Rated 5 out of 5 by from Need 4 total batteries for APC5000 I didn't realize you needed two of these kits (which contain two batteries each) to fully populate an APC5000 UPS. De-energized all my server room hardware, pulled the old batteries out of the UPS, only to find out I didn't have enough new batteries on hand to replace them. Remember to buy two of these kits for the big APCs. Hopefully this helps someone avoid the embarassing realization I had that night!

Rated 5 out of 5 by from Pleasantly surprised..... The battery replacement was defected, but my IT person called and emailed ADP and was told that another replacement would be delivered and no charge. Well...to my surprised the replacement for the replacement arrived 1 day later. We were told that it would be 3-5 working days....All was good with the new replacement.

Rated 5 out of 5 by from Easy to install The batteries were very easy to install. If they give me another 8 years of life out of my SUA3000 I will be amazed. I was prepared to spend thousands on a new UPS when I found out I could spend hundreds and just replace the batteries. Thank you APC!

Rated 5 out of 5 by from Keeps Your Good Equipment Running Recently purchased these for a customer with an SMT2200 they've had for a while now. The cost for the replacement batteries may seem like a lot but when you consider the cost to replace the whole unit and the reduced waste from simply replacing the batteries, it's really a no-brainer.
