Picture this:

In front of you is a large gift; the perfect size. You think you know what’s inside, and it’s exactly what you asked for. After the requisite small talk (“I wonder what it is!”), you’re given the go ahead. You can barely contain yourself. Soon, the perfect gift is sitting in front of you, the wrapping paper lies shredded on the floor.

Squealing, you open the box, and go to plug in your brand-new toy. Then it hits you. The starburst on the side of the box: “batteries not included.”

This is all to say: batteries are important. Whether you’re charging a new toy, or your DeWalt 20V Max Impact Driver, they’re essential for a good time, though they often go forgotten.

So allow Amazon to bring batteries back to the fore with this great deal on a 2-Pack of DeWalt 20V Max Batteries, available for 42% off this week from your favorite e-tailer.

At over $100 off, this 2-Pack of batteries – already a must-have at list price – have entered the rarified echelon of the double-must-have. Nab them while you still can; double-must-haves tend not to stick around for very long!

The DeWalt 20V MAX Battery 2-Pack is strong enough to provide three times the capacity of the compact XR battery pack, and two times the capacity of DeWalt’s standard battery pack. Easy-to-charge, easy-to-use, and easy on the wallet, this two-pack of batteries from DeWalt is a no-brainer for lovers of great deals.
