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.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
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.
You're using something like a power bank or some no-name mystery cell with a really low current (inexpensive) protection circuit. The battery can supply more than enough current for your application and should never fall below 2V even if it is at 3.5V at a worst-case load of 4A.
It’s the opposition within the battery to the flow of current. As batteries age or undergo multiple charge-discharge cycles, their internal resistance increases. This increase can lead to a situation where, despite showing adequate voltage, the battery can’t deliver enough current, resulting in no effective amperage.
Avoid using lead-acid battery chargers, as they have different voltage levels. Frequent Charging: To extend the life of lithium-ion batteries, they should be charged before reaching a low state of charge, ideally when they’re at around 80% capacity. Avoid allowing them to fully discharge before recharging.
