Asked by: DollyP
This adapter enables you to use a 20 volt battery to power an 18 volt tool. The batteries supplied with this kit are relatively small in amps and may be best suited for drills/drivers or other smaller tools. It can power other tools but for a shorter period of time.

what does this kit include ?

Asked by: Harrywm
Charger, adapter, instruction sheet, two batteries. After using the adapter, disconnect the battery. Don't leave the battery connected to it for a long time as the adapter will eventually drain the battery.

hi there, does this battery kit (DEWALT DCA2203C 20-Volt MAX* Battery Adapter Kit for 18-Volt Tools) work for 18-Volt 1/2-in Cordless Impact Wrench (tool only)?

Asked by: Yvonneq
It should work in all the older 18volt applications. We are using it in an 18 volt skilsaw, and it works perfect.

18V-20V Battery Adapter and Charger Kit is rated 3.9 out of 5 by 208.
Rated 2 out of 5 by from Don't hold charge and adapter is hard to pull from I got 2 adapter kits for my tools and it was the worse thing I ever did. Yes the batteries charge fast but do not hold a charge. On a fully charged battery I drilled 8 1/8 holes in a pine board and installed 8 screws and put my drill away. The next day the battery was dead!! I have 4 of the 20v batteries and they all do the same on all my tools. If I charge the batteries and leave them on my bench, they are OK but if put them in a tool and use it for any length of time I know it will be dead the next time I try to use it.Also the adapters are a bear to try to get them out of a tool. Looks like I will be going back to the 18V

Rated 5 out of 5 by from Great Invention, Now I Can Use DeWalt 20V! I am a loyal DeWalt user and over the past 10 years I have spent thousands of dollars on their 18v tools. A little heavy, but they get the job done and they haven't let me down. They have the 20v lithium ion system now that seems like a better product with better batteries and lighter weight. I haven't wanted to throw away my 18v tools just quite yet, but this new adapter lets me use 20v batteries in my 18v tools. When my tools finally die, I can step up to 20v 100%. Thanks DeWalt for not making me throw away all of my tools and letting me continue my trade!

Rated 4 out of 5 by from Good buy overall I've been using these for about a year in my 18V tools, and have been pretty happy with them. Biggest problem might be that tools tend to fall over when set down without the heavy 18V battery. Recently, however the batteries did not seem to fully charge--only enough for short time usage. Called Dewalt Warranty folks today and they are shipping me a new charger at no cost. Makes sense and so I will hope this is the right fix. Have found Dewalt to be cooperative with dealing with customer problems in the past and plan to stick to Yellow Cordless for a while longer. I read where some have reported that the batteries slowly discharge when left in tools and think I have noticed this as well--will experiment further.

Rated 1 out of 5 by from Misleading packaging Was using in our DeWalt drill DC 759 till drill started to smoke. Took it off and put in old battery and it worked fine. Doing research and found on back of package says Do not use with premium DeWALT batteries in DC970 or DC759. (Be nice if it said DC759 18V 1/2" (13MM) CORDLESS COMPACT DRILL/DRIVER) Just looked up the DC759 and found DCA2203C listed, but under the battery it states not to use it with this drill. If it comes up when looking for drill to replace battery, you would assume it goes with the drill. Now to see what other tools I have that will will not work with.

Rated 4 out of 5 by from Price of 18 volt batteries forces me to buy this. I only bought this because it was more affordable than buying a extra conventional 18 V battery. The adapter lets you use this on 18 volt equipment. As a plus any new tools I buy can be the 20 volts one since the 18 volt ones are becoming more scarce. It has worked OK on everything I tried it on, BUT I have not tried completely running the batteries down. Would be 5 stars if it sat straight up instead of at an angle (I have 2 lights that use the 18V battery as a base). Not sure they sell the adapters by themselves but I could use 2 of them since I have no 20 volt tools at this time.

Rated 1 out of 5 by from Go dead fast just sitting in adapter It seems that the adapter is draining the lithium batteries while just sitting in the adapter only, & also cut out (turn off) when fully charged in tough going (start & cut out again & again), don't pack much force to them (not like the original XRP's) just take it slow. Also can't get the adapter out of the tool without removing the battery from the adapter first (extra steps/time). The Chinese have come a long way in a lot of products, I find it unusual this setup ain't right on the mark (for the $). Bought this to Replace four 2 -3 year old XRP's failing. I assumed that the lithium batteries would roast the XRP's. Bought DCA2203C in Dec of 2017 had not tried to use till 3 weeks ago. I don't have a lot of extra time.

Rated 1 out of 5 by from ADAPTER HARD TO REMOVE, BATTERIES ARE JUNK I got two of these packs for Christmas. I am a tall burly guy and I can barely pinch the buttons hard enough to remove the adapter from my drill/driver. (three minute removal time) I thought with two adapters that my needs would be solved because I just left them attached to my different tools. BUT..... The batteries are junk. Out of the five that I got for Christmas and the two that my wife got with her new drill. I can only get one to take and hold a charge. The one working battery will charge in all three chargers, but the other 5 will not. I am very dissatisfied. I have almost exclusively purchased Dewalt tools, but I unless something can be done, I will be switching to another company, away from Dewalt /Stanley/ Black and Decker/ Porter Cable family.

Rated 5 out of 5 by from DeWalt Li Ion Conversion Adapter Great quality device complete with 2 Li Ion batteries, adapter, and Li Ion battery charger that allowed me to upgrade my existing powerful DEWALT drill from the original heavy NiCad 18-Volt batteries to use much lighter weight new technology Li Ion 20-Volt batteries. The new battery adapter and Li Ion batteries easily and quickly snap into place or release, so I have the option of using my old NiCad batteries as hot spares as well. The bit of added battery voltage is good, and is not an issue, but you must use the included Li Ion battery charger to charge new technology Li Ion batteries.
