## Overview

The DEWALT 20V MAX Battery Adapter Kit (DCA2203C) transforms most 18V DEWALT tools to run on powerful 20V MAX XR Lithium Ion batteries. This kit includes two 2.0Ah batteries, a fast 12V/20V MAX charger, and an 18V-to-20V adapter, enabling faster charging and longer runtime. Designed for easy installation without tool modifications, it revitalizes legacy tools with modern battery technology, though it excludes certain 18V tool models and requires 20V MAX chargers for optimal use.

## Description

The DEWALT DCA2203C 20V MAX Battery Adapter Kit for 18V Tools allows for use of 20V MAX batteries in most DEWALT 18V Tools. This adapter requires the use of 20V MAX Chargers - this will not fit in DEWALT 18V Chargers. This kit includes two 20V MAX XR Lithium Ion batteries, and 20v charger so you can be ready to convert immediately. Use with DCB201, DCB203, DCB203BT compact batteries. Do not use adapter with premium batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759. Includes: (1) 18V - 20V MAX Adapter, (2) DCB203 20V MAX XR Lithium Ion Batteries (2.0Ah), 12V/20V MAX Charger. WARNING: THE ADAPTER IS NOT COMPATIBLE WITH ALL DeWALT TOOLS. The 20V Max* Li-Ion Battery Pack Adapter for 18V NiCd tools is NOT COMPATIBLE with 18V DeWALT radios, 18V DeWALT nailers, DC020 or DC022 Worklights, nor the DCS370 Bandsaw. For the DC500 Vacuum, the DW074 and DW079 Rotary Lasers, the adapter is functional but the tools’ battery doors will not fully close.

Review: Works Great! - Thank you Dewalt for making this adapter. This is a great adapter that allows you to use the newer 20V battery in your 18V tool. I purchased this to use on my DC725 Hammer Drill/Driver. All you do is plug this adapter into your 18V tool and insert a 20V battery into the adapter. It’s as easy as that. I was a little hesitant to purchase this at first because I read in some reviews where people had to make modifications to get it to work. One reviewer said he had to grind off some tabs (even showed a picture of the modification) to get it to engage into the tool. I didn't find this necessary for my particular application. Another reviewer said he had to grind off some of the material on the release tabs that holds the adapter into the tool (in the case of an 18V battery, these tabs hold that battery in the tool). Again, I didn't find this necessary. I do have to admit that the first time I tried to remove the adapter it didn't appear to want to release. I moved my fingers closer to the edge where the adapter meets the tool and pushed a little harder and it released. I inserted and removed the adapter five more times and now I can remove it with ease -- maybe it needed to work out some burrs leftover from the molding process. Since the Li-Ion battery/adapter combo is lighter than the Ni-Cd battery that came with my drill, the balance of the tool is a little off -- the tool is a little more top heavy, but not a lot and not enough to be annoying. The produce description says that this adapter is not compatible with all 18V tools, but it doesn't list which ones it's not compatible with. Here's what's currently listed in my instruction manual: all 18V radios, 18V nailers, DC020 or DC022 worklights, and the DCS370 Bandsaw. For the DC500 Vacuum, the DW074 and DW079 Rotary Lasers, the adapter is functional but the tool's battery door will not fully close. It also says to not use the premium Dewalt batteries in the DC970 or DC759 drills. If I had anything negative to say about this adapter, it's that I'm still trying to figure out why Dewalt angled the bottom of it. When I sit the tool down, the chuck end of the drill points up in the air about 10 degrees. Then there's the color difference. The yellow used in the battery matches the tool. The Yellow in the adapter is slightly more orange in color, so it doesn't match the tool or battery. But neither of them are deal breakers. I bought this as a kit, so I also received two batteries and a charger. The charger will charge a completely dead battery in about 90 minutes. Overall I'm very happy with this purchase.
Review: Reason to keep my 18v XRP Dewalt tools. - I wanted to upgrade my 18 volt XRP combo set to the 20 volt system because of the lithium batteries were more compact and hopefully they would last longer than a few years. Replacing the 18 volts every few years was not cheap and to keep buying new batteries I might as well invest into the 20 volt system and the the tools have built in lights also which is nice. I thought about selling off my combo set to help pay for a new 20 volt combo set but couldn't find a comparable 20 volt set to my old 18 volt set. My old set had all the tools that I would use myself. The combo 20 volt sets had tools that I would have no or little use for. I tried to piece together a set to compare to what I currently have and it added up to a lot. I am a DIY guy and I do use my tools enough but not enough to justify spending a heap of money to replace them. So I decided to upgrade the battery system and crossed my fingers. Well I am happy I did and for about the same price of buying 18 volt ni-cad batteries I have 20 volt lithiums that hopfully will live longer and gives my tools a new life. If there wasn't a 20 volt conversion kit and I would have to stick with the 18 volt batteries then I might of bit the bullet and switched over to the 20 volts because I was not happy with buying new 18 volts all the time. The kit comes with 2 of Dewalt's smallest battery and I was skeptical on how long run time they would have and it would be a waste of money to get the kit if the batteries drain after a few uses or maybe I will just buy a larger battery to supplement the smaller ones. Well I was pleased to find out after using them they seem to last just as long and maybe longer than my 18 volts and I probably won't need to get a larger battery. It's also nice that you can check the status of the charge by pressing a button instead of testing it on a tool. The adapter with the small battery installed comes out to about the same bulk as the 18 volt installed on a tool. It does have an angle to it installed though, so some tools may not stand up straight sitting on the battery but no big deal. It's also nice that the small 20 volts are smaller and lighter than the 18 volts and pack as much punch. I find that the 2 amp batteries have enough juice for running a circular saw or drill for a weekend warrior. Sure a bigger battery lasts longer, but sometimes you just don't need a bigger battery and a smaller one is nicer. Just depends on your project. The only things that need improvements are the release tabs on the adapter with the battery installed requires two hands to remove the adapter from the tool as you need to get your fingers in there and press firmly on the two tabs. If it is just the adapter and no battery then you can remove the adapter with one hand though unless you have tiny hands. The other thing that needs improvement is that when you slide the battery onto the adapter there is no solid click and you don't know if the battery is locked in. And the last thing is the release button on the battery to release it form the adapter requires two hands also because you have to press and pull as it is not spring loaded and ejects the battery. But I found it easy to release the battery while holding the tool with one hand and squeezing the release on the battery with my other hand and bump the battery on my chest and it pops out. Overall if the battery life holds up and lasts longer in between having to buy new ones then it is well worth it. Right now I am using one 18 volt and the two 20 volt batteries. I am waiting for just an adapter to go on sale so I can get another one so when my 18 volt dies I can have an extra adapter to power two tools with 20 volts.

