Our take on the DEWALT 20V MAX Battery XR POWERPACK 4Ah Lithium Ion

This is DEWALT's 20V MAX XR lithium-ion pack rated at 4.0Ah, the mid-size battery in the 20V MAX line. It fits every DEWALT 20V MAX tool and charger, so it works as a spare or an upgrade from the 1.5Ah and 2.0Ah packs that ship in kits. The only price on record is $63.90, seen on October 29, 2026, so there is no lower recent price to wait for.

Questions and answers

Is the 4Ah pack worth it over the 2Ah that came with my drill?: Yes, if you run tools for long stretches. The 4Ah roughly doubles runtime, though it adds some weight and bulk to compact tools.
Will it fit my older DEWALT 20V MAX tools?: Yes. It works with any DEWALT 20V MAX tool and charger, including tools sold with smaller packs.
Does it come with a charger?: No. This is the battery only. Chargers are sold separately or come in kits.
How does it compare with the 5Ah XR pack?: The 5Ah gives about 25% more runtime but is larger and heavier. The 4Ah is the better balance for drills and impact drivers.
When is the best time to buy?: The only recorded price is $63.90 on October 29, 2026. DEWALT batteries usually drop during holiday and spring tool sales, so watch for a bundle or multi-pack.
What do buyers say about the DEWALT 20V MAX Battery XR POWERPACK 4Ah Lithium Ion?: Rated 5 out of 5 from 6 ratings.
