Interesting, I'd wondered about that. The coating of grease might stop the corrosion against the inside of the tube and lube the release from the tube a bit.

Still, probably better if they just don't leak. I'd wondered if alkaline vs lithium makes a difference in the leaking, but it sounds like that's not the case.

I usually use the more expensive Engergizer or Duracels, It doesn't happen often enough for me to notice if it would matter which brand was used.

It's probably just better to change the batteries from time to time, but in something like an LED flashlight, where the use is occasional and the battery life is VERY long, it feels wasteful to get rid of working batteries. I guess maybe yearly or better yet, every other year wouldn't be too bad.
