Battery terminals produce a chemical that causes the transmission of current to be blocked is called battery terminal corrosion.
The chemical substance inside the filled battery leaks or forms on the surface of the battery terminals due to various reasons.
(1) Overfilling of the battery, when adding water to the battery it must not exceed the level of the lead plates, the part that exceeds the level will overflow and corrode the metal terminals.
(2) electrolyte leakage, due to prolonged use of the lack of hair maintenance leads to electrolyte leakage in the battery, the leakage of electrolyte and terminal metal reaction leads to corrosion.
(3) Chemical reaction with copper clips
Copper clamps in the charging process copper clamps are not easy to corrode, but when the current through the easy production of copper sulfate, easy to corrode with airborne material terminals.
(4) overcharging, when the battery charging more than the battery capacity of the excess power will act on the electrolyte to produce hydrogen and oxygen and metal electrode reaction.
(5) Hydrogen leakage, the battery charging and discharging system in the acid and lead reaction to release hydrogen, hydrogen leakage will make the substance with the air reaction leads to corrosion of battery terminals.
(6) Voltage fluctuation, voltage fluctuation will give the lead plate pressure leads to the lead plate is pierced, resulting in lead sulfate covering the terminals, resulting in the loss of charging capacity.
(1) Antiseptic, easily available in various repair stores, spray the battery terminals with antiseptic so that the terminals are not prone to chemical reactions.
(2) charger, to ensure that the battery charging to meet the effective guarantee of terminal corrosion, undercharging will lead to negative terminal corrosion charging overfull will lead to positive terminal corrosion, the use of power chargers to ensure the quality of battery charging.
(3) Replacement of lithium batteries, lead battery terminals are generally corrosive phenomenon, if you can choose to replace the lithium battery can effectively prevent terminal corrosion.
(4) Copper terminals, copper terminals are composed of tin-copper alloy with better energizing efficiency.
(5) regular maintenance, regular vehicle maintenance can effectively prevent vehicle accidents, regular vehicle care can effectively prevent battery liquid leakage.
(6) Mineral grease, dielectric grease on the terminals coated with grease material makes the reaction more difficult to prevent corrosion effect.
Soda, terminal corrosion can be eliminated when the corrosion on the terminals clean terminals can be a short-term repair of the battery’s power supply capacity, simply use soda poured in the place of corrosion after a period of time with a steel brush to brush away can be
Battery terminal corrosion is a normal phenomenon, terminal corrosion is the chemical reaction of the water-filled battery, the resulting chemical substances block the transmission of current, after the removal of corrosive substances can be used normally.
Terminals are connected to the car’s power supply system, terminal corrosion will lead to current transmission limitations resulting in the car can not start or car algorithm error.
Battery terminal corrosion leads to the current cannot be effectively transmitted, electronic equipment cannot effectively run the more sensitive electronic equipment will be damaged.
