Over time UPS batteries wear out; this leads to a loss of power capacity and runtime.

Over time UPS batteries wear out. This leads to a loss of power capacity and runtime. Here are four reasons why you should only use genuine APC RBCs in your APC UPS:

Use of a non-APC battery will void APC's Equipment Protection Policy

APC recycles used batteries and almost 100% of the battery lead content is reused, protecting the environment. With each purchase of a genuine APC replacement battery, you get free freight back to APC for proper disposal of your old batteries (currently available in USA only.)

APC provides a 1-year warranty on each Replacement Battery Cartridge.

APC supplies the appropriate instructions for your UPS, along with any needed wires and connectors. All connections are made with high current gas-tight crimps for high reliability.

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 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.
