If there are undervoltage cells, open the battery caps and fill each compartment with water to optimum levels or electrically add a desulfation device. When it comes to recovering a lithium-ion battery pack from 0V, the first thing to check is if the BMS BMS has tripped or failed.
Recovering a Lithium-Ion battery cell from zero volts is not recommended, as it can result in a fire. This is because once the cell goes under about 2.5 or 2.6 volts, a chemical reaction occurs inside the cell that permanently damages it and drastically increases its internal resistance.
Lead acid cells and battery packs can be recovered from 0V and used with almost the same performance as before. However, lithium-ion cells are too sensitive to over-discharge to be recovered from 0V and used in most applications, and cannot be serviced. To recover a lead acid battery, charge it for 10-12 hours and then measure the terminal voltage.
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
On another note, if you measure 0V from a li-ion, it might just be that its protection circuit has disconnected it from the terminals to prevent a deep discharge. Depending on how that protection circuit is designed, you can recover the battery by simply charging it. Or the protection circuit might act like a fuse and never reconnect the terminals.
