Charging speed matters, especially when you’re in the middle of a project. Dewalt offers chargers that can recharge these batteries relatively quickly. From my experience, a 4.0 Ah battery can take about an hour to charge fully. Also, lithium-ion batteries tend to hold their charge well when not in use and have a long overall life span if properly maintained.
Durability and Build Quality
I appreciate the rugged build of Dewalt batteries. They have protective features to withstand drops, impacts, and harsh job site conditions. This durability gives me confidence that the battery will last through tough use.
