I need to find a few of these batteries, actually just the black/orange plastic housings.
A few of mine found the need to jump off my work table and take a dive on the concrete floor, thus shattering the plastic where they screw together.
Several models will work: FSB18, HPB18, etc.
18v slide in style, 24v may also work but will require some additional mods to work properly.
Black & Decker / Firestorm same batteries, even the "high capacity" type use the same case, just different printing.
I don't need the battery cells inside, just the cases, spring, orange clip & screws.
If you have some of these batteries with dead cells, don't throw away the cases, let me know!
