## 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

    Keeps older tools working hard
  

*by T***. on Reviewed in the United States on 29 May 2023*

I haven’t been able to obtain the original-style batteries for several years, so this was really nice to see. These particular batteries are admittedly not of high capacity, but work fine for my purposes; larger ones are available that are compatible with this charger to consider in the future.Just like others report, the adapter fits the tools so tightly that removing it is not as quick and easy as one would like. It would be better to have an adapter on every tool and just change out the batteries (which slide on and off nicely). The LED “fuel gauge” function built into every battery is very convenient.>>>>>>> Do not forget to remove all the batteries from the tools during storage to prevent slow power drain. By doing this, a charged battery should always be ready and waiting.<<<<<<<

    Perfect if you have the older 18v tools (and this is on sale)
  

*by B***A on Reviewed in Canada on 1 December 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.AdapterBasically 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 batteriesI 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?
