The rechargeable battery died on my electric toothbrush - after a few minutes looking at prices online, I reached for the Dremel!
A 4x AAA battery holder and some hot melt glue, and its working again, the difficulty arises from the 4x 1/3 AA battery assembly was as if a core to the pick up coil for the no leads charging stand.
Unfortunately I neglected to refit the scrap battery, so the pick up coil no longer has a big fat shorted turn in the middle of it - when I stood it in the charging stand, the charge LED looked a bit over-bright.
I could just take out the AAA cells and put them in a regular charger, but I kind of like the convenience of the charging stand.
How bad can it be?!
Thanks for any advice.
