What is the self discharge rate a lithium ion battery?
Lithium ion batteries have a very low self-discharge rate and can be stored for several months with minimal capacity loss. 24. Does it hurt DEWALT batteries to leave them in the charger? No. All DEWALT chargers have an automatic tune-up mode which allows batteries to remain in the charger, maintaining a fully charged pack until the user is ready to work. If NiCd batteries are stored outside of the charger, they will discharge naturally, 15-20% the first 24 hours, 7-10% the next day, and about 1% every day there after. NiCd batteries lose the bulk of the capacity when outside of the charger in the first 3 days. In fact, it is better for the battery to leave it in the charger to be sure it goes through Equalization and Maintenance Modes. Nano-Phosphate Lithium Ion batteries have minimal self discharge. However, it is still recommended to leave the battery in the charger to be sure it goes through Equalization and Maintenance Modes. 25. Can DEWALT chargers be run off of a generator? Yes.
