They no longer actually produce the batteries for this model. The only info is the following.
(Ace No.(NNN) NNN-NNNN This is a generic battery replacement.
I did some more research on this drill set and found that its been out of production for 6 years and has huge problems with the batteries being very poor quality.
I would suggest getting your batteries rebuilt
These places will rebuild your batteries better than new and they will last longer.
I hope this helps better
