Good idea to use anticorrosion battery terminal products?

I have looked at a couple of different Prius batteries and have not found any evidence of corrosion. Didn't see any evidence of any product on the terminals either. Wouldn't hurt to use either product, your call.

 

I don't believe this is necessary since those products are intended for situations where battery acid is leaking and causing terminal corrosion.

 

There should be less need as the battery is externally vented, so corrosive gases should not be present at the posts.

 

Smear some Vaseline on them if you want.

Not the be all and end all, but I'll look at how the car came from the factory, for guidance. The terminals on our 12 volt look clean/bare. That's actually a replacement battery, installed by the dealership at time of sale. And around 3.5 years later it looks about the same, no sign of corrosion.

So, I'd be inclined to not add any grease. If I had the battery out, or was replacing it, I'd run a wire brush or sandpaper over the posts and inside of the connection collars, that's about it.
