Tripp Lite BC850RNC Battery Replacement: What Battery Type It Uses and Where to Order in Canada

If you're searching for the right replacement battery for the Tripp Lite BC850RNC, you're not alone. We hear from IT managers, office staff, and tech teams every week who need a fast, mistake-proof answer. The biggest risk here is ordering a battery that doesn't fit, doesn't match the specs, or just flat-out won't restore your UPS to service. Let's make sure that doesn't happen to you.

Which Battery Fits the Tripp Lite BC850RNC—and Where to Buy It in Canada?

The Tripp Lite BC850RNC uses a single 12V sealed lead-acid (VRLA) battery. It's user-replaceable through the rear battery door—no special tools. Unlike APC models that use proprietary cartridges (like RBC packs), Tripp Lite's solution is straightforward: you swap the internal 12V block battery with your hands.

The product you want is the Tripp Lite BC900Lan (Replacement) Battery. This battery meets the electrical and physical specs for the BC850RNC, and it’s in stock at UPSPlusBattery (ships Canada-wide, no customs, headquartered in Montreal).

Before You Buy: Quick Compatibility Checklist

Don’t guess. Here’s how you confirm you’re getting the right battery for the BC850RNC. Snap a photo of your UPS label and the battery inside before ordering if you’re not sure.

Check What to Look For Why It Matters
UPS model BC850RNC (on bottom or back label) Confirms you’re buying for the 850VA/450W standby UPS
Battery code/pack label 12V, 7–9Ah VRLA (see old battery casing) Voltage must match; Ah (capacity) can equal or be higher if battery compartment fits
Number of batteries 1 battery inside (not a pack) Ordering more or less is a common mistake
Voltage & Ah 12V, 7–9Ah rating Using 24V or a lower/higher Ah block risks malfunction
Connector type Standard UPS F2 blade terminals Re-uses your existing wiring—no adapters needed

Short on time?

  • If your UPS has a different model code, double-check or call us: 438-881-3363
  • If you see swelling, leaks, or can’t read the battery label, get advice before you order

Installation Reality Check: What Should You Expect?

You’ll need to fully power down the BC850RNC—this model is not hot-swappable. Here’s what your team will actually do:

  • Time required: 10 minutes or less
  • Tools: None (battery compartment door is tool-free)
  • How:
    • Unplug the UPS from wall and attached equipment. Wait 5 minutes.
    • Open battery compartment from the rear.
    • Disconnect old battery (remove negative/black first, then red).
    • Remove battery (take note if it’s stuck—swollen batteries can be tough, don’t force them).
    • Connect new battery (red/positive first, then black/negative), then close the door.
    • Plug in and let the UPS recharge for 8 hours before testing on load.

What NOT to do

  • Don’t attempt a swap with the UPS powered or plugged in—risk of shock and damage.
  • Don’t try to mix an old and new battery—replace as a matched set (BC850RNC only uses one, but applies for other models).
  • Don’t force out a swollen battery. If stuck, contact us for guidance.
  • Don’t ignore new alarms or odd behaviour after install—if you see persistent errors, get service advice.

If the UPS serves a really critical load (like a server, medical device, or switch), or you encounter high voltage wiring, odd alarms, or burnt smells, stop the job and contact GDFTech.com for field service. Safety first.

Common Wrong Orders (and How to Avoid Them)

  • Ordering an APC "RBC" cartridge—Tripp Lite batteries are generic AGM VRLA blocks, not proprietary packs
  • Assuming it’s a multi-battery series—BC850RNC uses only one 12V block, not two
  • Choosing the wrong voltage—a 24V battery will not work and will damage the UPS
  • Speculating on battery size—physically measure your old unit if moving to a higher Ah
  • Buying bargain non-VRLA/fire alarm batteries—these lack safety certifications for UPS cycling

FAQ: Tripp Lite BC850RNC Battery Replacement

What type of battery does the BC850RNC use?

The BC850RNC uses a single 12V 7–9Ah sealed lead-acid (VRLA) battery. We recommend the BC900Lan (Replacement) Battery for fit and performance.

How do I know if my UPS battery needs to be replaced?

Watch for reduced runtime, constant beeping, flashing alarms, or any physical damage to the battery (swelling, leaks). See our UPS Battery FAQ for details.

Is it safe to replace the battery myself?

Yes, as long as you power down and follow the steps outlined above. Never attempt battery replacement while the UPS is live or connected to loads.

How long should I let the new battery charge before a load test?

Let it charge for at least 8 hours. Run a self-test afterwards to confirm the green LED shows steady operation.

Can I use a higher Ah battery?

If the battery fits the compartment and matches the 12V voltage, a higher Ah may provide slightly longer runtime but check compartments for size limits. Call us if you're unsure.

My UPS still alarms after installing the new battery. Now what?

There could be a deeper fault, or your battery bay connection might need reseating. Persistent errors, overheating, or burning smells mean it's time to book service with GDFTech.

How soon can I get a replacement shipped in Canada?

In-stock batteries from UPSPlusBattery ship in 1–2 business days from Montreal. You'll get tracking as soon as it leaves our warehouse.
