You need to know how to charge the car battery before buy a car.

The car starting battery usually need to 20 hours to recharge.

When cars run through the generator to the battery supply electricity, but the battery is serious deficient electric need to replenish the electricity, the amount of charge on the car itself completely not enough, can only use a portable charger to recharge the battery, automobile starting batteries for 20 hours.

12 v60ah, for example, charging ways: by charging in the form of constant voltage current limiting constant voltage 14.8 V, 15 a charging current limiting 16 hours to 4 hours 3 a constant current charge, a total of 20 hours.

Battery fully charged can be judged according to the following phenomenon, or watch magic eye for the green is full of electricity:

1) battery produced a large number of air bubbles, both "boiling" phenomenon;

2) voltage of up to a maximum and no longer rise in two hours;

3) electrolyte rose to the highest level, and no longer rise in two hours.

May cause of the car battery without electricity:

1, in the car after the machine stops running, and high-power appliances such as air conditioning, music machine forget to close, will make the battery severely deficient of electricity, never so use for a long time.

2, the battery life does not save the electricity or the end of self-discharge.

Automobile starting batteries normally takes 20 hours.When cars run through the generator to the battery supply electricity, but the battery is serious deficient electric need to replenish the electricity, the amount of charge on the car itself completely not enough, can only use a portable charger to recharge the battery, automobile starting batteries for 20 hours.

Depending on degree of kui electric battery and charger charging current.

For example: empty battery power, in itself, 1/10 of the charging current capacity, can charge about 10 hours, that is to say, the capacity of 100 ah battery, with 10 a charging current, can charge about 10 hours.

A, the action of accumulator

1, the battery in the vehicle has not started, as to provide electricity, in-car entertainment, lighting, glass elevator, etc.Note: do not use electrical equipment for a long time after flameout, otherwise it will cause the battery loss, cannot be started.

2, the starter when the starter.

Second, the battery failure before sign

1, the start difficult

2, the instrument malfunction indicator

3, the headlight dimming

Third, check the battery in winter

1, car battery voltage is 12 v, in addition to professional electric current cannot be detected, commonly used multimeter can detect the voltage, suggest check the voltage to detect vehicles overnight results are stable.

2, in the vehicle before starting, please don't seats, steering wheel heat, rearview mirror heating, mist, and other functions

3, if the battery have use fixed number of year for 2 years, is the need to check more in front of the approaching winter.

4, in a short period of time for frequent lighter, if did not start in five seconds, then wait for 30 seconds and try again, and close all electric equipment.

Three consecutive didn't play on fire are waiting for 3 minutes and try again.Lighter moment battery discharge current is big, if continue to discharge will only cause battery faster low, more difficult to start.

5, try to contact with friends, take note was negative, the other vehicles start state electricity, 4 s shop or contact with the insurance company.

Battery is serious deficient electric need to replenish the electricity, the amount of charge on the car itself is completely not enough, can only use a portable charger to recharge the battery, automobile starting batteries for 20 hours.Such as 12 v60ah charging ways: using constant voltage current-limiting charging in the form of constant voltage 14.8 V, 15 a charging current limiting 16 hours to 4 hours 3 a constant current charge, a total of 20 hours.Battery fully charged can be judged according to the following phenomena: 1) inside the battery produces a large number of bubbles, both "boiling" phenomenon;2) voltage of up to a maximum and no longer rise in two hours;3) electrolyte rose to the highest level, and no longer rise in two hours.Or watch magic eye, full charge state determined from magic eye is green.
