Reliability of batteries and their damage to equipment

[Ed in Tx]

Almost didn't catch these in time. Couple of Maxell-AA leakers in my Fenix LED L2P flashlight! Had to use a piece of wood dowel to force one of these out. Got to check these things occasionally. Flashlight was still working fine, no indication the batteries were failing. (Scratch Maxell off the list, as a good reliable battery.)
