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.
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.
If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. 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.
If the battery won’t activate and allow charge/discharge over 1A, severe overdischarge is likely. Self-discharge or parasitic loads can deplete cells below 10V. Use a lithium battery charger on activation or force charge mode to revive. The battery management system (BMS) cuts off discharge if the voltage drops too low, preventing cell damage.
The following are common issues and corresponding troubleshooting methods for lithium-ion batteries. Troubleshooting steps: First, it is necessary to confirm whether there has been over-discharge of the battery during use, and if the battery has not been activated by charging for a long period of time.
So in here in this post, we share with you some of the most commonly seen root causes to lithium-ion battery accident and their solutions. Hope our post help you with what you need.
