That possibly explains the mysterious leaking battery problems. I remember that was an issue over twenty five years ago, which taught us not to leave batteries in devices. But then we accepted that they don't leak anymore. Then in the last five years or so, I keep finding gadgets that are destroyed, or almost so, from massive battery leaks. And alkalines don't seem to last very long, even though they are more expensive than they were.
