I am VERY surprised you've actually gotten that much life out of it! Based on 
my personal experiences with TrippLite, I'd heave it into the trash ASAP, and 
replace it with an APC. TrippLites have a very nasty design that repeatedly 
charges/discharges the battery, causing premature death. The worst part is that 
when the battery does finally succumb to this abuse, the unit starts cycling 
power on/off every two seconds until you smash it against the wall. I will 
*never* buy another one.

YMMV
