One great thing about Dewalt is that most of there products come with a 3 year warranty. If you have tried all of these fixes and the adapter system is still not working, you should reach out to Dewalt at: 1-80. Hard to connect/disconnect battery from adapter.Dewalt’s switch from 18v to 20v battery system.Sometimes the fix is much easier then you would expect.
If that is the case for you, be sure to run through the checklist before reaching out to Dewalt. There are many different reasons why your Dewalt 18 volt to 20 volt adapter may not be working. That means you have to have a 20v charger. Or is the tool the issue?Īnother common complaint that I hear is that you cannot use an 18v charger. Remember this is a 3 part system: the adapter, the battery and the power tool. If you are positive you have done everything correct when using the adapter but it still does not work, it is time to look elsewhere. You may be able to adjust the angle of the tool to fit but sometimes this can significantly limit your project. The height of the adapter cannot be changed. Unfortunately there is not much you can do about this issue. Therefore they will not fit on the adapter. Anything above 5 ah has an extra seam on the battery.
I have found the adapter only works for 5 ah and below. The premium and FLEXVOLT batteries are higher ah (ampere hour). It will not work on the newer 20v or 60v FLEXVOLT series.ĭewalt also states on there website when purchasing the adapter: “Do not use with Premium Batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759 (use DCB201, DCB203, DCB203BT)” When purchasing this adapter from Dewalt they make it clear that it only works on the 20v max batteries. Unfortunately this adapter does not fit for all of the new batteries that Dewalt has released. Battery does not fitĪnother fairly common complaint is that the battery does not fit. As you press the button you should be able to slide the battery right off the adapter. To disconnect the battery from the adapter you must press this same button. If this is not done properly the connection will not be strong enough for the tool to work. If it is done right, you should hear an audible click, this will indicate that the battery is on the adapter properly. You MUST press this button when sliding the battery down the adapter. This is the same button you press to remove the battery from a tool. As seen in the picture, there is a yellow and black button on the battery (color will vary depending on battery).
