96 Civic EX

Positive battery terminal keeps building corrosion. I just cleaned it a few weeks back, I never had it build corrosion so fast again. I am wondering if condensation is build under the hood?

Has anyone tried anti corrosion sprays, do they work?

 

How old is the battery?

 

About 2 years old.

 

Never tried any of that. Our batteries don't seem to be producing any.

 

Strange never happened until late last year, battery looks ok the terminals clean up good, it is like a white powder corrosion, I might have to try anti corrosive spray.

 

Warm water would easily remove oxides and make the terminals clean. Grease will keep oxidation away but its a bit messy.

 

do you have the plastic tray between the battery and the actual battery mount tray?

 

It is factory mounted, but if put a tray down the hold down might not fit?

 

misunderstanding. # 4 in the pic

 

i have a tray on all of the cars ive owned and never really had a problem, little to none corrosion. might want to give that a thought.

 

I use a battery anti-corrosion spray and it works great.

 

I use a spray myself, it sprays out a red gunk that covers the battery terminal. It says you can just spray it on, will clean out the corrosion that is there and then protect. I dont know, Mine doesnt corrode, my old mans builds a little ant hill every couple weeks though. We sprayed his, stopped it. I usually hit it with the spray during every oil change. Works great.

My battery is interstate--- no corrosion. (Bout 2 months old)
My old mans is a Napa gold (or whatever their best is) and its nothing but corrosion. His is a good 3+ years old though.

 

Check the cables, mine had corrosion on the terminal end and into the cable. i cut off the corroded part of the cable and put on a new brass terminal end and never had a problem since.

 

Sounds like your battery's being overcharged. But I don't know exactly what to do about an over charging condition. I just know when a battery over charges, it discharges acid.

I suggest doing a full battery and charging system test. Voltmeter to a battery with car off (12.5v - 12.8v), and when the car's on (14.7ish). Once car's on, rev to 3000rpm-4000rpm and check voltage.

(correct me if I am wrong about the voltages please, not too sure about the car on voltage. I don't have my car right now)
If all is fine, battery just may have faulty seals around terminals.
