I have a very odd issue at the moment with a 5P1000 that is just about crossing into about 3.5 years of service. A couple weeks ago I noticed that the battery fault alarm would trip and clear about every other self-test interval so naturally I figured the battery module might be failing and replaced it earlier this week. Upon doing so, the unit ran fine for a couple days and all of a sudden this evening I received an email alert from our instance of Eaton Intelligent Power manager that a battery fault had yet again been detected on the unit. Is this a sign of charger/UPS circuitry failure manifesting itself as a battery failure? The battery module I received is practically fresh off the assembly line (couple of weeks old at most) and showed a good open circuit voltage prior to me installing it. I did check with Eaton single phase...
