Dewalt Battrery adapter

Yup, they are the same voltage it's just a marketing gimmick using the voltage fresh off the charger.
 
I checked the cost of those adapters, and decided it wasn't worth it for the only two 18V Dewalt tools (drill and impact driver) I have. I like to keep batteries in both so I don't have to keep switching a single battery between the two tools. That would require two adapters, two 20V batteries and a 20V charger; not worth it for two obsolete tools. I retired the Dewalt tools to my condo in Florida where the weak batteries aren't an issue and replaced them with brushless Milwaukee tools. The new tools are way better.
 
I've got several 12v Ni-Cad DeWalt motors, still working, I'm stating to go to 20v Li-lon, 1 drill motor so far.
 
Ive got several 18V Dewalt Tools but instead of messing with an adapter even if they work I plan to just upgrade my entire arsenal to the new 20 V and be done with it. I may even get out of the DeWalt business and switch over to Milwaukee...

So what would the cost estimate be to replace 3 heavier drills, reciprocating saw, 3/8 impact, 6" circular saw, angle grinder, 2 snake lights associated batteries and several chargers?
 
I have bought about 8 of those adapters for my old tools over the last few years . I am well pleased. I buy the 20v 5 size battery Those 5 20v are great they run the tools 5-10 time longer then those old 18v Dewalt xP which were good before needing charging. I sold my old Milwaukee 18v tool because they never made an adapter to go to 20v.
 
The 20V batteries will drain if left in the adapters in the 18v tools.

Don't know why, but they do.

Personally I find the 20V battery adapters awkward. You may not mind.

Wont mention any names but the resident battery expert that we used to have on here got me the adapter for all my old 18 volt craftsman and i now use the 20 LI Dewalt and sure makes them handy
 
I never noticed the adapters draining the batteries, but I started to remove the batteries because the button can get pushed when stored.
 
Adapter works great, had a Dewalt 18v 4 inch grinder that I was disappointed in the performance of. After I put on the adapter and 20v battery I'am very happy with it. The adapter is difficult to remove to change tools.
On the adapter you have to press 2 release buttons together and the springs seem to be extra heavy.
 
(quoted from post at 14:23:56 01/30/21) Anybody use a 20V lithium to the old 18V NiCad adapters? Got a whole bunch of old 18V tools and want to start moving to 20V.
es. I have several Dewalt 18V tools and a couple 20V tools. Bought two adapters and use the 20V batteries in everything. Works fine.
 
Ive been shopping around a lot, the price is reasonable compared to what one gets but to each their own budget and tool choices.

Nice chatting with you

My son and I are switching from dealt and snap on to Milwaukee. He has become very partial to Milwaukee tools. His Milwaukee impact will out work his snap on. Now we all have the same battery,even my wife with her polesaw.
 
Canada here, so things could be different, but after years of dewalt and buying batteries , started looking for something else
found Ridgid, sold among other places at home depot , their tools come with a LIFETIME tool, battery & charger warranty
bought the drill / driver, 2 battery and charger combo tools work as well as the dewalts , time will tell how good the warranty is
you do have to go on-line and register the tools, batteries and charger ser numbers
not sure if they offer the same thing in the USA

I have a Dewalt 1/2 impact 20v with a 5 ah batteries. worked it hard parting out 5 self propelled combine last summer. Took 2 months to do working long days mostly 7 days a week. Put an adapter on impact to step up to 3/4 drive sockets. I worked it hard and it just took it. Handier than a air powered impact. I can't complain about the dewalt at all. The Dewalt replaced a Milwaukee 1/2 18v impact. The Milwaukee was good but battery life was not. I have no experience with a Milwaukee 20v.
 
Yes a different charger is needed and they come in at least 3 different rates of charging, non adjustable. Adapter will not work in charger.
 
I have the Dewalt brand adapters.

Several things:

1. The adapters are difficult to remove once they are clicked in place on the tool. It takes pretty strong fingers to depress the catches and remove them.

2. If I leave the lithium battery in place it will run the battery down over a couple of days. Likely the buck circuit built into it continues to draw current even when not in use.

3. They are supposed to only be using with the 2 amp hour 20 volt batteries. No idea why, no idea if they would work with the bigger ones.

Other than that I like them fine and have quit buying the nicads.
