As drivers know, a car battery typically lasts 2 to 3 years. However, improper selection or neglect of maintenance can cause the battery to run out of power prematurely, shortening its lifespan. In our daily driving, these actions often shorten the battery's lifespan.
1. The cigarette lighter is in power-on mode when the cigarette is off.
The cigarette lighter is a component found in all cars, providing a convenient source of light for drivers to smoke. It relies on electricity to light cigarettes and is a crucial power output interface in the vehicle. Many car owners, for added convenience and comfort, often connect various external devices to this interface, such as GPS devices, dashcams, and air purifiers. These devices all depend on the cigarette lighter for power. These additional electrical devices increase the burden on the battery, and in some models, the cigarette lighter remains powered even when the engine is off. If external devices are not disconnected, this will drain the battery and cause damage.
Generally, maintenance-free lead-acid batteries are used, with a typical lifespan of around 3 years. However, if used properly, the lifespan of a battery can be extended to 5 to 6 years. Of course, if used improperly, the battery may fail in less than 3 years. This significant difference is largely related to the daily driving habits of car owners.
2. Do not turn off the multimedia or air conditioning system before turning off the engine.
Some car owners either forget or want to save time by not turning off the multimedia or air conditioning systems before turning off the engine. When the car is started again, these systems will automatically turn on, which will cause the vehicle to be under excessive power load. In particular, if the air conditioning is left on, it will cause excessive wear and tear on the battery in the long run.
3. Prolonged use of electricity after the engine is turned off.
Continuing to use electricity after the engine is off includes many situations, such as using in-car electrical appliances for an extended period after the engine is off, or forgetting to turn off the headlights. In this situation, the car's alternator is not working, and the battery is in a "dry discharge" state without being charged. Its reduced capacity may prevent the vehicle from starting, and excessive discharge can cause significant damage to the battery itself.
4. Prolonged or frequent ignition
Each time you start the engine, the ignition time should not exceed 3 seconds. If the engine fails to start on the first attempt, do not try to start it repeatedly. Wait 15 seconds before trying again. Otherwise, the battery will frequently supply a strong current to the starter motor, causing damage to the starter motor itself.
5. Do not disconnect external devices after turning off the engine.
With the increasing number of external devices in cars, the burden on the battery is increased by these additional electrical devices. Furthermore, some car models have cigarette lighters that remain powered even when the engine is off, which degrades the battery.
