Review on High-Capacity Lithium-Ion Replacement Battery With LED Indicator For DEWALT DCB200 DCB204 DCD/DCF/DCG Series Tools - Compatible With Waitley Upgraded DCB206 20V MAX 6.0Ah by Jamal Yang

I am an engineer by trade and have over 50 Dewalt 20v tools and have used a lot of batteries. These batteries once slow charged actually test at 6aH and last the 95% of the run time on the Dewalt batteries. I own 20 of these and over the 5 years they are lasted and continue to hold a charge properly. This being said if I need new 20v battery this will be the brand I get. Hope this helps.Foot Note: I have had 3 of these that came in with a problem, but they were immediately replaced, and their customer support is second to none.
