Thread: Battery failures on illuminated scopes.

Just curious if anyone has experienced battery fairures that have in turn damaged the illumination circuitry in a scope. Particularly CR2032 batteries.
I’ve always removed the batteries prior to long periods of no expected use as an absolute precaution.
Recently, one of the spare batteries I keep aside looked like it had leaked in the packaging so I was glad it wasn’t in the scope. It had corroded quite badly from something at the very least.
Anyone have any clever ideas regarding this?
I presume they have corrosive contents that can discharge and make things go fizz?
