Q:My 18 volt batteries have finally played out. I have a DC390 hand saw and DC825 impact drill both 18 volt. What is the largest 20 volt battery can I use with the adapter for my present tools listed above.?
by|Mar 28, 2024
1 Answer
Answer This Question

A:  Most DEWALT 20V batteries work with DCA1820 adapter. However, DCA1820 should not be used with DEWALT 20V premium batteries (DCB200, DCB204, DCB204BT, DCB205) in 18-Volt compact drills DC970, DC759 (instead, use DCB201, DCB203, DCB203BT). The larger amp hour batteries may be too big to fit. they may work, but the door will not close on the battery and adapter.

          This cordless package has allowed me to construct two remote bridges and a 16x40 remote pole barn. I have two extra batteries, one that came with the Dewalt leaf blower I use on remote jobs. These batteries combined last me all day. The impact is super efficient with screws.

          Won’t charge past 2 bars
          From day one these batteries won’t keep a charge and then I realized they’re only charging up to the second bar, it has made me pretty hesitant to make the switch to 20v tools

            Great Drill with Big Battery
            This drill will definitely get the job done, especially with the 5AH battery! Great buy if you do not need a Drill/Impact combo.

              Product has worked great in all my tools so far. My biggest problem is the latches holding the adapter to the tool are way too tight. I have to take the battery off and using two screwdrivers press the lock on one side pry it loose the repeat for the other side. If I could resolve this issue I’d give it an excellent-5.

                Does NOT work with the 6Ah battery
                I bought this adapter and an additional 2Ah,4Ah,6Ah pack of batteries. My 18v circular saw drains batteries faster than any other tool I own. Thought the 6Ah battery in this adapter would be just what I needed, but the 6Ah battery won't attach.

                  Excellent quality and portable too. Used this circular saw actually at home depot for wood that didn't fit in my suv. Just measure what you will need before shopping then use it in the parking lot. Strong and battery life is excellent.

                    How can I give an honest review about using a product when the product comes with not only 1, but 2 DCB207 batteries, WHICH AREN'T COMPATIBLE via the manuals provided. The batteries should have been DCB203's since they would be the closes looking to what was shown on the picture!

                      This combo was a great deal with the 5ah battery. This is my first XR drill and you can feel the power difference compared to the regular Dewalt Max drills. I think three settings for the led light is kind of a funny feature, but hey maybe one day I’ll need to adjust it! The bag now has a sweet rubber “Made in the USA” logo which is cool.
