Rated 1 out of 5 by from 18v to 20V upgrade I bought the upgrade kit with adaptor over three months ago. I charged the lithium batteries. Now I finally go to use it and it doesn’t work, a couple times I got power to my drill but intermittent,as if the connection is weak. What a headache. So now it’s back Dewalt to try and understand why the issue!! I’m very disappointed with the product.

Rated 5 out of 5 by from Works well. This fits on all of my old 18V XRP tools just fine. I have the hammer drill, impact driver, circular saw, grinder, reciprocating saw, 1/2" impact, and flex light and it works great in all of them. My 90 degree drill won't accept the adapter but I do not think it was ever in an XRP offering and is my only Dewalt cordless tool that is not XRP. The adapter is a little difficult to remove in some tools and is almost impossible to remove if you leave the battery in so it is best to remove the battery first. I just started replacing all of my XRP tools so I only plan on using this while I do that over the next year or so. I am using the DCB205 batteries and the run time seems like about 4 of my old batteries combined, maybe more. It looks odd on the tools and sits at an odd angle but works well so far. None of the larger batteries (6.0ah plus) fit the adapter but the run time is long enough with the DCB205 where having a spare battery would run a tool for a full work day anyway. I noticed a significant improvement in power even over my newer XRP batteries in all of my tools and have not seen any drawbacks besides making the tool overall length longer which makes fitting in tight areas a bit more difficult.

Rated 1 out of 5 by from Another Dewalt dud I've had this kit for about a week. Charged both batteries before using" and each tool ran ok the first (short) time I ran them. The next day, one tool was totally dead and the other ran a very short time. After reading a review, I see that leaving the battery in the adapter drains it. This makes the kit useless in my opinion. The last regular 18v batteries I bought had a short life. So this makes two purchases in a row that lead to disappointment. As another reviewer mentioned, they also don't fit the tools well. Darn near impossible to remove. I don't suspect Dewalt will do anything about this.

Rated 3 out of 5 by from Needs warning to not store battery in adapter I bought this to enable me to continue using some of the older tools without buying more of the older style batteries. For that, it works great. However, it does not have any warning the connecting the battery to the adapter will drain the battery when not used. This is a surprise. Now I always remove the battery when finished using the adapter. I think this is a surprise and a negative for this product since leaving the battery attached to the tools does not drain the batteries.
