What Causes a Car Battery to Die Quickly?

Batteries are components that have a lifetime. When the lifetime runs out, the battery will die and be useless.

How long is the car battery lifetime?

It's not certain. Some batteries have a long life, and some get damaged quickly. In fact, driver habits can also affect battery life.

So what are the things that make a car battery die quickly?

Died Battery Meaning

Died battery has two meanings, first is a battery that dies due to loss of voltage, and second is a dead battery because electrolytes are not able to store electrical energy.

For the first, it can be overcome by battery recharging. The battery only loses power, because the function of the battery is to store electrical energy, so when all the energy in the battery is used up, the battery will lose voltage.

But for the second, the battery must be replaced. Because the battery capacity to store electrical energy is very low. So that the battery will be fully charged quickly, but the maximum energy stored in the battery is small.

In this article we will focus on the second mean, it is a battery die because it has broke electrolytes. For battery loss of voltage, that's a rare occurrence. Because every vehicle has a charging system.

so the battery will always be fully charged during engine run.

Here are some things that make car batteries die quickly.

1. Additional accessories that require electricity

For car owners, feel happy when their car is different from the others. One way, by adding some accessories.

Examples of accessories installed on a car are variation lamps, HID projector headlights, interior speakers, etc.

The accessories mentioned above require a supply of electrical energy. It comes from the battery.

So when the car's electrical load increases, the discharge rate on the battery will also increase. The engine has a charging system, under normal conditions the charging system is able to supply electricity to the vehicle and the battery still has residual energy to recharge the battery.

But if the vehicle's electricity load is higher, the battery recharge will be very low. So that the battery is not in a full charge condition even though the engine is running for a long time.

This will trigger the battery storage capacity to decrease, so the battery dies faster.

2. Engine often to On / Off position

when you drive, it's not always smooth. The car will stop due to traffic light, or some reason.

If you always turn off the engine when the vehicle is stopped, it makes the starer system work more often. So that it need more electric that stored in the battery.

This makes the recharging process of the battery does not make the battery at fully charged. Because the results of the recharge will discharge directly when the next starting process.

So, don't make it a habit to turn off the engine when you are in a driving position. Turn off the engine when you have reached your destination, and the vehicle has not been used for a long time.

It keeps the battery fully charged. So that the battery capacity remains normal.

3. Battery exposed to heat

Heat makes the hydrogen ions in the battery evaporate faster. Hydrogen is one of the ions in battery electrolytes. When the engine is running, the battery recharges. When the process is recharged, the hydrogen will be released from the original molecule.

If the surrounding conditions are hot, this can force the hydrogen to evaporate into loose air. If the hydrogen concentration in the electrolyte decreases, the capacity of the battery to store electricity is reduced.

That is why the battery has a heat sink. This will prevent overheating from getting into the battery.
