How often do you need to replace your car battery?

“Signs” that show you it’s time you did it.

Actually, this is the question that both experienced drivers and beginners want to get the answer to. In this article, we’ll try to answer this question. We’ll provide you not only with the experts’ recommendations, but we’ll also tell you of the certain signs that show a car owner that it’s time he/she replaced the car battery with a new one.

If you simply don’t want to be familiar with all the peculiarities of a car battery elements, the principles of its functioning and how to check whether a car battery is working properly, you may follow a simple rule. Here it is: “You need to replace your car battery every 4 years”.

Many car owners may disagree with this recommendation. The thing here is that manufacturers claim that car batteries can successfully work for 6 or even 7 years. They are not lying. The crux of the matter is that the working capacity of a car battery depends not only on the quality of the battery itself, but also on how you use it. If you regularly charge your car battery during these 4 years so that it’s charged completely and don’t use your car when the temperature is too cold, if you use an original charger to charge your car battery and make sure that there aren’t too much devices in your car that require a source of energy “to feed” on, it’s very likely that your car battery will continue to successfully function for a lot of years. However, everything gets a bit different when it comes to using your car battery in real life. We often face the situations when the temperature changes rapidly and we have to make quick trips to somewhere. Besides, the number of the electrical devices in our car is constantly increasing. We have MP3-players, GPS and other devices that we need in our car. All the above mentioned factors decrease the service life of your car battery significantly.

If you don’t want to replace your car battery every 4 years (and you, actually, want to prolong its service life) we recommend you to pay attention to certain “signs” that you may start receiving from your car battery after some time.

There first “sign” on the basis of which it should become obvious to you that you need to have your car battery replaced is the following: the level of your car battery charge is not enough to charge your car. Don’t throw the battery right away if you face such a situation. Charge it completely and see whether you manage to start the engine of your car with your battery being completely charged. Continue driving with this car battery for several weeks and keep an eye on its level of charge. If 2 weeks later you see that your car battery’s level of charge again is not enough to start the engine, you can dispose of such a battery. It doesn’t keep its charge.

The 2nd signal you may get if the service life of your car battery comes to an end is the decrease of voltage in the electrical system of your car. If there occurs a failure concerning the work of your car’s electrical system, you need to necessarily test your car battery in order to see whether it needs to be replaced.

If you use your car battery for more than 4 years already, you may start receiving other signs from it that prove the fact that you need to start thinking of buying a new car battery. While making short trips around your city, pay attention to whether your car battery keeps its charge or it needs to be regularly charged. If your car battery doesn’t keep its charge for at least 2-3 months, you need to replace it.

The 3rd common sign that you may get is corrosion on your car battery terminals or spots on the battery itself. If you see any of these, take it seriously. These spots and corrosion may be the result of the electrolyte leaking out of your battery.

  1. I like how you mentioned the things that need to be done in order to get the battery working for a long time. What I like the most is the part where you talked about charging it regularly and not using the car if the temperature is too cold, because I usually do that. But I had my charger replaced, so is that a bad thing? I don’t think my batteries need replacement, but I’ll get a spare one just in case. Thanks for the informative article.

  2. With winter coming up, I want to make sure I take care of all the maintenance my car needs so that it is running properly and can keep me safe. It’s interesting how you point out that many manufacturers claim that you can have the same car battery for 6 or 7 years, but in reality, it needs to be changed every 4 years. I honestly can’t remember the last time mine was changed, so I’ll be sure to look up my car history and see what I can find.
