Customers appreciate the versatility of the battery charger.

140 customers mention78 positive62 negative

Customers are mixed about the fit of the battery charger. Some mention that it fits well, while others say that it's a very tight fit. The adapter fits easily into their drill, but it'll be difficult to remove the battery. They're small and powerful, but once it''s on it'’s very comfortable and light weight. However, some customers say that the adapter is a horrible fit, and the base is slighly tight on the release tabs. It does not fit the vacuum and hangs down below the plane for the saw.

"...It's also nice that the small 20 volts are smaller and lighter than the 18 volts and pack as much punch...." Read more

"...Just like others report, the adapter fits the tools so tightly that removing it is not as quick and easy as one would like...." Read more

"Fits good, but if you leave batteries in drill, they will drain even without use...." Read more

"The adapter was extremely difficult to attach to my approved drill. It was even more difficult to remove. This is inexcusable...." Read more

Confusion over XR battery designation.
3 Stars
Confusion over XR battery designation.
Product is listed and shown with (2) 20v Max XR batteries. Package received had 20v Max batteries. XR designation not shown on battery label. (Dewalt says it's XR line has 33% greater runtime.) Battery model is DCB203. Don't know if Dewalt's 2.0aH batteries are all the same, XR label, or not, and have not been able to find any documentation on Dewalt's site.What makes me wonder is that I don't know if the batteries were switched out (package came with the side's snap lock open, on the side the batteries were on.If Dewalt changed their labeling on all their 2.0aH batteries to NOT have the XR designation, fine. But, otherwise, it looks like I received a lesser product, than advertised.EDIT: Following my return drop off at Kohl's, I stopped at HD and Lowe's. Their retail products were the same as the one I had received. So, due to Dewalt's advertising of their XR line, Amazon's outdated website pictures and description, and the open packaging, I thought I may have received a product that may have been tampered with and the batteries swapped with a lesser product. I had tried to contact the manufacturer, but their phone lines were closed and chat wasn't working.EDIT #2: Received my replacement kit and these batteries DID have the XR labeling. Called Dewalt and was told conflicting stories.1. XR batteries have a longer run time than non-XR.2. The XR and non-XR labeled batteries are the same.I remember the different (XR vs non-XR) batteries being sold at different prices, in the box stores. If they're the same thing, whomever was paying the premium for the XR line sure was getting ripped off.I've attached pics of the two products shipped by Amazon. First (returned) did not have XR labeled batteries. Replacement set did have XR labeling.With the conflicting stories I got from Dewalt, I'd prefer to have the product WITH the XR labeling.EDIT#3For this particular 2 amp hour size of battery, it looks like the labeling bears the XR designation for batteries produced in Korea. The batteries without the XR label were from Malaysia.

5.0 out of 5 stars Perfect if you have the older 18v tools (and this is on sale)
Reviewed in Canada on December 1, 2020
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?
