At present many say a car battery maintenance free storage battery.Maintenance-free battery compared with the conventional lead-acid batteries do not need to add any liquid, and corrosion of the terminal, wire and body small, overcharge resistance is strong, large starting current, power storage time is long.But the "maintenance" is not to say that it did not need maintenance.
Long-term need not, vehicle battery should be removed or disconnected battery cathode wires.Or every 25 days or so will the vehicle launch time, speed running in about 20 minutes.Otherwise vehicles placed for long, will be hard to start.Battery on disabled, should be enough electricity and often check the battery status, low voltage, to supplement the electricity in time.Cannot be used to make the battery short circuit method to check if there is a electric battery., of course, also can not use metal tools and conductive material in near the battery terminals, so as to avoid metal and battery into the poles, causing a short circuit sparking and damage battery and terminals.Battery vent can't jam, winter will prevent the water seal, otherwise will make the battery internal pressure increases, shell burst accidents.
Replace the battery for cars, must choose in conformity with the specifications of the models.Because of automobile generator capacity is fixed, such as the replacement of large capacity battery, can make the new battery is insufficient, lost electricity for a long time, affect the service life of the battery, the vehicle cannot be started smoothly.Next check car headlights, car lights is closed, the last also check whether the door closed.Another generator fault to solve.The main factors affecting the service life of battery is the loss of electricity.
