3. DOES IT HURT DEWALT BATTERIES TO LEAVE THEM IN THE CHARGER?
No. The DEWALT chargers have a maintenance mode which allows batteries to remain in the charger, maintaining a fully charged pack until the user is ready to work. If DEWALT 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. One of the benefits of DEWALT XRP™ Lithium Ion batteries is that they have limited self discharge. Storing DEWALT Lithium Ion batteries outside of the charger will not result in loss of charge.
