Howdy gang..
I have a Fenton PowerPal 660 UPS.
This morning found The Cheese off air (shock, horror). Turns out there was a power cut this morning and my UPS failed.
Testing it, it seems that the UPS shuts off when power is removed, with or without any load.
I pulled the sealed lead acid battery out and tested it with a multimeter.. 13.2volts.
I can get a new battery for $52 which is my preference as it's cheaper than replacing (and kinder to the enviroment by throwing the unit out). But I don't want to go and waste money buying a new battery only to discover its the UPS itself.
So the question is, can a lead acid battery voltage dip like that even without load? Or should I suspect the UPS itself has developed a fault.
Any advice appreciated :)
