From my read of the APC forums, UPS batteries (in APC UPS's) seem to have a "Life" of about 3-5 years. 3 years seems to be about average. Odd to me that I got damn near 9 years out of my first set of APC batteries. [I do so want a set of 1997 batteries!] But, there was a whole lot of stuff that took place during that time period. I got really lucky!
It depends on usage. If you never have a power failure the batteries will last a lot longer than if you use them a lot.
What you should try to do is to make sure they never never NEVER go under about a 60% charge.
Get a battery under 60% and they never really recover. Christopher Fisk -- BOFH Excuse #262: Our POP server was kidnapped by a weasel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
