Ok i have a cyberpower cps1500avr that i have had for about 5 years and it runs fine on main power but only runs for mabay 5 mim whit a 65% load before it cuts out on over load i think(the led lights for load goes up to max and it beeps) I read the V on my batteries and under load they are 12.3, 12.2, 12 and 11.9. i have 24.2v one both sets under load(it has 2 sets of 24v in parallel). My clamp on meeter is showing about 10amp draw form both banks of batteries, temp of the ups is showing about 100 when its on battery power. and if i load it up to 85%+ the sec it goes to battery power my tv cuts out then comes back on then the ups goes down when it tries to come back on.
what could be causing this? does it sound like bad batteries or maybe i should open the case up and see if its just full of dust( when i pull the battery compartment out there was a lot of that heavy type of dust. any suggestions on what to do?
