Grab your Phillips, it's...
The Latest from The Screwdriver List!
Re your UPS: I think you probably can replace the battery and have that
solve the problem you have noted with it not keeping a charge--probably.
The main caveat is that if the charging circuit is not working, then of
course, the new battery will fail to get charged.
I have no idea what a new battery for that unit would cost. There are two
ways to go, depending on where you are. One is to contact APC and ask them
their price. The other is to take out the existing battery, take it to a
battery specialty shop and see if they can replace it with an equivalent
unit. That latter approach might save you some bucks, but it could also
void any warranty that might remain on the unit, and it *might* not work as
well as a new, factory-specified battery.
The other thing you may wish to consider is whether or not this unit has
the ability to notify the attached PCs when it is about to shut down
(because its battery is about exhausted). If it doesn't have that ability,
you may do better to buy a new one that does have it, so you can get your
PCs to shut themselves down gracefully before the UPS power dies.
