LiFePO4 Battery Revival with multimeter
Tools
These are some common tools used to work on this device. You might not need every tool for every procedure.
The lithium iron phosphate (LiFePO4) battery is a variety of lithium-ion battery. Compared to conventional Li-ion batteries, it has a somewhat lower energy density and voltage, but has good durability and is significantly safer.
Some newer UPSes and electric cars contain LiFePO4 batteries.
Nominal voltage per cell: 3.2 V
Maximum charging voltage: 3.6 V
Discharge cutoff voltage: often 2.5 V
