How you solve that battery corrosion issue inside a maglight tube is pretty simple actually. Grease up the batteries, and the inside of the maglite tube with vaseline, or some other light grease. I use Dow Corning DC33 o ring lubricant. If they leak, open it, and shake em right out.
And use Energizers and not Duracells! Maglites come with Duracells and they won't warranty the lights if the batteries leak and corrode. Almost like they used those junk batteries on purpose just to sell more lights. :mob::lol:
