EV>The past few days my system powers off unexpectantly.

EV>It looks like my UPS need a new battery in it.

EV>The UPS was bought in August of 2010 and 5 Years battery life sounds right
EV>to me to get a replacement from what I read about UPS Batteries.

teh main factor in replacewment is total run time on hte batteries if
you rarely have power outages you xcan expect more then 5 years.
Somewhare i nmy rats nest I have a computerized battery tester I used to
use for my Ham Station exergency batteries. Id did a test discharge
curve plot and when the batteries were less then 50% of their AH rating
I reppaced them.
