APC Back-UPS Replacement Batteries

What is an APC Back-UPS replacement battery?

The Back-UPS family, entry Back-UPS BE / BX / BVN and line-interactive Back-UPS Pro BR / BX, uses sealed lead-acid (SLA) cartridges in a defined APCRBC (APC Replacement Battery Cartridge) configuration. The cartridge is replaceable when the cells reach end of service life (APC gives 3 to 5 years on most models, 2 to 5 on some). UPSPLUSBATTERY.CA stocks compatible replacement cartridges for the Back-UPS line.

For Smart-UPS line-interactive cartridges (APCRBC123, 132, 133, 143, 124, RBC43, RBC55, etc.), see APC Smart-UPS replacement batteries. For Smart-UPS SRT and Smart-UPS Ultra (APCRBC140, 141, 152, 155, SRTL180RM2UBP), see APC Smart-UPS RT replacement batteries. For the full APC battery catalog see APC RBC batteries.

Back-UPS to APCRBC cross-reference

Cartridge spec is on the unit label (typically the side or back of the chassis) and listed in the user manual. If the label is worn off, send the model number to our team and we'll cross-reference.

How to identify the right cartridge

Method 1: unit label

Every Back-UPS has a label listing the model number and compatible APCRBC. This is the definitive reference: if the label says APCRBC124, that's the part you need.

Method 2: existing cartridge

Open the battery door and read the label on the existing cartridge. Lists cell count, voltage, and Ah: match to the same configuration in stock.

Method 3: model number lookup

Use the cross-reference table above. APC lists the replacement battery on each model's data sheet at se.com.

APC vs compatible aftermarket

Two categories sit under the APCRBC umbrella for Back-UPS. Both power the UPS correctly.

APC OEM: cartridge supplied by APC, with the manufacturer's warranty. An in-warranty unit or a service contract may require it; check the terms.

Compatible aftermarket: Same form factor, connector and voltage as the original cartridge. 1-year UPSPLUSBATTERY warranty. Suitable for out-of-warranty units kept in service.

How long do Back-UPS batteries last?

APC gives 3 to 5 years of battery life for most Back-UPS models (2 to 5 on some), in a climate-controlled room. Three factors shorten life:

• Ambient temperature. Every 8 °C above 25 °C roughly halves life.
• Discharge cycles. Frequent outages or unattended self-tests consume service life.
• Float voltage and charging algorithm. APC's temperature-compensated charging extends cell life on cartridges.

The front-panel indicator on most Back-UPS, and PowerChute Personal Edition, show a replace-battery alert. Replace promptly: the UPS continues to power the load but rated runtime is no longer guaranteed. Read when to replace UPS battery.

Installation

Most Back-UPS use bottom-access or rear-access cartridges. Procedure:

1. Order the correct APCRBC for the model.
2. Slide the cartridge door open (some BX / BR models have a screw-fastened cover).
3. Disconnect the polarised battery plug.
4. Slide old cartridge out, slide new one in.
5. Reconnect the polarised plug until it clicks.
6. Close the door and (where supported) reset the install date via the front panel or PowerChute.

Recycle the old cartridge at a municipal hazardous-waste depot or Call2Recycle drop-off, or return it to us with your new cartridge order for recycling. Read how to install UPS battery.

Warranty and support

APC cartridges carry APC's own warranty (APC's data sheets give 12 months on the battery of current Back-UPS models). Compatible aftermarket cartridges carry our 1-year UPSPLUSBATTERY full-replacement warranty. Coordinated through our Canadian team. Shipped from Canada: see shipping policy for rates and timing.

FAQ

What does APCRBC stand for?

APC Replacement Battery Cartridge. APC's part-numbering system for replacement cartridges across Back-UPS, Smart-UPS and SRT.

How do I find which APCRBC I need?

Check the unit label on the side or back of the Back-UPS. The compatible APCRBC is listed there. Alternatively, use the cross-reference table above or contact our team with the model number.

Aftermarket vs APC: does it matter?

For an in-warranty unit: check the APC warranty terms first. For an out-of-warranty unit: a compatible cartridge matched on voltage, capacity and connectors is the usual choice.

How often should I replace?

Every 3 to 5 years in a climate-controlled room (APC's figure), earlier in hot ambient. Replace immediately when the front-panel LED or PowerChute flags battery as "replace."

Can I install it myself?

Yes: Back-UPS cartridges are user-replaceable. No tools needed on most models. How to install UPS battery.

Battery warranty?

APC: APC's own warranty (12 months on the battery of current Back-UPS models, per APC's data sheets). Compatible aftermarket: 1-year full-replacement UPSPLUSBATTERY warranty.

Disposal?

Sealed lead-acid cartridges are fully recyclable and should not go in household trash. Drop at any municipal hazardous-waste depot, Call2Recycle collection point, or ship back to us for recycling.
