There are several reasons why a car battery may fail prematurely. Some of the most common reasons include:
Overcharging a car battery can cause damage to the internal structure of the battery and lead to a reduction in its lifespan. If you got a faulty alternator, your chances for battery failure are high. Check your car battery voltage after a long ride, switch off the engine, Leave the car for an hour and check the voltage using a multimeter. If the voltage is above 14v, it is a symptom that your car battery is over-charged.
Exposure to extreme temperatures, either hot or cold, can cause a car battery to fail prematurely. High temperatures can cause the battery to overheat, while low temperatures can cause the battery to freeze and become damaged.
Lack of maintenance:
A car battery requires regular maintenance to ensure that it is functioning properly. Neglecting to maintain the battery can cause it to fail prematurely.
- Vibration: Vibration can cause damage to the internal structure of a car battery and lead to a reduction in its lifespan.
- Electrical drains: Electrical loads like headlights, audio systems, GPS, and other devices can drain the battery power.
- Old age: A car battery has a limited lifespan, and it will eventually need to be replaced regardless of how well it is maintained.
It is important to note that, preventing the above causes and regular inspection and maintenance of car batteries can prolong the life of a car battery.
