Precautions for charging car batteries

Cautomotive Battery Charging Precautions

The car battery is very important for the car. If the battery is dead, the car can not start. And we often listen to the stereo while driving, blowing air conditioning and power windows, these are all need a good battery to power to normal operation. So we usually have to pay attention to the battery in the amount of power, should be timely and regularly charge it to ensure that the power is sufficient, do not lose power work.

One of the following conditions should be charged: the specific gravity of the electrolyte down to less than 1.200; more than 25% of the discharge in winter; more than 50% of the discharge in summer; dim lights; startup powerlessness ;

1, the charger will be connected to the positive cable in the positive post of the battery, and will be connected to the negative cable in the negative post of the battery.

2, in the battery charging at the same time, male car owners are best not to smoke, and do not charge next to oil or flammable special.

3, for one or more batteries in parallel charging, charger voltage should not exceed 16v.

4, for safety reasons, generally on our cars are lead-acid batteries, when charging the last farther away, or wear protective clothing.

5, open the charger, set to the lowest current, and then gradually increase the current until the battery begins to receive current.

6, in the charging of the battery if you find the battery temperature is too high, more than 50 degrees or the battery exhaust vent discharge acid mist, which means that the battery has been bad, can not be used, should stop charging, and replace the new battery.

However, you must pay attention to the following points when charging at home:

1. Lay out the wiring and place the charger, which is best placed on a dry wooden appliance away from the body.

2. Disconnect the battery cable from the car, connect the positive pole of the charger to the positive pole of the battery, and the negative pole to the negative pole of the battery, which is not a maintenance-free battery must be unscrewed from the battery cover, so as to avoid the gas flushing out of the open flame burst

3. Adjust the appropriate current, the charger is generally available on the ammeter, charging is best to observe more than ammeter, charging current is best not to exceed the range of the ammeter The charging current should not be more than half of the range of the ammeter.

4. After charging for a period of time, touch the battery with your hand, a slight temperature is normal, overheating should be adjusted to lower the current.

5. Electrical appliances are fixed-voltage charging, when the battery power loss is serious, just after the beginning of charging to adjust the charging current, as the charging voltage increases, the current will gradually decrease, then should be the second to the high end of the charging current adjustment.
