DEWALT 20V MAX 4.0Ah Lithium Ion Battery with 12V to 20V MAX Charger on sale for $51 at Home Depot

Final Price Breakdown

Original price: $179 Sale price: $51 You save: $128 (72% off)

Getting a 4Ah battery and a charger together for $51 is a steal. A single 4Ah DEWALT battery often runs more than this on its own, so the charger is basically along for the ride.

Why This Tool Is Worth It

Batteries are the lifeblood of any cordless shop. You can own the best tools on the market, but if you are always waiting on a charge, you are losing time. Adding a 4Ah pack to your lineup means longer runtime between charges and one more battery ready to swap in when the first one taps out.

What makes this one smart is the balance. The 4Ah capacity gives you extended runtime, but it carries the same size and weight as the compact 3Ah pack. So you get more power without the extra bulk. The onboard fuel gauge with a 3 LED charge indicator lets you check your charge at a glance instead of guessing.

If you already own 20V MAX tools, this is one of the easiest upgrades you can make for your shop.

Who This Is Best For

This deal is perfect for any woodworker, DIY homeowner, contractor, or weekend warrior already in the DEWALT 20V MAX family. If you have ever stopped a project to wait on a dead battery, this fixes that fast.

It belongs in a home shop, a garage, or a job site truck box. Furniture builders and remodelers who run drills, drivers, saws, and sanders all day will appreciate the longer runtime. And since it works across the full 20V MAX system, you can move it between every tool you own.
