Why Do Battery Terminals Keep Corroding. The presence of corrosion in your cells can weaken your battery power. Its the acid fumes from the battery and moist air that help corrode everything.
Copper once start corroding corrosion does not stop until whole terminals are gone unless you protect them by lubricating them with anti-corrosion compounds like grease vaseline petroleum jelly or silicone. A typical car battery is made up of individual cells with each housing alternating plates of lead and lead coated with lead dioxide submerged in a sulfuric acid solution. Can i just buy new terminals.
It sure did make me mad.
Generally if the corrosion is occurring on the negative terminal your system is probably undercharging. It mixes with other things in the atmosphere under the hood and produces the corrosion you see on the terminals. It can also be caused by an alternator slightly overcharging the car battery over a long period of time. In such a case you should take it to the mechanic for electrical fault tuning.
