My UPS (APC) has faulty batteries (again). 3 years old, already fried. I don’t mind the poor capacity of the PbAc batteries but this life cycle is horrible (2-3y tops).
Can I replace them with equivalent LiFe batteries like the ones you find on Amazon and such with the same form factor?
Or are there LiFePo4 UPS available in Europe?


Keep in mind that this isn’t my personal experience talking here. I also don’t know if the user in question is correct, or if it might be specific to some portion of the respective brands — both make a wide range of UPSes, from inexpensive to pretty pricey. But I did remember reading that, and it did seem potentially germane to OPs problem, so…shrug
Someone with a multitester or oscilloscope or something and some of those units could probably examine further, see what the actual behavior is for a given model.
