ai6yr, #DisasterPrep and #IT task of the day: replaced the batteries in one of my #UPS units. Noticed a couple of days ago the fan was running constantly... because the UPS was attempting to boil off the rest of a (dead) 12V battery. Bought the $$$$ expensive local Batteries Plus batteries on recommendation of an IT data center manager I know. (have had very bad luck w/online battery purchases).