## Questions & Answers

**Q: Does this adapter drain the battery while it's sitting on the shelf? I read in some reviews that it can drain the battery.**
A: Li-ion batteries have a circuit board (called a PCM) which monitors the voltage of each cell while charging, discharging, or just sitting. If the voltage in any cell goes too low or too high the PCM will not allow charging. The PCM needs a small amount of current to do this job (often this current is pulled from 1 cell but that doesn't really matter). Therefore the battery can potentially become "bricked" if the battery sits on the shelf too long. I try to always fully charge these batteries before placing them into storage and if stored long term recharge every 6 months or so to avoid the battery going to "sleep".

**Q: Does this adapter reduce the voltage going into the drill ?**
A: The working voltage of both the 18v and the 20v battery is 18 volts under load and 20 volts while not under load. Both batteries are essentially the same voltage under both conditions.

**Q: Does with work with the larger batteries even though description says compact batteries only?**
A: When I read this specific limitation, "Do not use adapter with premium batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759." it is written in a way that you should not use premium batteries with the two compact drills mention (DC970 & DC759). I have used this adapter with 2 AH, 3 AH, and 5 AH batteries. Each different size battery provides power to the tool and does not appear to affect the function. It is worth mentioning that I do not own the two compact drills noted above. Also, the adapter will have issues with the 18v circular saw. Even with the slimmest 2 AH battery pack, the circular saw will not be able to cut at its full depth due to the battery pack making contact with the surface of the wood. This will only affect you if you plan to make cuts longer than the base (shoe) of the circular saw at full depth.

**Q: Will these batteries & adapter work with my dw959 drill and dw936 circular saw?**
A: As long as it takes Ni cad batteries it will work. The only down fall of this adapter is that u can't leave your batteries plugged on the tool. Someone in the adapter drains the lithium batteries. Other than that it's a good product

### ⭐⭐⭐⭐⭐ New life for old 18V tools
*by G***E on July 26, 2025*

Still use my 18v Dewalt tool set. The 18v batteries were getting harder to find and expensive for OEM. So, decided to try this adapter kit. Work great with a circular saw and the drill so far. Tools spin right up to full power again. Batteries are small and lightweight. Easy to snap in to charge or use. Great way to extend the life of some tools with a better battery source.
