I periodically need to store my '90 Legacy for periods of 6-9 months, and always disconnect my battery when doing so. Does it make any difference whether I disconnect both positive and negative terminals, or just the negative terminal? (I've seen both alternatives recommended). Also, I normally smear a bit of vaseline on the terminals to prevent corrosion. Is this a good material to use, or is there some other grease which would be better?

 

Thanks,

i would dissconnect both, and also clean the top of the battery. You can get a slight drain of voltage across the two terminals from any stray acid on the surface.

there's a red spray you can get that stop corrosion and protects terminals. it's what we use at the shop, but i don't remember what it's called. i'd imagine that is would be better than vasaline.
