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.
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.
Just cut off the connection and leave the battery aside for 30 mins. If it doesn't work, there are 2 more ways to jump start the battery: using an AC-DC lithium battery charger with 0V function or an MPPT solar charge controller to charge it for 3 to 10 seconds, then the battery can be used normally. 2. How do I know if my lithium battery is bad?
For lithium charge way slower than usual and see if the voltage comes back rather quickly. I usually do 10mA. If the voltage is really slowly climbing its likely already failed partial short and is gone. Which can be confirmed by disconnecting the power supply waiting a few minutes and measuring the voltage.
In some cases, a lithium-ion battery may show 0V on the output even though the cells are not really at 0V. This can happen when the BMS is either tripped or has failed. In these situations, reviving a lithium-ion battery from 0V is possible because the cells are not really at 0V.
