Replacing The Batteries In Your APC RBC143 Cartridge

15 September 2023  |  Tom

Replacing the batteries in an APC RBC battery kit is the most environmentally friendly and economic solution

Here's how to replace the batteries in an APC RBC143 replacement battery cartridge

The APC RBC143 cartridge requires a kit of 10 batteries - you can order them here - we supply high quality CSB batteries, the same as originally fitted by APC themselves.

Replacing the batteries is a fairly straightforward job for anyone with reasonable DIY skills. You'll need to reuse any existing cables and connectors and take great care to replace the new batteries exactly as the old ones came out.

Ideally replace the batteries one at a time, like for like, or if this is not practical take photos of the existing layout before you start.

Here's a step by step guide to how to replace the batteries in your APC RBC143
