If you find the car battery electrode wiring at the emergence of some green material, that is, oxide, remember to take away the water in time to wash away, while cleaning the battery terminal, and coated with special grease to protect, to ensure reliable start, extend battery life The If these green oxide is not cleared, it will cause the generator power shortage, so that the battery is in a state of loss, serious will cause the battery early scrapped, or can not beat the car. Battery is most afraid of low temperature, low temperature environment, the battery capacity than the room temperature when the capacitance is much lower. So before the advent of the cold season, should add the battery electrolyte, adjust the proportion of electrolyte.
