Why are you worrying about corrosion?Did your drill cease working?In all
electrical installations and transmission and distribution cables, copper
and aluminium is used.Both form a small oxide layer on the surface that
comes in contact with air, that protects the metal beneath.

The contacts of concern in the original thread were battery terminals and
clips. Sulfuric acid and copper produce copper sulphate which can cause
problems. The vasolene trick works- make the contacts first then smear the
vasolene. Side terminal batteries and sealed batteries don't have this
problem.

Vaseline, being a grease (and insulator), impedes current flow, no? Why
are
so many folks recommending a non-conductive grease? (As always, I

I'm
missing something, and have something to learn...)
