Frequently Asked Questions

How long does a DeWalt battery take to charge?

Charge time depends on battery capacity and charger type. A standard DeWalt 20V charger takes 60–90 minutes for a 5.0Ah battery. DeWalt FLEXVOLT chargers can charge 6.0Ah in about 35 minutes.

Can a DeWalt battery be repaired if it won't charge?

Individual cell replacement is possible for skilled DIYers, but DeWalt batteries contain cells under high voltage — improper handling is dangerous. Most users replace the battery pack.

How many times can a DeWalt battery be charged?

DeWalt lithium batteries are rated for approximately 300–1,000 charge cycles depending on the battery series. Capacity gradually decreases after each cycle.
