How Many Volts and Amps Is the Charger for the Car Charger?

If it is a 12v60ah battery, the charging current must not exceed 2a, and the voltage should be around 13V.

Excessive charging current will reduce battery life. If the current is too large, the chemical reaction inside the battery will be more intense, which is fatal to the battery.

The battery is a vital part of the car. If there is no special condition, the battery does not need to be charged with an external charger.

If the battery loses power, it can be charged with an external charger.

The battery will not lose power under normal conditions. If you haven't driven for a long time, the battery may lose power.

After powering off the car, I think some systems on the car still need power. At that time, the power in the battery will continue to decline.

If you haven't driven for a long time, the generator can't charge the battery, which will affect the battery power loss.

Power loss is quite harmful to the battery. If the battery is in a power loss state for a long time, it will affect the decline of service cycle.

Of course, it is advocated that the young partners must not drive for a long time. If they must not drive for a long time, it is advocated to disconnect the negative pole of the battery.

After the negative pole of the battery is disconnected, the car's anti-theft system may also stop working. At this time, the car's doors and windows must be basically closed.

Not driving for a long time will cause considerable damage not only to the battery, but also to other parts of the car.
