The DEWALT® 20V MAX* Premium XR Lithium Ion 2-Pack gives you the power to run all of your 20V MAX-compatible tools. XR design delivers up to 33 percent longer running time than regular 20V MAX batteries. These batteries include a Fuel Gauge System that utilizes three LEDs to give you an indication of their remaining charge level. These premium battery packs don't develop a memory over time, so you're safe to put them on the charger even without running them down completely. They have a very low self-discharge rate so you can rest assured of having power even if they are off the charger for an extended period. Each DEWALT battery weighs just 1.42 pounds, which adds only a small weight to the tool you're using for greater comfort and strain-free operation.
