Perhaps there is a way to rotate the
battery to break it
loose. Hopefully the PFM penetrating oil will do
its thing...


Phil, if you just hog out the contents, then the steel can will be thin
enough to bow in somewhere around its periphery, then to be gripped and
twisted. It will continue to reduce in diameter as you do that until it
finally breaks loose.

Alkalines seldom leak badly like that unless they were left in for half a
decade after dead. They might be zinc-carbons.

In either case, a weak acid like vinegar might help dissolve some of the
attachment. Wouln't use anything stronger, because acids love aluminum
just as much as bases do.
