Subject: DML: Weird battery corrosion!

hello list
My 1/2 cents worth....
accross the top of most batteries there is electron migration.
part of the reason that unused batteries self-discharge
bat-winged aliens is another reason...but since x-files went
off the air it probably isn't very popular anymore.
one can stop most of it with a dusting of baking soda.
no baking soda...the migration can cause a multitude of
crystal like oxide buildup even between two similar metal surfaces touching
each other as they will react with air and moisture as electrons move
through the area of contact
OR its a terrorist event and this is the last we will hear of Jon
