1. Extreme weather

Hot weather: In high temperature, the temperature on the surface of the car battery will be very high, which will accelerate the evaporation of the liquid inside the battery and damage the battery. And it will also accelerate the chemical reaction inside the battery, resulting in increased pressure inside the battery, shortening the service life of the battery.

Cold weather: when the temperature is too low, it will make the fluidity of the electrolyte inside the battery deteriorate or even freeze, which will lead to a decrease in the rate of chemical reaction and a decrease in discharge efficiency. In addition, on the basis of the optimal temperature, the temperature drops 1 ℃ battery capacity by about 1%, when the temperature reaches minus 10 ℃, the battery capacity will drop by about 32%. And low temperature will also make the battery internal resistance increase, reduce the battery discharge efficiency, is not conducive to the long-term use of the battery.

2. Parasitic current

After the car’s power supply, all electrical appliances and other switches are turned off, some circuits may still continue to consume battery current, these consumption is unavoidable, and may deplete the battery power in the long run.

3. Old Battery

The general life of the battery in 3 ~ 5 years, with the increase in the use of time, the performance of the battery is also reduced. If your battery has been in use for too long, it may be drained soon after being fully charged, at which point you need to consider replacing it with a new one.

4. Alternator failure

A car’s engine relies on the battery when starting, but when the car is running, it needs the alternator to power some electrical devices and charge the battery at the same time. If the alternator malfunctions, the battery will not be charged properly, which will likely result in your car not starting or stalling frequently, and it will also cause damage to the battery.

5. Electrical components not turned off

When the engine is turned off, if you forget to turn off the interior lights, windows, doors, and other devices, it may cause them to continue to draw battery current to the point of draining the battery. And if some electronic devices inside the car malfunction it may also continue to drain the battery. Therefore, when we get out of the car, we should check the vehicle carefully and turn it off completely to prevent damage to the battery.

6. Charging Problems

When charging the battery, use the correct charger and also connect the negative terminal of the battery to the negative terminal of the charger, if you use the wrong charger, it may reduce the charging efficiency or damage the battery. If the wrong charger is used, it may reduce the charging efficiency or damage the battery. Moreover, when the battery is charged at a lower temperature, the charging time is longer, and it is easier to drain the battery, and it needs to be recharged more often, which will shorten the service life of the battery.

7. Short distance driving

When you drive short distances frequently, the alternator charge for the battery may not be able to supply the next start of the car engine. Therefore, when the car is started again, the power required by the engine may drain the battery, causing great damage to the battery.

8. Loose battery terminals

Battery terminals are components used to connect the battery to an external conductor. If the positive and negative battery terminals are loose, not only will the battery not be charged properly, but it will also prevent the battery from providing power for the car to start, thus preventing the car from starting. If not found and repaired in time, it is likely to damage some of the vehicle’s electronic equipment.

9. Parking the car for a long time

When you don’t use your car for a long time, if you don’t charge the battery in time, it is likely to drain the battery. This is because some electronic devices may also continue to draw power when the car is turned off.

10. Body leakage

If the vehicle malfunctions and the body leaks, it will continue to drain the battery, which can easily deplete the battery and reduce its performance as well as shorten its service life.
