DeWalt 8.0Ah Battery for 20V Max Tools

DeWalt 8.0Ah Battery to Highlight Advanced Battery Line for 20V Max Tools

You may have heard the whispers of a DeWalt 8.0Ah battery for their 20V Max tools and the day is almost here! The batteries should be available from retailers on September 30, 2019, and they’re starting to show up for preorder.

The batteries will retail around $179 for a single and $269 for a 2-pack.


Here’s the description we found on ToolNut’s website:

“Our 20V MAX 8.0Ah Battery provides reliable power and long battery life. Using the latest lithium ion technology, it offers 8Ah capacity with minimal weight, offering ergonomic benefits for extended power tool use. A 3-LED Fuel Gauge system allows instant battery status checks. This battery is compatible with all DEWALT 20V MAX power tools and includes 3-Year Limited Warranty.”

At just 2.1″ tall, every indication is that the DeWalt 8.0Ah battery is a 2P pack, meaning it has 2 rows with 5 cells in each (10 cells total). That almost certainly means the battery is using 21700 cells.

To get the most out of this kind of battery pack, you have to upgrade the pack construction and improve the electronic communications going on. Once you do, product teams can design tools that deliver much greater power or extend runtime with more efficient battery use.

In moving to an advanced battery system, DeWalt joins several other major manufacturers. You can read more about their design details by clicking the links below.


What’s interesting is that DeWalt doesn’t seem to be attaching a flashy name to their advanced batteries just yet. It’s certainly not a requirement, but it is helpful to easily tell from the name which batteries are advanced and which are standard.

We’ll have to wait and see if there’s also a 4.0Ah slim pack on the way. DeWalt already has a 1P 3.0Ah battery to complement its 2P 6.0Ah pack, so there’s certainly a reasonable expectation that it’s coming.

What are you hoping to power with a DeWalt 8.0Ah battery? Any ideas as to what new tools DeWalt is working on to go with it? Let us know in the comments below!

6Ah 60v + 20v circular saw = better?
8Ah + 20v circular saw = better?
For the price of the new 8Ah batteries, I’d say the 6 or 9Ah 60v batteries are a better, future proof, investment.
What do you think?

Why not just buy a 9ah flexvolt battery?


I’m a 19 yr hardwood flooring contractor serving n. il and southern wi. I use the original 20v circular saw regularly as it has a shorter offset on the motor than the updated models and I can get closer to my work . I also skinnied up the saw deck for 1.5″ to 1.15″ for that reason when running the 4ah or 5ah batteries I sometimes have trouble completing daily tasks because of power and heat issues . hoping a larger capacity batteries will improve my usage


I don’t think Dewalt needs a fancy name for the new battery. Other manufacturers distinguish the different batteries because they are all 18v, but some are more suited for their higher power tools. In this case, it’s just a runtime play for Dewalt. All their high powered tools are 60v Flexvolt. So the differentiation is already there for the high power battery/tool. Everyone else is trying to figure out how to market high demand/power tools/batteries on the same voltage platform.
