汽車電池全攻略：功能、耗電原因與保養建議

📢 What is the function of a car battery?

Besides starting the engine, a car battery powers many electrical components, such as headlights, brake lights, and other lighting, air conditioning, the car’s navigation system, power windows, and windshield wipers.

📢 What is a dead battery?

A dead battery means the battery’s power is too weak to start the engine—in other words, it is "out of charge."

📢 What causes a battery to run out of power?

Battery depletion occurs due to discharge and deterioration.

Leaving the lights on can drain the battery, but even if the lights are off, the battery will discharge if the car is not driven for a long time. Additionally, batteries are consumable items with a limited lifespan. As their performance declines, they eventually lose power.

📢 How can you prevent battery depletion?

Make sure to drive your car regularly to keep the battery sufficiently charged.

Also, check the battery’s condition periodically.

📢 What is an Idle Stop & Start (ISS) compatible battery?

Idle Stop & Start is a system that automatically turns off the engine at red lights or during traffic congestion to improve fuel efficiency and reduce environmental impact.

Frequent engine start-stop cycles place a significant burden on the battery.

Therefore, vehicles equipped with an Idle Stop & Start system require a specialized battery with strong recovery capabilities and durability.

📢 What is a charging control vehicle battery?

Charging control vehicles regulate battery charging when the battery is sufficiently charged to reduce engine load and improve fuel efficiency.

Frequent charging and stopping put heavy stress on the battery.

Therefore, these vehicles require a battery with high charge acceptance that is compatible with charging control systems.

📢 How often should you replace your car battery?

We recommend replacing your car battery every two to three years after installation.

Battery depletion due to discharge and deterioration is significantly affected by driving habits, temperature changes, and other factors.

Additionally, vehicles with charging control systems or an Idle Stop & Start function place greater stress on the battery, shortening its lifespan.

To prevent sudden battery failure, we recommend regular inspections and preventive replacements.
