APC 24V Replacement Battery Cartridge #33 for UPS Systems

The APC RBC33 is a replacement battery cartridge built for select APC Smart-UPS and Back-UPS units. It restores the original runtime of your UPS so computers, networking gear, and other sensitive electronics can ride through outages and brownouts without shutting down.

This cartridge uses sealed lead-acid technology that never needs watering and resists spills. Because the battery is hot-swappable, you can install it while the UPS stays online, keeping connected equipment powered and protected. The cartridge ships fully assembled with the correct wiring harness and clear instructions, so most users can complete the swap in a few minutes and get back to work.

With an expected service life of three to five years, the APC RBC33 is a practical choice for home offices, small business server closets, retail checkout stations, and any environment that depends on an APC UPS for clean, uninterrupted power. APC also provides a convenient recycling program and ships the cartridge in recyclable packaging to support responsible disposal when the battery reaches end of life.
