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?
There are lifepo4 batteries that are drop in replacements for SLA car batteries. But there’s no guarantee that the more sophisticated circuitry in the UPS will accept it. (I’m not exactly sure what they’re using to make it a drop in replacement.) I would look to see if others have succeeded online. That kind of swap is something people would be posting all over YouTube if it works.
It was on YouTube like 6 years ago. I did it 4 years ago and they’ve been running great.
You need to get a lifepo4 that has a lead acid drop in BMS.
