Yes, for some situations, we can repair our batteries by ourselves.
Totally, a lithium battery is made up by those components:
2.Prismatic Lithium battery cells
3.BMS (Battery Management System)
4.Connectors (wires, bus…)
We can separately replace above components because they can be bought in specialized battery stores.
Before you repair your lithium battery, be extremely cautions and follow following rules:
If you detect one of the higher-risk signs previously mentioned, your lithium battery cannot be repaired and should be handled with maximum care. We advise you to bring it to a battery store. They will take your battery to a recycling center.
If you only detect the lower-risk signs, you will be able to fix your lithium battery either at home or with the help of a battery specialist.
Let battery specialist evaluate your BMS and cells
Let battery specialist measure the voltage and capacity of each cell.
Let battery specialist test BMS.
If these are under-performing, they will be replaced.
