manager reviews the deployment record and notes the unit was installed in 2020 with an SMX120RMBP2U external battery module attached for extended runtime. The refresh isn’t one cartridge — it’s the SMX internal battery PLUS the SMX120RMBP2U battery module, replaced as a coordinated string refresh to preserve the runtime-engineering profile the original deployment was sized around.

The runtime calculation embedded in the buy decision

An SMX3000RMLV2U with no EBM nominally runs ~10 minutes at 50% load (around 1,500W) on a fresh internal battery set. Add one SMX120RMBP2U external battery module and the same load runs roughly 30–35 minutes. Add a second SMX120RMBP2U and you’re in the 55–70 minute range. The math isn’t linear because charge-balance overhead grows with string size, but the rule of thumb is: each EBM roughly triples the standalone chassis runtime at 50% load. The branch deployment’s original sizing decision picks an EBM count to match the expected outage profile; the refresh decision needs to preserve that count, not just refresh the internal battery and leave the EBM running on aged cells.

The cohort logic from Scenario #1 applies here too: an internal Smart-UPS X battery set and its paired EBM(s) installed on the same date will age at roughly the same rate. Refreshing one without the other creates an impedance gradient between fresh and aged cells that imbalances charge current across the full string. The right pattern: refresh internal and EBM together, in a single ordering window, with cartridges from the same manufacturing date code where inventory allows.

The recommendation

For an SMX2200RMLV2U / SMX3000RMLV2U deployment, refresh both the internal battery set and the paired SMX120RMBP2U external battery modules in a single procurement window. Pricing from our Toronto warehouse: $283.05 CAD per internal battery set for the SMX2200RMLV2U-class chassis, $283.05 for the SMX3000RMLV2U-class chassis, $283.05 for the SMX2000RMLV2UNC variant, and $283.05 for the SMX120RMBP2U external battery module. (Pricing is consistent across the SMX-series sets — chassis-internal vs. EBM-external is a form-factor distinction, not a capacity one.) For an MSP managing multiple branch deployments, the bulk-order pattern is the same as in Scenario #1: gather the chassis model codes across your client base, get a single project quote, refresh the cohort across an 8–10 week window. Same-day shipping from Toronto on orders placed before 1:00 PM Eastern.

Engineering substance

Battery chemistry, hot-swap procedure, and the engineering rules that govern modular battery cabinets

Five things worth knowing before you order a replacement — especially for Symmetra LX modular cabinets and Smart-UPS RT N+1 deployments where the wrong refresh pattern creates more failure than the original fault did.

VRLA AGM is still the dominant chemistry — Lithium-Ion is emerging

Nearly every Smart-UPS RT, Symmetra LX, Smart-UPS X, and Eaton 9PX battery cartridge in the catalog ships in VRLA AGM chemistry. It’s the chemistry the UPS chassis was designed around: known charging profile, predictable float-voltage behaviour, BMS firmware tuned to its service curve. Lithium-Ion options are emerging (APC SRTL line, Eaton 9PX-L Lithium variant in the catalog) with 10–15 year calendar life, wider thermal tolerance, and the ability to deep-cycle without accelerated degradation — at a 2–2.5× capex premium and only on chassis specifically engineered for Li-Ion. For a data center refresh fleet built on existing VRLA chassis, the rule is: replace VRLA with VRLA. Mixing chemistries on an existing chassis isn’t supported by the BMS firmware and creates fault conditions on every self-test cycle.

Voltage matching — never mix old and new in a series string

Smart-UPS RT and Smart-UPS X battery sets are configured as series strings — multiple 12V batteries wired in series to reach the UPS’s DC bus voltage (typically 96V or 192V depending on chassis). A SURT10000RMXLT runs 16 batteries in series; a SURT5000RMXLT runs 8. Mixing fresh batteries with thermally-aged batteries in the same string creates an impedance gradient that imbalances charge current and accelerates failure across the entire string. A partial swap on a 16-battery SURT10000 string turns the unit into a self-destructing pack within months. The universal rule for non-modular series-wired chassis: full string refresh, not partial. The Smart-UPS X EBM rule is the same: refresh internal + EBM together when both are aged on the same cohort.

