Our take on the DeWalt 20V MAX Lithium Ion Battery 4-Pack

This is a four-pack of DeWalt 20V MAX lithium-ion batteries: two 4.0 Ah XR packs for heavy-duty tools and two 2.0 Ah compact packs for lighter work. All four fit any DeWalt 20V MAX tool and charger, and each has a built-in LED fuel gauge. The pack weighs about 4.4 lbs and charges in roughly 45 minutes per battery on a DeWalt 20V MAX charger. The lowest price on record is $159 at Arbor as of October 29, 2026, and that is also the only price seen so far, so there is no cheaper point to wait for yet.

Questions and answers

Is the four-pack worth it over buying single batteries?
At $159 at Arbor as of October 29, 2026, you pay about $40 per battery, which is well below typical single-pack prices for 4.0 Ah XR packs. It makes sense if you already own DeWalt 20V MAX tools and chargers.
Will these fit my older DeWalt 20V tools?
Yes. All four are DeWalt 20V MAX packs and work in any 20V MAX tool and charger, including older drills, saws and impact drivers.
What is the difference between the 4.0 Ah and 2.0 Ah packs?
The 4.0 Ah XR packs hold twice the charge and suit saws, grinders and other high-draw tools. The 2.0 Ah compact packs are lighter and better for drills, drivers and quick jobs.
How long does a battery take to charge?
About 45 minutes per pack on a DeWalt 20V MAX charger. A full four-pack takes roughly three hours if you charge them one at a time.
What is in the box?
Two 4.0 Ah 20V MAX batteries and two 2.0 Ah 20V MAX batteries. No charger and no case are included.
When is this pack cheapest?
The lowest price seen so far is $159 at Arbor as of October 29, 2026, and it has not moved since. DeWalt battery bundles often drop during spring and holiday sales, so watch for a lower price then.
