The slow charging method is by far the easiest and safest way to solve lithium battery problems. You have to use the same battery to apply only a low current for the slow charge. The slow charge method is a docile approach in which you gradually restore the battery’s functionality.
It depends on the cause (of battery failure). If the battery is not physically damaged, or not moisture infected, and hasn’t aged excessively, The lithium-ion battery can be restored using several techniques like slow charging, parallel charging, using a battery repair device et cetera.
Preventing lithium battery problems is key. Guarantee proper charging practices, avoid exposing your device to extreme temperatures, and always use genuine batteries. Remember, safety is paramount when dealing with lithium-ion batteries.
A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
Common problems with lithium-ion batteries include rapid discharge, failure to charge, unexpected shutdowns, and battery drain in idle devices. These issues can relate to energy-demanding apps, damaged ports, or flawed batteries.
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.
