Product Reviews
APC Replacement Battery Cartridge #21 RBC-21 is rated 3.4 out of 5 by 5.
Rated 5 out of 5 by from money saver this is cheaper than purchasing a new unit. batteries are easy to install.

Rated 1 out of 5 by from Short life for service rendered The replacement battery only lasted s couple of years and is awfully expensive for what was not more than a total of about 180 seconds of providing backup power during that period. Battery technology can be MUCH better than that.

Rated 5 out of 5 by from Works This battery works as advertised. The one it replaced never quite did. The method of getting it and returning the old battery for recycling was straightforward.

Rated 5 out of 5 by from Works great Battery came with easy installation instructions. Battery change was easy. Swapped batteries and had it reconnected within 10 minutes.

Rated 1 out of 5 by from Battery Bad in the Box? Installed replacement battery in my APC Back-UPS 500 VA, but immediately a warning tone was heard along with "replace battery" light. Tone and light don't go out until you physically detach battery from leads inside the unit. Have requested guidance from customer service; will advise further once I hear anything from them.