Modular battery cabinets play by different rules — hot-swap one at a time

The Symmetra LX SYBTU1-PLP architecture inverts the series-string rule. Modular battery cabinets are designed to tolerate per-module refresh while the chassis stays in inverter mode. The intelligence module monitors each module’s charge state, balances current across the active string, and brings new modules online after a short equalization window. The operational rule for hot-swap: one module at a time, wait 5–10 minutes between swaps for BMS equalization, swap modules in physical sequence around the cabinet to maintain mechanical balance. Swapping 3–4 modules simultaneously creates a transient that can trip the chassis into bypass — the procedure exists for a reason. For ops teams with engineering coverage, faster swap cadences are feasible; for after-hours runs in unmanned data closets, default to the conservative sequence.

Temperature — the single biggest TCO lever on rack-mount UPS plants

VRLA service life halves for every 8–10°C of sustained ambient above 25°C (Arrhenius). A network closet running at 28°C cuts effective battery life by ~30% vs a 25°C ambient. A small-colo cabinet hall running at 27–28°C in summer integrates to a service curve significantly worse than a properly-cooled enterprise data hall. The cheapest TCO improvement on any rack-mount UPS plant is room ambient management — cabinet airflow, hot-aisle/cold-aisle hygiene where applicable, and an SNMP temperature trap that surfaces ambient drift months before it halves the next battery’s life. For MSPs running multi-client deployments, a $200 per-site thermistor + alarm package pays back inside one avoided emergency cartridge order.

Why “factory-fresh” matters more for EOSL platforms — date code is the procurement signal

VRLA batteries begin losing capacity from the day they leave the manufacturing line, even unused. A cartridge sitting on a US distributor shelf for 18–24 months in a warm warehouse arrives with 60–75% of nominal capacity already lost — before it’s ever installed in a Symmetra LX cabinet or a Smart-UPS RT chassis. For EOSL platforms (Galaxy 3500, Symmetra PX original-gen, Powerware 9395 first-gen) this matters more than on currently-supported lines because the OEM stopped pulling fresh inventory from the manufacturers years ago, and the channel inventory available through generic distributors is aged. Our Toronto warehouse rotates aggressively against the manufacturer date code; units shipped from inventory are typically <6 months from manufacturing. The practical difference between a fresh-from-factory cartridge and a shelf-aged unit is 12–18 months of additional in-service life. For an MSP’s fleet refresh on aging chassis, that’s 25–30% of total service life on the table. Ask for the date code window on any large procurement before signing the PO.

