Generally, the battery of a car will be dead after about two months. If the battery is dead, it will affect the start of the car and the use of on-board equipment. How to charge the car battery when it is dead?

If the battery is out of charge and the car cannot be started, you can use a charger for charging, or you can choose to charge the battery by jumper.

If the battery loses power, the car should be started soon, and then the generator will charge the battery.

Speaking of car generator charging, it means that when the car battery is insufficient but the car can still be started, the generator can be used for charging while the car is running. A part under the hood connected by multiple belts is the generator of the car. After the car is started, as the engine runs, the generator is driven to generate current. The current flows through the vehicle's voltage-stabilizing transformer, and part of it will be provided to the vehicle When using electrical appliances, the extra part will charge the battery.
