Rated 5 out of 5 by Deuce from Very SatisfiedThe battery catridge died in my home theater UPS (APC S15) after five years of intermittant use. What finally killed it was running the TV for over four hours when tornados took out our main power and passed around us. When power came back up a week later, it failed the APC unit's self check. APC's customer service bumped me up to higher level customer rep and he ran through the checks for me. He quoted me a price for a new one when it failed again. I placed the order and then received it within three days. The local battery store happily took the old one for recycle.
