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.
People using lithium battery packs have to be careful of over-discharge as much as overcharging of the battery. Lithium-ion battery chemistries should never have the voltage fall below 2 volts. This issue can happen when the battery is placed into storage for long periods of time or when discharged too much.
The voltage output of the charger must meet the voltage requirements of the lithium battery pack to ensure safe and efficient charging. Using a charger with incorrect voltage output will result in overcharging or undercharging, which may damage the battery and shorten its life.
However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature. For instance, a typical lithium-ion cell might show a voltage of 3.7V at 50% charge.
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. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected.
