TERMINAL SERVICE
Why battery terminals corrode in Tampa
Every lead-acid battery vents a small amount of hydrogen and acid vapor as it charges. That vapor reacts with the lead posts and copper clamps and leaves behind the crusty buildup you see on top of the battery. Tampa's heat and humidity speed the whole process up, and an overcharging alternator or a battery that's been overfilled makes it worse. White or gray buildup usually means lead sulfate; blue or green usually means the copper clamps themselves are corroding.
Corrosion is an insulator. Even a thin layer adds resistance between the battery and the starter, so the battery can be fully charged and still unable to deliver the current needed to crank the engine. A lot of "my battery is dead" calls are really "my terminals are corroded" calls.
Our service does it properly. We protect your vehicle's settings with a memory saver, disconnect the cables in the safe order, neutralize the acid residue, wire-brush the posts and clamps back to bare metal, inspect the cable ends for corrosion that has wicked up inside the insulation, and replace damaged terminal ends when cleaning alone won't restore a solid connection. Then we reconnect, torque the clamps, apply anti-corrosion protectant and felt washers, and test the battery and charging system to confirm everything is healthy.
