What this part is

The RBC24 is a replacement battery cartridge made and branded by APC, which is the distinction that matters most on a part like this. A UPS battery is not a commodity cell in a box. APC assembles the cells into a tray or enclosure with the connectors, fusing and spacing the host unit expects, and the unit's own charger and runtime calibration are built around that assembly. Third-party cartridges built to the same outline exist and are cheaper. They also put an unverified assembly inside the one device whose entire job is being the thing that does not fail, which is a poor place to save money.

Electrical rating

APC's data sheet for this part number publishes neither a nominal voltage nor an amp-hour figure. That is a verified absence rather than something we failed to look up, and we would rather say so than fill the gap with a sibling cartridge's numbers. Chemistry is sealed lead-acid, sealed and valve-regulated. In practice the electrical rating is not the number you order against anyway. The cartridge either seats and connects in your UPS or it does not, and that is decided by the part number, not by matching volts and amp-hours to something similar.

Fitment before ordering

Order against your UPS model number, not against this cartridge's dimensions. APC publishes no compatibility list on this part's own data sheet. There is an APC cross-reference document covering the whole range, but it is not reproduced here: a fitment list that is wrong in one row costs you a return and a UPS that is still down, which is worse than not publishing one at all. So the process is simple. Send us the model number printed on the front or the rear label of your UPS, and we will confirm whether this is the correct cartridge for it before anything ships. If it is not, we will tell you which one is.

Handling and installation

Physically the cartridge is 3.3 in (83 mm) H x 8.5 in (216 mm) W x 13.5 in (343 mm) D. It weighs 26.4 lb (11.96 kg). It is manageable single-handed, though it is denser than its size suggests. APC does not publish a hot-swap statement for this part number on its data sheet, so we do not make one. Some Smart-UPS models genuinely support a live cartridge change and some require a shutdown; check the manual for your specific UPS before planning the work, or ask us and we will check it with you.

Included and warranty

APC lists the following supplied with this part number: All required connectors, Battery recycling guide, Metallic battery tray or enclosure, Reusable packaging and Installation guide. Warranty is 24 months. Keep the packaging until the swap is done. APC ships these in reusable cartons specifically so the old cartridge has something safe to travel back in, and a recycler will generally want it boxed rather than loose. If you would rather we confirmed the part against your UPS before it ships, say so when you order and we will do exactly that.

If you are renewing the batteries in an APC Smart-UPS and this is the cartridge your unit calls for, the RBC24 is the genuine part and we hold it in stock. Send us your UPS model number and we will confirm the fit before anything ships. Contact us to learn more or secure this solution for your business today.
