Battery Terminal Corrosion

7510 Views 9 Replies 7 Participants Last post by  MardiGras
I keep getting corrosion on the battery terminal. I also feel like this may be affecting the performance of the battery, since the car feels a little sluggish.

What's recommended here? Should I replace the terminal wire pierce and clean the battery? How can I stop this from happening?

Thanks in advance.

I had the same problem on my 2007 Si. First clean everything with CRC battery cleaner. Then hose it off with water. I would then remove both cables and further clean the battery posts and cables with a brush. Then inspect for pitting on the cables. The battery acid will slowly eat way the terminal and when I went to install a new battery the terminal disintegrated. If yours are in good shape, get CRC terminal protection.

The positive cable is $70 for an OEM from hondasuperstoreparts.com. I went the cheap route and purchased a nice marine style clamp for around $3. If you have access to a dremel tool, you can remove the thin clamp Honda provides. Put some dielectric grease on everything and you are good to go. I have had no problems since I did this.
