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?
Yep, specially with lower quality UPS the lead batteries degrade in a year or two to an useless state. I doubt you can simply replace them and I wonder about LFP UPSs as well.
