I recently had a battery corrode in my black
4D cell Mag light. Old style bulb, if that's
relevant.

The 4D mag light by my front door was dead. I
managed to get the tail cap off (two big pipe
wrenches) and find the bottom battery had
corroded. Brand new battery, Endurance, from
Advance Auto Parts. After considerable scrubbing
and sanding, the light works again. I'm leaving it
in peices over night to dry. Then load up with
four Rayovac cells, and a shot of grease on the
tail cap threads.

The 4D mag is my "grab and go" light, in case I
need to go some where in a hurry.

It was only happy coincidence that I found the
corroded battery. Might have been there for
years, if I'd not needed the light for a bulb
test.

Since that time, others have told me that
batteries
corrode only in D cell mags, and typically the
battery next to the tail cap. Has anyone else
had this happen? Is it a common problem?

Have had the same with name-brand cells in AA Mini-Maglites. Only
there, the switch "cookie" at the end that the reflector depresses
when screwed in to turn it on disintegrates, turns to gray powder.
Maglite sells switch kits with the tool to remove the old one and
install the new for a couple of bucks plus shipping, you can get just
about every piece on any of the flashlights from the company as
spares. Prices are pretty reasonable, too. Very nice when the cap
gets chewed up from being dropped or the lens ring gets dinged. Not
enough room in a Mini-Maglite to put a protective plastic sleeve in
around the battery stack. Have had to make up a midget slide-hammer
puller to get batteries out of them after one leaked, really messy
job. Once the switch is out, it's just a tube and regular nylon bore
brushes with some vinegar gets the crap out, then a whirl with some
wet or dry gets the thing shined up for next time.
