Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
Effects of Leaving a Battery on the Charger Leaving a lithium-ion battery on the charger for an extended period has its consequences. One major effect is that it can lead to decreased battery life over time. When a battery remains connected to the charger even after it’s fully charged, it continues to receive small amounts of electrical current.
In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
In the case of lithium-batteries, this can lead to the cell opening and possibly burning down. “With lithium-polymer batteries, it should also be noted that gas formation can occur in the cell, which leads to the severe swelling of the cell.” The next step would also be thermal runaway and, thus, burnout.” And what about deep discharge?
This means that the temperature in the cell continues to rise and chemical reactions start from it, which proceed exponentially. These reactions can no longer be stopped,” explains Dr. Jürgen Heydecke. In the case of lithium-batteries, this can lead to the cell opening and possibly burning down.
This means the battery will only charge if left on the charger, addressing concerns about leaving devices plugged in overnight. Storing lithium-ion batteries at full charge for an extended period can increase stress and decrease capacity. It’s recommended to store lithium-ion batteries at a 40-50% charge level.
Will my Li-ion battery be damaged if I leave it plugged in
If the BMS cuts off the charge, you''ll be fine. However if somehow keeping it plugged in keeps charging it to 100% over and over, it will degrade the battery. Lithium-Ion batteries more or less drop voltage down to 95% naturally, and recharging …
