Why does the new battery run out of electricity and recharge it?Does the new battery need to be charged for 12 hours?

Whether a new battery needs to be used up and then recharged is determined by the type of battery. The new battery is used up and recharged refers to the nickel-cadmium battery. If it is not fully charged and discharged for a long time, it is easy to leave traces in the battery, which reduces the battery capacity and makes it impossible to perform large-scale charging and discharging. The phenomenon is the battery memory effect.

However, the current car batteries use lead-acid batteries and maintenance-free batteries, and there is no need to charge them when they are used up. Therefore, the new battery does not need to be charged for 12 hours. If the battery is completely empty, you need to use a dedicated charger for charging to ensure that the engine can be started.

In addition to being charged by an external dedicated charger, car batteries are also being charged during normal driving. When the engine is started, the rotation of the engine drives the generator to work. At this time, the generator charges the battery. In addition, the generator also supplies power to other electrical equipment to maintain the normal operation of the car.

Under normal circumstances, the battery life cycle is 3-5 years, and as the number of charge and discharge continues to increase, the performance of the battery will change. If the battery voltage and internal resistance do not reach the limited value, it needs to be replaced. .

For gasoline vehicles, the battery plays an important role to ensure the normal start of the engine. At the same time, when the engine is not started, the battery power can be used to power other electrical equipment, such as car lights, air conditioners, etc. However, car owners must also learn to prepare for the lifestyle habits of using the car, which can better extend the battery life cycle. For example, before starting the engine, do not use high-power equipment such as headlights and air conditioners for a long time.
