Does the DeWalt 20V Battery Degrade Over Time?

[kevin obroy]

Yes, the Dewalt 20v battery can degrade over time, just like any lithium-ion battery. With regular use, the battery’s ability to hold a full charge slowly decreases. Factors like frequent charging, extreme temperatures, and deep discharges can accelerate this degradation. Typically, after 2-3 years of heavy use, you might notice shorter run times. Even when not in use, batteries can lose capacity if not stored properly. It’s important to keep them in a cool, dry place and avoid overcharging. While DeWalt batteries are built for durability, they’re not immune to wear. Watching for early signs like slower charging or faster draining helps you plan for a replacement before it affects your work.
