Leaking & stuck batteries in flashlights

In my very expensive brand flashlight, a battery had leaked and can not be rauszubekommen. Despite fumble, scratch, screwdriver, nail file, etc., the thing was stuck.

In my anger or desperation, I put the flashlight almost to the head in hot water and schwupp, after a short time, the batteries fluttered out. The flashlight goes off again and there is no damage left.

I was happy and think that may be synonymous with other flashlights - certainly not all?
