Black and Decker 12V Ni-Cd A9252 battery convert to bosch 14,4V battery professional (blue series)
I used the top of the old battery housing to mount the converter.
- cut the "tubes" from the screws
- barter wires and make contacts (I used the classic flat 6.3mm male connector - long)
- fill the entire hole with hot glue (to screwing the screw marked in red)
Attach the battery part in the housing of the screwdriver
Screw both printed parts (screw 2,2x9,5) and mount
