Two DEWALT 20V MAX compact 4Ah batteries that deliver extended runtime in a lightweight design, compatible with all 20V MAX tools and chargers.
Categories : tools
SKU : WOR-TOO-336
The DEWALT 20V MAX 4Ah Battery 2-Pack (DCB240-2) gives you two high-capacity compact batteries that keep your tools running longer. With a 4Ah capacity, the DCB240 delivers up to one-third more runtime than the 3Ah DCB230, while maintaining the same small footprint and weight. That means more work between charges, with less fatigue during overhead use.
Each battery features a 3-LED fuel gauge to show remaining charge, so you can plan your work without surprises. The compact design is compatible with the entire DEWALT 20V MAX system, so it works with your existing tools and chargers.
If you're using a DCB115 charger, a fully depleted 4Ah battery reaches a full charge in approximately 1 hour. That's a 60-minute turnaround for each battery, so with two batteries, you can rotate them and stay productive. For faster charging, the DCB118 charger reduces the time to about 45 minutes. Charge times can vary slightly based on battery temperature and age.
These batteries are compatible with all DEWALT 20V MAX tools, including drills, saws, and impact wrenches. They also charge on any DEWALT 20V MAX charger. The 4Ah capacity is ideal for high-drain tools like circular saws, while the lightweight design keeps the tool balanced.
To extend battery life, store them in a cool, dry place, avoid dropping, and keep contacts clean. Charge at room temperature and avoid storing in extreme heat.

Lasts long.
These batteries are light and last. I get a full day of use. Great buy.
I bought these to replace my old batteries. They are indeed lighter than the originals and seem to hold a charge longer. I've used them in my drill and saw. The fuel gauge is convenient. They charge quickly with my standard charger. I wish they came in a case, but they are fine. Overall, very satisfied.
I'm 25 and a DIYer and these are perfect. They're light and last long. I can use my tools for hours without recharging. The price is right.
I'm 38 and use my tools professionally and these batteries are reliable. They hold up well under heavy use. The 4Ah capacity is ideal. They fit all my 20V tools. Highly recommend.
I'm 66 and not a heavy user, but these batteries are great. They charge quickly and last me several days. The fuel gauge is easy to read. I'm glad I bought them.
They work well, but I think they're a bit expensive. Still, they last a long time. I'd wait for a sale.
I've been using these for a month. They're great. The battery life is impressive. I've used them in my impact driver and drill. They don't add much weight. Very happy.
