Charge: pay close attention to the overcharge of the battery or the long term loss of electricity. Overcharging will cause the hardening of the active material of the plate and the electrolyte to accelerate evaporation, resulting in irreversible destruction. Lose electricity plate curing. Therefore, the vehicle mainly ensures that the voltage of the mediator can not be too high or too low.
The battery has a certain service life and will be replaced in a certain period. The same order should be followed in the replacement, but when the electrode line is connected, the order is the opposite, the positive pole is first followed, and then the negative electrode is then connected.
When the meter pointer shows that the storage capacity is insufficient, it should be recharged in time. The storage capacity of the battery can be reflected on the dashboard. Sometimes the power is not enough on the road, and the engine can't start again. As a temporary measure, it can help other vehicles, and use the battery on their vehicles to start the vehicle, and connect the negative pole and the negative pole of the two batteries. The positive pole is connected with the positive pole.
When starting a car, uninterrupted use of the starting opportunity causes the battery to be damaged by excessive discharge. The correct method of operation is that the total time of each engine is not more than 5 seconds, and the interval time is not less than 15 seconds again. The cause should be found in other aspects, such as circuit, ignition coil, or oil road, in the case of multiple start - up without the car.
Often check the parts of the circuit where there is no aging or short circuit. Prevent the battery from being decommissioned in advance because of excessive discharge.
Hydrometer: the installation of the maintenance free battery can indicate the storage electric state of the battery and the height of the liquid level of the electrolyte. When the proportion of gauge of eye is green, indicating that the charge is enough, the battery is normal; when the eye is black or green indicating little, indicating the battery needs charging; when the indicator light yellow eye display, indicating the battery internal fault, the need for repair or replacement.
