The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.
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 long-term storage, it is advisable to charge lithium-ion batteries to about 50%. This intermediate charge level helps to preserve the battery's overall performance and prevent excessive self-discharge.
Lithium batteries degrade over time, losing their ability to hold a charge. If your battery is old or you’ve used it extensively, it may be reaching the end of its lifespan. Part 2. How do you fix a lithium-ion battery that won’t charge?
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.
Most lithium-ion batteries are designed to handle high drain rates without the need for full cycles. Partial discharges and subsequent recharges can help reduce the strain on the battery and prevent unnecessary wear. While some equipment may require a full discharge for calibration purposes, this is not typically necessary for lithium-ion batteries.
