Buy a new battery back up device.Tripp Lite,APC,or whichever brand name
you prefer.When the batteries (I think my APC Model 1000 has two
batteries) in my batttery back up get too worn out,I will go to a local
computer store and buy a new one with new fresh batteries in it.I won't
mess around.By the way,I get snail mail APC pamplets in my snail mail
box,whenever APC company sends them out.I guess a www.devilfinder.com
for,APC News Letters might turn something up.