FAQ

Questions data center and IT buyers actually ask

What’s the difference between SURT5000 and SURT5000RMXLT batteries?
The SURT5000-family naming on the chassis side reflects multiple chassis variants in the same VA tier: SURT5000XLI (tower, international 230V), SURT5000RMXLI (rack-mount 230V), SURT5000XLT (tower 208V North America), and SURT5000RMXLT (rack-mount 208V North America). The battery cartridges are physically and electrically matched to the chassis variant, not interchangeable across the whole 5kVA tier. For the rack-mount 208V North American variant (SURT5000RMXLT), the matched cartridge is the SURT5000RMXLT Battery Replacement Kit at $449.99 CAD. For the dual-conversion variant SURTD5000RMXLT, it’s the SURTD5000RMXLT kit at $499.99. Confirm the rack-mount-vs-tower form factor and the 208V-vs-230V voltage code on the rear-panel chassis label before ordering.
Can I hot-swap a Symmetra LX battery module?
Yes — that’s the whole architectural point of the Symmetra LX. SYBTU1-PLP battery modules are designed for hot-swap operation while the chassis stays in inverter mode. The procedure: remove one module, wait for the intelligence module (SYMIM5-class) to register the missing module and rebalance current across the remaining active string, insert the replacement module, wait 5–10 minutes for the new module to equalize against the active string’s charge state, then move to the next module. Swapping multiple modules simultaneously can trip the chassis into bypass mode — the documented one-at-a-time procedure exists for a reason.
Are these batteries OEM or compatible-grade?
The cartridges we ship are manufacturer-spec OEM-equivalent in VRLA AGM chemistry — matched to the original APC, Eaton, or other-vendor spec for the chassis they fit. They are not generic substitutes. For higher-tier platforms (Symmetra LX, Smart-UPS RT), warranty terms typically require professional installation by a manufacturer-authorized servicer. For procurement contexts that require a specific OEM-only branded cartridge, contact us with the spec language and we’ll confirm match before quote.
Do you stock batteries for EOSL Galaxy 3500 or Symmetra PX first-gen units?
Yes — we hold inventory for several EOSL platforms that aren’t actively listed on the storefront, including original-gen Symmetra PX cartridges, certain Galaxy 3500 battery cabinet modules, and Powerware 9395 first-gen modules. The catalog reflects what’s commonly purchased through self-service, but the Toronto warehouse stocks deeper than the listed catalog. Email us the chassis model code and the battery part number and we’ll quote the matched cartridge within one business day. For EOSL platforms specifically, factory-fresh date codes matter more than on currently-supported lines — ask for the date-code window on your quote.
What’s the lead time on 50+ unit MSP orders?
For MSP fleet refresh orders of 50+ cartridges across mixed Smart-UPS RT / Smart-UPS X / Symmetra LX SKUs, the typical lead time is 5–10 business days from quote acceptance. Most APC Smart-UPS RT and Smart-UPS X cartridges are stocked at 100 units in Toronto and ship from current inventory within 1–2 days. Symmetra LX SYBTU1-PLP is also stocked at 100. For very large orders (200+ identical cartridges) or for EOSL platform cartridges where we may need to coordinate a fresh manufacturer pull, lead times can extend to 3–4 weeks. For MSPs scheduling a coordinated multi-week field refresh, we can split the shipment into 2–3 LTL drops to align with your field-engineering team’s install cadence.
How does the PO procurement workflow work?
For MSP and IT procurement teams, the standard workflow: email info@upsplusbattery.com with the chassis model codes, quantities per SKU, shipping destination(s), and the procurement contact at your organization. We return a written quote with Net-30 terms by the next business day. Quotes include a project line item identifying the cartridges as MSP fleet-refresh replacements, Canadian-format invoice with HST breakout, and the agreed-on date-code window where inventory allows. We accept POs through standard MSP procurement portals and government/Crown corporation systems. Reserved-inventory pricing available for 200+ cartridges/year stocking arrangements.
Same-day shipping — how does that work for an MSP’s scheduled refresh?
Orders placed before 1:00 PM Eastern on a business day ship the same day from our Toronto warehouse via Canada Post Expedited Parcel or Purolator Ground. For an MSP scheduling a coordinated field refresh across 30+ client sites, the typical workflow isn’t same-day — it’s a coordinated LTL freight drop sized to the project timeline, splittable across 2–3 drops across an 8–10 week field-replacement window. For emergency one-off replacements, email us directly; we can usually arrange Saturday delivery. Ontario/Quebec major cities: next-business-day. Prairies: 2–3 business days. BC: 3 business days. Atlantic Canada: 2–4 business days. Northern Canada: 5–7 business days.
What’s the warranty on data center cartridges?
Standard warranty on the battery cartridge is one year from invoice date against manufacturing defects and premature failure under normal operating conditions (25°C nominal ambient, standard UPS float duty in a properly-cooled rack environment). The warranty covers manufacturing defects only — not accelerated end-of-life from thermal stress, not physical damage from improper installation, and not normal end-of-life wearout. For SYMIM5 and other refurbished APC parts, the same one-year warranty applies, covering defects in the refurbished module. For MSP fleet refresh orders, extended warranty terms are available on request as part of the project quote. Confirmed defective cartridges are replaced at no cost; email us with the invoice number, chassis model code, and failure description and we respond within one business day.
