Finding 3LR12 batteries that aren’t sonically welded or glued together with epoxy is the problem I am having!Here's what I intend to do:
Open up the dead batteries, and empty out the dead B cells. Keep the two terminal strips in situ.
Wire up 3 x 4/5A cells in series to the terminal strips. A bit of foam will compensate for the extra length.
An alternative would be to parallel 3 x 18500 cells inside the plastic container, and wire that up.
Where did the package came from, Australia? This is the only country i had packages come from that opens them at customs and checks what is inside, they then put a label that says it was opened by customs, it happens every single time. I would not be surprised if they opened and read letters too.I had massive delays in getting one of these. I seems Customs put a hole in the package and then opened it to see what it was.
