So here's the battery. Lightly used over the past few years I'd say. I noticed it didn't hold much of a charge and marked the bottom with a piece of tape since it was going bad. One day it finally held no charge at all.
Here's the bottom and model number DW9094.
Once you remove a few torx screws on the top, you're in.
The battery pack is what I expected. A bunch of single cells in series to get to the 14.4 volts needed. The top and bottom of the pack had some cardboard and tape to keep it together as more of a structure.
Once the cardboard is removed, you can see the series hookup for the batteries.
I clipped all of the connections and tested each cell for voltage. I expected maybe a few dead cells and some with a few bits of charge left since it hadn't been that long since I last tried to charge it. But all of the betteries registed no voltage. In a way that makes ssense since this was a series hookup though. If one cell died completely, that would break the circuit and no cells would be getting a charge.
So I decided to keep the cells since it'sl likely some may still be good. Though honestly, probably not good enough to do anything with. The battery case though, that may have some use. I may look in to putting some lithium cells with safety ciruitry in it. There's a lot of space in there to try and use.
