I have had batteries rebuilt, but not DeWalt and been happy with them. I've not heard of counterfeit but I guess it happens. You might look up to see if their is a warranty service location near you and see if they have any deals.
Do it yourself, open them up & check what type of cells are in there. You can order the same type with better mah & assemble it yourself with a soldering iron.
if its lithium battery you can start a big fire , as shown in the online videos, but good recharge cells to refresh your packs have little wire tails preattached on ends for safety
