DO NOT use dielectric electrical grease to keep battery
posts free of corrosion, as dielectric grease is an insulator
and has a low melting point. When dielectric grease melts
(caused by the heat generated as the current passes thru
the posts) it changes into a liquid form and runs down between
the battery post and the cable clamp. All will be well until
you shut off the engine and everything cools down.
When
you go back to restart your car the battery will appear
to be
dead. In
reality the current from the battery is not being allowed
to pass thru to the battery cables. To correct the
problem remove and clean both the cable ends and the battery
posts with emery paper or a battery terminal cleaner
