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?


I’ve heard that yes this is safe, though I’ve only done this with automotive stuff personally
