DeWALT 20V Batteries: XR Li-Ion Technology and Universal Compatibility

A powerful battery is the beating heart of your DeWALT cordless tool. We offer a wide range of DeWALT 20V MAX* batteries, varying in capacity, all based on proven XR Lithium-Ion (Li-Ion) technology . Our batteries are designed to the highest quality standards, with optimized cells and smart electronics for maximum power output and an unprecedentedly long life.

Why choose our DeWALT 20V batteries?

  • Universal Compatibility (18V XR Li-Ion): Every 20V MAX* battery is an 18V XR Li-Ion battery at its core and fits all DeWALT 18V XR Li-Ion tools. This offers unparalleled flexibility and is extremely cost-effective as you only need one battery type for your entire 18V/20V MAX* fleet.
  • Lithium-Ion Technology: Enjoy all the benefits of Li-Ion: no memory effect, minimal self-discharge, and high energy density for maximum productivity and reduced downtime. Internal electronics protect the cells from overcharging, overheating, and deep discharge.
  • Flexvolt Compatibility: The innovative DeWALT FLEXVOLT batteries (which are primarily 54V) can also be used as 18V batteries in all your existing 18V/20V MAX* XR tools. This offers unprecedented flexibility and the possibility to use 'heavy' 54V batteries with a higher capacity in your 18V tools.
  • Various Capacities (Ah): Available in a wide range of Ah ratings (from 2.0Ah to 12.0Ah) to meet every need, from compact jobs to extremely long working days:
    • 2.0Ah - 3.0Ah: Compact and lightweight (e.g. DCB183, DCB182 ), ideal for hand tools and shorter jobs.
    • 4.0Ah - 5.0Ah: Good balance between working time and weight (e.g. DCB184, DCB185 ), all-round use for most tools.
    • 6.0Ah – 12.0Ah: For extremely long working times and the heaviest tools (e.g. DCB186, DCB547, DCB548 ).
  • Rugged and Durable: DeWALT batteries are built to withstand the rigors of daily job sites, featuring impact-resistant housings.

Finding the Right 20V DeWALT Battery for Your Tool

Choosing the right battery for your DeWALT 20V MAX* tool is essential for maximum performance. Universal 18V XR Li-Ion compatibility makes the choice easy, but make sure you choose the right capacity for your specific application.

  • Voltage (V): Your tool is 20V MAX*. Compatible batteries are 18V XR Li-Ion .
  • Capacity (Ah): A higher Ah rating means longer runtime on a single charge. Consider how intensively and for how long you use your tool to choose the ideal capacity.
  • Battery type (XR Li-Ion / FLEXVOLT): All 18V/20V MAX* batteries are Li-Ion. Choose a standard XR Li-Ion battery, or a FLEXVOLT battery if you also have 54V tools.
  • Model number: Always check the original product code or model number of your current battery (e.g., DCB182, DCB184, DCB185, DCB186, DCB189, DCBP034, DCBP518 ) or the tool itself. This ensures correct compatibility.
