Are DEWALT batteries interchangeable with Mellif tools?

The compatibility of the battery depends on the voltage. Both the battery and tool must operate on the same voltage. 

Flexvolt batteries are an exception. Flexvolt batteries are compatible with Dewalt 60v and 20v tools, and can be charged by 60v or 20v Dewalt chargers. Flexvolt tools require Flexvolt batteries to operate and are not compatible with Dewalt 20v batteries. 

In Mellif, you can find tools that DEWALT doesn’t make but fit your DEWALT 20v Max Batteries. Built-in protection as well. You can use the batteries on Mellif tools with confidence. What’s more, Mellif provides 12 months warranty for all the products. You can simply easy to get the replacement by an email or phone call if any quality issues.
