APC RBC6 Replacement Battery Cartridge #6 APC RBC6 Replacement Battery Cartridge #6

Pros: My previous battery lasted 5 years. Securely packaged with thick foam. Hot swappable.

Cons: Not a con, but mine didn't ship charged like another reviewers, so don't bet on it.

Other Thoughts: Official APC replacements are twice as much as some no-name brands you may find, but when you have thousands of dollars worth of equipment on the line and a 5 year life span for official batteries, it's a clear choice.

Pros: It works as it should.

Cons: With the cost of the battery it almost makes sense to just trade in to upgrade your unit.

Other Thoughts: The original battery in my SmartUPS lasted 7+ years so hopefully this one is just as good. Always been happy with APC UPS units.

Pros: It works. It came fully charged (APC's literature made it seem like it would have to be charged for 6-8 hours before running self-test.)

Cons: Purchased through Newegg, so I'll have to find some other option for properly disposing of the old battery.

Other Thoughts: I bought a Smart-UPS (SUA1000) second-hand for very little cash, its battery charged fine but wouldn't pass the self-test. I wasn't sure the battery was the problem, because it charged and had the right voltage at the terminals, but with this new battery it's working properly.

Normally I would have used APC's trade-in program, but it wouldn't give me any credit for this particular UPS. Newegg had the battery slightly cheaper.
