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 have no experience with UPSes, but I have used LFP batteries a fair bit.

    The main compatibility issue will be the battery voltage and charging system. Most Li-based batteries have slightly higher nominal and charging voltages than lead acid types depending on the cell configuration.

    Check the specs on your UPS model to be sure it is compatible and if it is, I’d go with LiFePO4 (LFP) batteries rather than other Lithium chemistries at this time. They don’t weigh as much as the equivalent lead-acid batteries, are roughly the same size for the same capacity and handle deep discharge better than lead-acids. Plus LFP batteries aren’t as volatile as some other Lithium batteries.
