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. Due to contact resistance or detection of charge, the current is inconsistent caused by the uneven charge of the cell.
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?
If you’re grappling with a lithium-ion battery that refuses to charge, here are some detailed steps to potentially fix the issue: Cleaning and Maintenance To start, let’s address potential hindrances like debris, dust, or corrosion:
Yes. A lithium-ion battery pack that has one or more bad cells can be extremely dangerous, especially if it's put under a heavy load. Battery packs are made from many lithium-ion cells. So if one goes bad, it's more than likely going to negatively impact the surrounding cells.
Always use a charger that conforms to the specifications of your battery pack. This means if you have a 36-volt lithium-ion battery that needs a 42V charge voltage, don’t attempt to charge that battery with a higher voltage battery hoping that the BMS cuts off the charge.
Battery packs are made from many lithium-ion cells. So if one goes bad, it's more than likely going to negatively impact the surrounding cells. If left unchecked, a bad lithium-ion battery can overheat and go into thermal runaway, which is never a good thing.
