battery terminal corrosion

[Speck]

Is there any way to keep the positive poles of my batteries from corroding so bad? I have an on board charger/maintainer but I've noticed when it is plugged in, alot of corrosion collects on the terminals. Do they make a product that will stop this? Is there anything else I can do to correct it? Thanks

I have had good luck with these. http://www.autozone.com/servlet/UiBr...ELYX%7C%7Etrue

I've never had corrosion problems on my boat batteries but I keep the felt pads on all of my vehicles. Usually replace 'em only when replacing batteries.

Clean it with bakeing soda then coat with petrolium jelly. Its messy but works. I do see some cars come through the shop with a penny under each terminal and none of those are corroded. Havent tried that.

When they are new or real clean they make a spray coating like thin paint that works well. I also use 100% silicon spray on all my electrical connections and plugs and that helps too.

I think most auto parts stores would have this including Walmart.

When I got mine new from the dealer they had put some type of silicon on them and I seem to have no problems at all.

Speck go to your local parts store and buy a tube of die-electric grease clean the terminal with battery clearner also from the parts store,then cote them with the grease and reassemble.Its specifically formulated for electrial connections.I use it on all connections at the shop and it works about the best.:D

It's called Battery Protectant and it works great. If you have an older battery, clean the posts and the insides of the clamps with a special tool you can find at an auto parts store, then spray the protectant on the posts and clamps and your battery will last longer.

All of the products recommended will help but the bottom line is that when the batteries get older the seal around the post will leak vapor when heated (by charging or loaded use) and this is what causes the corrosion and the only way to stop it that I have found is to have the battery rebuilt or replaced.
