Why Does My Car Battery Keep Dying? Causes and Solutions

Anh Tuan, owner of a 2018 Hyundai HD700 truck, walked into a truck repair shop on Nguyen Van Linh Street, Long Bien District, with a worried look on his face. He complained to Thang, the technician: “My truck battery keeps dying. Every morning, it won’t start. Do you think I need a new one?”. Thang smiled and said: “We can replace it right away, but we need to find out why it’s happening. Do you drive a lot? Do you regularly check your battery?”. Anh Tuan hesitated: “I drive all the time, delivering goods all over the city, sometimes even to Soc Son. As for checking the battery… I only remember to do it occasionally.”

Anh Tuan’s story is not uncommon. Many truck owners, especially those operating in Hanoi, often experience frequent battery drain. So, what are the causes and how to fix them?

Causes of Car Battery Drain

1. The Battery Needs Replacement

Like any other part of a vehicle, a car battery has a limited lifespan. The average lifespan of a car battery is 2-4 years, depending on usage and maintenance. If the battery is too old, its performance will decline, leading to difficulty starting the vehicle or even a dead battery.

2. Improper Vehicle Usage

Driving habits also significantly affect battery life. Some habits that can shorten battery life include:

• Using multiple electrical devices when the engine is off: Using headlights, air conditioning, the sound system… when the engine is not running will quickly drain the battery.
• Driving short distances and frequently turning off the engine: When driving short distances, the battery does not have enough time to fully recharge. Frequently turning off the engine for short periods also makes the battery work harder.

3. Electrical System Faults

• Malfunctioning alternator: The alternator is responsible for charging the battery when the vehicle is running. If the alternator has problems, the battery will not be fully charged, leading to a dead battery.
• Short circuits: Short circuits can occur anywhere in the vehicle’s electrical system, causing the battery to continuously discharge, leading to a dead battery.
