Have you got some dirt or oil/grease on the battery posts? That's what
it
sounds like to me.

So when is grease on the terminals bad ??

When it gets between the battery post and the clamp.

Most user/workshop manuals I've seen, advise a smear of petroleum jelly on
the battery posts to prevent a buildup of corrosion under the clamps.

Over the years, I've had various vehicles that seemed incapable of
containing their engine oil - once or twice the battery also got drenched,
apparently without any adverse effects.
