You should already know that forgetting headlights and lights on or leaving the sound on with the car turned off are factors that contribute to a shorter battery life. Actually, these are the main causes that increase the wear of the part and, consequently, decrease its longevity.

Vehicle stopped for a long time

It may not seem like it, but leaving the vehicle stationary for several days without starting the engine once is another factor that reduces car batteries’ life.

It is recommended to start and stay for a few minutes with the car running. If you use it a little, try turning it on at least once a week.

We live in a tropical country. During the high temperatures, while others, in certain periods, the climate gets to be negative. And batteries tend to wear more when both extremes occur: too cold or too hot.

In the cold, the battery’s tendency to draw more energy to maintain its full functionality. When the temperatures are high, the tendency is for the lead alloys to corrode more quickly and the component to have a shorter service life.

Daily attention

As we showed earlier, they are small slips, like forgetting on headlights, which shorten the life of the batteries. Therefore, always being attentive before locking the car is the main recommendation to increase durability.

Forget refurbished batteries

Refurbished batteries are those collected when they are already at the end of their life and modified to get back to work. For this, an electrolyte exchange is made. In other cases, the batteries are opened, and the plates disassembled to be placed in another piece, with a new electrolyte.

Because they are sold at prices well below the conventional, initially, reconditioned batteries seem like a good option. However, after a short time of use, the driver will notice that it was not worth it and will need to change the part again.

Do the correct maintenance

Experts recommend reviewing the car every 10,000 kilometers traveled. When taking the vehicle to the specialist to check oil, rotate the tires, and make other adjustments, it will also monitor the automotive battery’s life. If necessary, you can clean the terminals of the part or suggest a replacement.

Top car battery brands

Each of them has different lines and guarantees. It is worth evaluating case by case which is the best option for your vehicle. If you need help, look for a specialist in the subject to guide you in your choice.

How to properly dispose of the battery

When your car’s battery life runs out, it’s time to change it. But do you know how to dispose of the current component? Because it is produced with various chemical components, placing the automotive battery in any garbage is extremely harmful to the environment.

If you have experience and change the part yourself, find a suitable disposal to dispose of the battery. If you don’t know, take it to a specialized location and let the professional replace and dispose of the component.
