Lithium Ion batteries – storing with low charge means a dead battery

Filed under: Uncategorized — kenjun @ 10:02 am

If a Li-ion battery is stored with too low a charge, there is a risk of allowing the charge to drop below the battery’s low-voltage threshold, resulting in an unrecoverable dead battery. Once the charge has dropped to this level, recharging it can be dangerous. Some batteries therefore feature an internal safety circuit which will prevent charging in this state, and the battery will be for all practical purposes dead.
