Dewalt charger dw9116 got wet while charging and won't charge any more

High Performance Current Mode Controller doesn't work for you in the charger. According to the link, scheme.http://kazus.ru/forums/attachment.php?attachmentid=51161&d=1377505983

What I do know is that some NiCd 12V Black decker batteries that look similar to the dewalt ones they are charged by the dewalt charger.
But there are 12V Nicd black and decker batteries that they can not be charged due to an extra plastic edge that does not allow to be charged by the dewalt charger.
Now if you do have the dewalt lithium 36V charger and if the black and decker battery is a 36V lithium one and can not be charged due to a plastic edge then I would recommend to risk to destroy the plastic edge in order the black and decker battery to be charged.

May read instructions and see if charger is compatible of charging the two types of batteries you are charging ,,,,I have 32 dewalt 18v dc9096 batteries and 1d dewalt 18v dc9099 battery

Your problem states you have a Makita tool and your question is about a Dewalt lithium battery. In either case if the battery won't take a charge or if the charger is showing the battery is defective the only fix is to replace the battery. Some causes for defective batteries or batteries that won't take a charge are bad cells in the battery, bad or shorted IC board in hte battery, broken or burnt connections between the many cells or between the cells and IC board or even bad or old cells that will no longer charge up. The time and effort needed to find out what the problem is then finding another battery to scavenge parts from (individual battery parts are not available) is never worth the cost of just buying another battery and going back to work with the tool(s).

The problem is your batteries are either over heating or worn out. You might also have a problem with the charger but you'll need Dewalt tech support to determine if it's good or bad.
The first thing to do is clean the contacts. Use a white plastic pencil eraser and clean all the contacts you can reach. If there are any contact you can reach with the eraser use a Q-tip that is just damp (not wet) with rubbing alcohol to clean them.
Discharge your batteries completely then put them in the freezer for 8-24 hours. Take the batteries out of the freezer and let the set 24-48 hours after that put them on the charger, they'll either charge or you need new batteries (more likely) or a charger.

Here is a link to a number of 220v chargers that will work for you. You can, of course, use the 110v charger with a down converter.

It means there is too high or too low a voltage coming into the charger. Check your chord.

I had the exact same problem. After using the necessary security bit to crack mine open, I found that the large capacitor inside had come loose and needed to be re-soldered.

That fixed my charger.

Go to Dewaltservicenet.com and in the middle of the page at the bottom find the looking for manual box. Type in your model number and it will take you to a page click in the owners manual and download it from there it is 5 pages long. If I have helped you would you please rate my solution accordingly and thank you.
