2013
2013. In 2013, DEWALT introduced its cordless 20VMAX* – XR line of Brushless power tools which includes brushless motors and high capacity lithium ion batteries.

In the most simplistic terms, Dewalt 20V Max = 18V. These aren’t 20V battery packs, they’re 18V battery packs. If you didn’t already know this, don’t worry, it’s not just you.

the USA 20V XR batteries ARE interchangeable with the UK 18V XR batteries, as they are apparently they are the same battery!

DeWalt has announced a new 20V MAX Battery Adapter that will work with most DeWalt 18V tools, which is set to release October 2015 (December update: the adapter is now scheduled to be released in January 2016). Current 20V batteries are available in the 1.3Ah, 1.5Ah, 2.0Ah XR, 3.0Ah, 4.0Ah XR, and 5.0Ah XR varieties.

Charging a Cordless Drill Battery with Laptop Charger Most laptop chargers are rated for 18-20V, which is very suitable for charging an 18V battery. The process is simple.

The XR line of batteries according to DeWalt last 33% longer than the 20v “max” line of batteries of the same size. XR tools and XR batteries are two totally different things. XR tools and batteries are the top of the line and are interchangeable with the “max” line of tools and batteries.

Every one of the cells in an 18v or 20v battery has maximum rating of 4 volts which translates to maximum 20 volts when put together. In essence the manufacturers of the 18v battery makes use of the nominal rating while the manufacturers of the 20v max battery make use of the maximum rating.

DeWalt 18v batteries are compatible with the whole DeWalt XR range, meaning that you could potentially take care of your needs with just two; one in use and one on charge.

Because these new tools will share shelf space with the existing line of DeWalt 18v Li-ion tools, and the new slide-on batteries won’t work with the old post-style tools (and vice versa), the company decided to change the branding to 20v MAX.

DeWalt Batteries: The XR is an updated, higher efficiency battery. For example: you can find a 20v Max 2ah battery and you can find a 20v Max XR 2ah battery. Any 20v tool can use and version of 20v battery.

Yes, our all of our DEWALT 20V batteries and chargers are interchangeable within our DEWALT 20V product line.

With the battery facing you with the terminals in the front, the positive is on the left and the negative is the one in the middle.

The insides of DeWalt 18V vs 20V battery packs are similar. Each battery pack contains 5 cells that are arranged in a series. Each cell has a nominal voltage of 3.6V and a maximum voltage of 4.0V. Now, it is only a matter of whether you are using the nominal voltage or the maximum voltage to name your product.

Well we took two of the biggest tool brand rivals and put their latest 20V and 18V drills to the test. Don’t be fooled by the 20V MAX you don’t get an extra 2 volts, the M18 is also a 20V MAX. Basically fully charged under a no load condition both batteries have 20V. DeWALT decided to market it as a 20V which other manufacturers are also doing now.

So yes, 18V and 20V Max systems have the same amount of voltage power. Let me say it again: 18V batteries and 20V Max batteries are exactly the same voltage. Still, the guts of each battery cell do vary from brand to brand and even within a single brand as technology and chemistry improve.

• DeWalt 18V DC9096 is a NiCad battery. The company claims that the battery has 25% more runtime than regular NiCad batteries in the market. However, a NiCad battery is not very durable, as it may develop battery memory issues and self-discharge. • DeWalt 18V DC9182 is a Li-ion battery.
