[NBLUG/talk] OT: Anyone ever replaced a battery in a UPS?

[Dave Sisley]

I don't want to hijack this thread, but want to pose a question of my 
own.  I have quite a few UPS's piled up - and I have no way of knowing 
if they are any good (although some have 'failed' and now I know maybe I 
can replace the battery).

What's the best way to test a UPS?  I don't have any sort of voltmeter 
or whatever (but if that's what I need, I'm off to Radio Shack).   
Obviously, battery-time is dependant on how many things you have plugged 
into it, but is there a way to quantify how much juice a charged UPS can 
deliver?

TIA,

-dave.
