What is an APC Smart-UPS RT replacement battery?

Smart-UPS SRT (and the older Smart-UPS RT) use sealed lead-acid (SLA) cartridges in a defined APCRBC configuration. Smart-UPS Ultra (SRTL) uses a lithium-ion (LiFePO₄) pack rated for 10-year service life. Both are hot-swappable — the UPS continues to protect the load during the swap. SRT SLA cartridges typically need replacement every 3–5 years in 20–25 °C ambient; SRTL lithium packs are rated for 10 years.

UPSPLUSBATTERY.CA stocks the full SRT cartridge range — both genuine APC and compatible aftermarket SLA. SRTL lithium packs are factory APC only (BMS firmware is matched to the UPS at manufacture). For Smart-UPS line-interactive cartridges, see APC Smart-UPS replacement batteries. For Back-UPS, see APC Back-UPS replacement batteries. Full APC battery catalog at APC RBC batteries.

How to identify the right cartridge

Method 1: front-panel LCD

About → Battery on the LCD displays the APCRBC or lithium-pack part number. Most reliable method on SRT and SRTL.

Method 2: unit label

Side or rear of the chassis lists the model number and compatible cartridge.

Method 3: existing cartridge

Open the front bezel — cartridge label lists cell count, voltage, and Ah. SLA cartridges only; lithium packs are sealed.

Genuine APC vs compatible aftermarket

SRT SLA cartridges: both options stocked. SRTL lithium-ion: factory APC only.

Genuine APC SLA: OEM cartridge with factory tested-date sticker, 2-year APC battery warranty, guaranteed compatibility with PowerChute and AP9641 runtime estimation. Required for in-warranty SRT.

Compatible aftermarket SLA: Identical form factor, connector, voltage stack — built from CSB, Yuasa, BB Battery, Panasonic cells. Typically 30–50 % less than genuine. 1-year UPSPLUSBATTERY warranty.

SRTL lithium pack (SRTL180RM2UBP): Factory APC only. Sealed LiFePO₄ pack with BMS firmware specific to the SRTL chassis. We do not stock aftermarket lithium replacements — chemistry, BMS, and safety certification require factory matching.

How long do SRT and SRTL batteries last?

SLA on SRT: APC rates 3–5 years in 20–25 °C ambient. Lithium-ion on SRTL: 10 years rated by APC, with 5-year factory battery warranty (USA and Canada). Replace promptly when PowerChute or front-panel flags battery. When to replace UPS battery.

How to replace

Every current SRT and SRTL is hot-swappable. Procedure:

Order the correct APCRBC or SRTL pack (verify against the unit label or LCD About menu).
Slide the front bezel off.
Disconnect the polarised battery connector.
Slide old cartridge / pack out, new one in.
Reconnect the connector until it clicks.
Replace the front bezel.
Reset install date via LCD: About → Battery → Reset install date.

Swap takes 5–10 minutes depending on chassis size. SRT 5–10 kVA cartridges are heavier; use the included handle straps. Read how to install UPS battery.

External battery packs (extended runtime)

SRT supports SRT48BP, SRT72BP, SRT96BP external battery packs depending on host chassis voltage. SRT5KRMXLT supports SRT192BP (192 V). Multiple packs stack for runtime extension. Connect via supplied bus cable, hot-pluggable on most models. SRTL supports SRTL5KRMBP2U external lithium pack — factory APC only.

Warranty and support

Genuine APC SLA: 2-year APC battery warranty. Compatible aftermarket SLA: 1-year UPSPLUSBATTERY full-replacement warranty. Factory SRTL lithium pack: 5-year APC battery warranty. Coordinated through our Canadian team. Shipped from our Canadian warehouse. Replies within 1 business day.

FAQ

SRT vs Smart-UPS Ultra battery?

SRT uses SLA APCRBC cartridges (3–5 yr life). SRTL uses sealed LiFePO₄ packs (10 yr rated, factory APC only). For long-deployment or hot ambient, SRTL pays back.

How do I know which APCRBC fits my SRT?

Check the front-panel LCD About menu, or the unit label. SRT1500 → APCRBC155, SRT2200 → APCRBC141, SRT3000 → APCRBC152, SRT5K/6K → APCRBC140, SRT8K/10K → APCRBC140 ×2.

Can I use aftermarket on SRTL?

No. SRTL lithium pack BMS firmware is matched to the chassis at manufacture. Only factory APC SRTL180RM2UBP and SRTL pack equivalents are supported.

External battery packs?

Yes — SRT supports SRT48BP / SRT72BP / SRT96BP / SRT192BP depending on chassis voltage. Multiple stack for runtime extension; hot-pluggable on most.

Hot-swap?

Yes on every current SRT and SRTL.

Battery warranty?

Genuine APC SLA: 2-yr APC. Aftermarket SLA: 1-yr UPSPLUSBATTERY. Factory SRTL lithium: 5-yr APC.

Disposal?

SLA cartridges: municipal hazardous-waste depot or Call2Recycle drop-off. Lithium packs: certified lithium-battery recycler — return to us with new cartridge purchase and we'll handle proper disposal.
