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?

    Probably not. LiFePO4 keep their bulk at an even 13.7V

    Your lead-acid probably floats around 13.5-13.8V. the charger might pulse or occasionally go even higher to desulfate the batteries. That’d either leave your new expensive battery undercharged or worst case damaged (or have the BMS cut it off).

      Lifepo4 charges at 14.2. So it’s not only safe, but it means the lifepo4 is undercharged which dramatically increases its lifespan at the cost of runtime.
