2. Not turning off the air conditioner/heater
Many car owners have this bad habit of not turning off the air conditioner before turning off the engine. Like to have the air conditioner start when the vehicle starts. This seemingly harmless little move can seriously damage the battery. Because when the vehicle starts, the air conditioning system will automatically start and start working. At this time, the instantaneous power load of the vehicle is very high, and long-term use will damage the car battery.
3. Using electricity for a long time after turning off the engine
Continuing to use electricity after turning off the engine includes many situations, such as using electrical appliances in the car for a long time after turning off the engine, and forgetting to turn off the lights, etc. wait.
At this time, the car's generator is not working, and the battery is in a "dry consumption" state without charging. The reduction in its capacity is likely to cause the vehicle to be unable to start, and excessive discharge has harmful effects on the battery itself. A lot of damage.
4. Frequent starts
For novices, stalling is common. The editor recommends that each time you start the engine, it should not exceed 3 seconds. If the first startup fails, don't rush to restart it again at this time. Continuously starting the motor will definitely cause excessive discharge of the battery and damage it. Therefore, the time interval between restarts should exceed 5 seconds.
5. Listening to speakers for a long time
Some music enthusiasts are obsessed with music and often modify the sound system in their cars and install high-power speakers. Whether it is driving or idling waiting for someone, the stereo must not be stopped. But everyone should be careful.

6. Do not unplug external devices after turning off the engine
In order to improve the convenience and comfort of using the car, many car owners often use this power interface to connect many external devices, such as GPS and driving records. instruments, air purifiers, etc. These devices rely on power from the cigarette lighter to work.
The additional electrical equipment itself increases the burden on the battery, and the cigarette lighter of some models is still in the power-on mode when the flame is turned off. If the external device is not unplugged, the battery power will be consumed and the battery will be lost. battery.
Insufficient battery voltage: When the battery voltage is insufficient, the horn and lights can be on, but the ignition will not start. The battery light will be on as long as the key is in the ON position before the ignition is started. The car battery voltage is low; specific detection method: Use a three-purpose meter to test the battery voltage. If it is below 10V, choose to replace it. If it is around 11V, use it reluctantly, but be prepared for replacement. Can be used above 12V.
Confirm the quality of the gasoline added and check whether it is due to carbon depositsCause: If the vehicle is driven for about 20,000 km, focus on checking and cleaning the throttle; checking the ignition switch; testing and inspecting the starter, gasoline pump, sensors and other related components of the starting and fuel supply system. In addition, after powering on, do not start it immediately. Wait for thirty seconds to one minute before igniting it to see if there is any effect.
The lights in the car were not turned off.
The car was not locked and was still on standby. The details are as follows:
If the battery indicator light is on, it means that it is in a discharge state. If it goes off after starting the machine, it means that the generator is charging the battery and it is in a charging state. This is the case.
