Drill itself blew up & was uneconomical to repair, but the battery packs have a bit of life left in them. Not brill but they do still take a fair charge, and the charger unit itself is A1.

The drill was a Bosch GSB 24 VE-2.

Batteries are part no. A09115S, 24 volt, 2 amp hour. Black body, red underside, D-shaped 'bit that goes in the charger' with 3 big and one small terminals. They might fit other Bosch 24 volt tools, don't know.

They're like the 24v battery on this page

There's 2 batteries & the charger.. free to a good home, but they'll be going to the tip in a week or 2 if nobody wants them.

The guy at Derbyshire's mentioned batteries like these are £100 or so new, so might be worth grabbing a hold of these as 'backup' if your tools take the same batts? Seems a shame to lob them.
