All batteries sealed or not vent some place out the side or caps on top and those acid fumes cause a corrosion. As said baking soda mix can clean it all off but never get it or aerosol cleaners inside the battery cells. Corrosion will return again after a while if the battery has a leaking post or bad cell venting more fumes out. NAPA and other places carry a handy aerosol cleaner that works well and changes colors telling you when you have all the acid neutralized and then rinse it off with water. They also have a brush or spray on red stuff in a can to help seal out corrosion on battery posts and cable terminals after brushing them clean. Coke works too as a cleaner because of the soda in it to neutralize acid. Auto supplies also have little felt treated washers to put on posts that help retard corrosion. I've used the white lithium grease on posts for years because it helps seal out air for a while so things won't corrode as fast and then spray the protector sealer over posts and mounting brackets also but don't spray it on battery caps sealing those because it still has to vent.

JIM After you clean the battery posts and cables and battery, put a couple pennies on top of battery, they will collect the corrosion,when they get covered replace them, problem solved Ken

You might want to make sure that the alternator is not overcharging the batteries.

it would have been nice if you mentioned that in youre first post must be the caps are leaking a little bit here in the northeast all batteries do it i think from the freeze and thaw.

You can also buy battery cleaner and battery sealer/protectant in little aerosol cans. Spray the cleaner on all the affected parts, let it sit a minute or two and brush it off with a wire brush. Put everything back together and spray with sealer. The sealer is much less messy than grease.

thats corrosion sulferic acid of the battery causes it a wire brush will remove it there isnt much to do to keep it from coming back a trick is to clean the past and terminals then smear grease on them that will delay it awhile moister plays apart in it also thats why the grease helps maybe youre battery is leaking a very small amount im not sure i see youre from n.m. so you probably dont have too much of a moister problem there.

Jim, I'm not an expert by any means, but this isn't a fungus. I believe it's lead sulfate corrosion and you can get rid of it by brushing with some baking soda dissolved in warm water. Dry the terminals and clamps after you're finished and coat them with some vaseline; this should prevent it from happening again. Bill

Don't let any of the baking soda solution get into the battery. It will neutralize the acid and weaken the battery. Its very likely that the battery posts are not sealed to the cover and so acid is splashing out there. If it is, then the baking soda can get into those cells and damage them.
