DEWALT 20V MAX Battery Adapter Kit, 18V to 20V, 2 Batteries and Charger Included (DCA2203C)

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.

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.

Review of DEWALT DCA2203C 20-Volt MAX Battery Adapter Kit for 18-Volt Tools. Have older DC759KA 18v Compact Drill Driver, still like brand new. Came with hard case for transporting/storing drill driver, charger & spare battery pack. Still today a very nice 1/2 drill driver. Was time to purchase replacement cells of the original 18V NiCads. Thought I would upgrade to this new Li-Ion package. Would work well for those who do not store or transport drill driver in hard case. 3 issues that I ran into with this conversion kit. 1. Does not cover entire bottom of old style larger NiCad packs, did not like the large open areas on bottom. 2. With conversion kit in place, although lighter, not a good balance for my Dewalt drill driver. Being smaller in design, makes drill top heavy when placing on countertop, easily tips over. Although heavier, the original NiCad design provides perfect balance when setting drill driver down with chuck facing up. Never has tipped over and is perfectly balanced. 3. All Dewalt 20v cells are actually 18v cells, so after looking at specs, nothing gained between NiCads vs the 20v cells included in this package. It is a great product if you intend to take advantage of Li-Ion cells vs NiCads. In my case, I prefer the original balance of the drill, the ability to stand driver up without a balance problem. Fortunately Dewalt still makes the original NiCads so I will return this kit and purchase the old style NiCads. Yes they are more to keep an eye on when compared to the newer Li-Ions. Trade off is the NiCads will start to delete gradually when using the drill. Thing I do not like about Li-Ion is it gives no warning when depleting unless you purchase cells with the LED indicators. Honestly, did not like the feel of this conversion kit on my DC759KA which is a 1/2" chuck, with 2 speeds of power. With good NiCads, the torque is the same as the Li-Ion cells. This kit would work well in the smaller compact 18v drill drivers. My DC759KA was made in 2005 and although called compact, is more like a full size with considerable more torque than todays smaller motor and sized Dewalts. Also purchased the 20V compact kit which is for smaller projects where a smaller lower capability unit is desired. I will still use the old full size compact for larger jobs.

Bought this during Black Friday week (119cad). It was a nice price for the package and I didn’t have to buy knock offs. I doubt I would have purchased this at the current 179cad. I have all of these from previous purchases and I thinking I could use two more 2AH batteries and at this price I decided to get the package as it was close to the price of the two batteries alone. This arrived in a single plastic factory vacuum sealed package so it was not hobbled together by a vendor and nor was it old stock. The batteries have 2020 year stamp so I was quite pleased given the price. Adapter Basically I wanted another 18 to 20v adapter so I can just leave them on the two 18v tools I have not replaced. The original adapter can be difficult to remove as mentioned in many reviews however I found this one alittle easier some reason (my original has a 2016 year stamp and this one 2019). 2AH batteries I am invested in 2 cordless tool lines Dewalt (20v and flexvolt) and Bosch 12V. I like to size and weight of the Bosch 12V drill/drivers for most wood and DIY work and use the Dewalt versions for more HD tasks. I like using the 2AH batteries on my drill and driver despite having 4, 5 and 12 AH available as I often don’t need the run time. In my environment the big batteries have their place on high drain tools or for extended jobs. My drill, driver, oscillating saw, LED work lights and old 18v tools are happy with theses batteries. Charger. Comes with the BCD112 which is the slower 2 amp charger which is how I guess they lowered their cost on this package. I have the BCD115 (4 amp) and BCD116 (6 amp) which were “standard” in my other kits. Not sure why Dewalt has to have so many different “standard” kit chargers. Why not just the one faster one for all?

dura como igual o mas que las pilas viejas pero son mas ligeras y se cargan mas rápido una excelente manera de mantener vivos tus taladros de 18 volts, las pilas tienen una vida util poco corta ya al año de funcionamiento tuve que comprar baterías de nuevo le dejo 4 estrellas porque si funcionan pero antes del año empezaron a perder muy rapido la carga

This product works well but would get the 4ah batteries instead of the 2ah cause they don’t last as long! I bought this to convert by Dewalt sawsall from 18 to 20 volt. Doesn’t take long to charge batteries

As described, these smaller & lighter batteries last as long as an 18volt XRP. I bought this kit to try the lithium batteries on my many 18V tools prior to buying more of the larger 20V lithium batteries. I have well over 20 of the older style 18V Dewalt tools and am not yet ready to spend the 4000$ to replace them all with Lithium tools. The main issue I have with the adapter portion is that it is not easily removable from the tool. In colder temperatures, you'll have to leave the adapter in the tool or risk breaking it or hurting yourself. It is easier to remove in warm weather, but still not a smooth process. I like it, but unfortunately, can't use it unless I keep it in only one of the 20 tools I would like to have used it on. I am not going to buy 20 plus adapters! Dewalt should definitely make this adapter more user friendly. As a contractor, I just don't have the time to fiddle with it and will likely just purchase more 18V batteries for now.

It was a good deal
