Alot of people have older Nicad battery tools that have been on the way out battery wise, this adapter allows you to utilize newer 20volt batteries and bring new life to those tools that would have been otherwise no longer useful. It fits fine on most tools, looks a little different but if your looking for perfection you wouldnt be buying a money saving device to kickstart old tools anyway. But it allows those old tools to benefit from litium ion battery power and technology.

It does function, but the top doesn’t fit all the tools that are older. So, trying to release it from your tools can be very difficult.

the adaptor works as it should, i’m happy with it’s performance. however I have found that when the tool is not being used you have to remove battery from the adaptor so the battery will not lose its charge. the adaptor puts a slight draw on the battery and over several days it will deplete charge from the battery.

If have 18V cordless tools that are still in fairly good condition and transition into the 20v toolslike it is a relatively cheaper way to transition. I have a few 20v tools. Now I have the option of using both the 18v and 20v…The adapter works great with the newer 20v batteries…Would definitely recommend the purchase.

Although there are side clips allowing you to remove the adapter from the tool, it is VERY difficult to remove it. So much so that you probably won’t want to remove it and just buy another. That is what happened to me as I just bought my second one because the first one was too hard to remove.

Only reason no 5* rating is the new Lithium batteries (or this new adapter) cause my trouble lights to flicker (or pulse) about once a second … I am working with DeWalt on this … The Home Depot order and Pick Up process went smoothly and I am VERY pleased with that ! Thank You !

I am very happy with the lithium battery 18 volt adapter. It is awesome to still use my old 18 volt tools because they still work great.
