Your UPS is throwing a battery-replacement alert and the old cartridge is past its prime. You need the right APC cartridge, not a generic cell that might not seat properly or trigger a fault code.
The APC RBC23 is a genuine enclosed lead-acid battery cartridge, supplied with a metallic battery tray so it drops straight into your UPS bay. Everything's in the box: connectors, installation guide, recycling guide, and reusable packaging. One cable. One swap. No disassembly beyond removing the old tray.
Operating range 0–45 °C, storage down to −15 °C. Backed by a 2-year APC warranty.
If you're not sure whether RBC23 is the right cartridge for your unit, call us before you order — we'll confirm it against your UPS model number in under two minutes so you don't end up with the wrong part sitting on your bench
