7 reasons why car batteries quickly run out of power and break down

(Baonghean.vn) - For every car, the battery is an important part. However, there are habits of the car owner as well as external factors that are unintentionally damaging this part.

1. Too cold or too hot

Operating in extremely hot or cold conditions can affect the internal structures of the battery - especially the chemical components - which can lead to damage or poor output.

During daily use and maintenance of the vehicle, you should limit long exposure to the sun, avoid situations where the vehicle is running fast on the street and then immediately stores the vehicle in a narrow garage, not allowing the heat generated from the engine to dissipate.

This phenomenon will cause lead sulfate crystals to accumulate, reducing battery life while charging time will be longer, and the battery may be damaged quickly.

2. The engine has not been started for a long time.

For newer cars with original and normal electrical systems, turning off the engine does not mean that the car no longer consumes electricity. When the car is not running, the control command receiver and anti-theft system are still ready to operate. Therefore, when left for a long time, the amount of electricity in the battery will be below the threshold to start the car.

3. Continuous driving in short distances

Many people travel only a few kilometers by car each day, but can start the engine dozens of times.

This is a “disease” of most cars operating in the city. Constantly starting the engine just to move a short distance will quickly reduce the battery capacity.

For cars that only make short trips around town, the charger will not have enough time to fully charge the battery. To put it in perspective, this is similar to constantly charging your phone or laptop, causing the battery to quickly "wear out".

According to technicians, on average once a month, you should take your car out on the highway and drive continuously for about 10 - 20 minutes at a stable speed so that the battery is charged as optimally as possible.

4. Using too much electricity in the car

Turning on lights and devices in the car when the engine is not running, such as headlights, turn signals, interior lights, air conditioning, and entertainment audio systems, will cause the battery to lose power quickly. Especially when the battery is completely discharged, then using a jumper to recharge the battery will cause your battery to deteriorate faster. In addition, forgetting to turn off electrical devices when leaving the car overnight will also cause your battery to drain quickly.

5. Too many devices loaded

Adding too many accessories to your car without considering upgrading and ensuring the safety of the electrical source can be dangerous.

In every car, every electronic device will use a small amount of energy to maintain operation - even when the car is turned off (like the clock, the locking system, the alarm system ...). Although with factory cars, this is not a big problem because the manufacturers have their own safety calculations. However, there are still two cases that can lead to risks.

First of all, there are risks in the electrical circuit (short circuit, damaged components, etc.) that can cause the load to increase, causing the battery to run out of power in a short time or reduce its lifespan.

Second, many car users today tend to "upgrade" electronic devices, lighting... This group of devices, if not calculated and installed properly, will be a threat not only to the battery but also to the vehicle's electrical system.

6. When the car is flooded

If your car is unfortunately flooded, trying to restart the car will cause water to flow into the wires, plugs, etc., causing damage to the power source. This is one of the reasons why the power source is quickly exhausted and many parts of the car are damaged.

If a flooded vehicle is not checked and serviced promptly, the battery will be more susceptible to damage. Water can corrode the terminals and cause the battery to no longer function as well as before.

7. Not having regular maintenance

If you do not do regular maintenance, you will not be able to know how much fluid is left in the tank, whether the surface and terminals of the tank are still white and clean. That will make the operation of the car battery less efficient, significantly reducing its lifespan.

Therefore, you need to regularly check the battery, clean the surface of the battery, and use battery testing equipment to avoid unnecessary problems.
