DEWALT's power tools tend to last quite a while, but their original batteries may not. Rather than replacing a perfectly good tool, a replacement battery can make your tool feel brand new or better. All of their batteries are not compatible with all devices, however, so make sure you check the voltage before purchasing. Some DEWALT batteries are compatible with more than one voltage, potentially allowing you to use them for multiple tools. DEWALT batteries are known for their long charges and lifespans, helping you get extra mileage out of your trusted tools. Some batteries come in packs of 2, and newer models may have LED power indicators.
