Friends:
Regardless of what material you prefer to protect battery posts, I don't
recommend applying it until after the connection is torqued. The cable
ends and the terminals need to be wire brushed immediately prior to
assembly. We had to dis-assemble a set of batteries and move them for 48
hours. The terminals had been cleaned the previous day. After sitting
under a cover for 48 hours, when re-assembled, the terminals had enough
invisible corrosion to cause a significant inability to charge
correctly. After cleaning the terminals the problem was corrected. We use
a small Makita grinder with a wire brush. This does require care to avoid
arcing and brushing away knuckle skin.
Napa Auto has a spray-on terminal protectant that skins over nicely, making
less of a mess when checking electrolyte levels. It also has an attractive
cranberry color.

I was just picking up on where everybody is located. The cold weather boys
like vaseline, and obviously you warm weather folks need the grease.
I think this affects the battery sizing debate too: if I size a battery
for 4 days storage, it only has 2 or 3 days of storage in really cold weather.
