When Should You Replace Your Car Battery?

An essential element of the automobile, the battery is unfortunately not eternal and its lifespan is limited. It must therefore be replaced as soon as necessary under penalty of repetitive breakdowns, in particular linked to starting problems.

Do the batteries have a lifespan?

Yes. Any battery has an average lifespan of 4-5 years depending on its brand and quality. But this lifespan also depends on the use made of it. A highly stressed battery, for example in the case of mainly urban journeys and requiring numerous starts, discharges faster than normal. The fact of making only short journeys does not allow the battery to be recharged correctly, resulting in premature aging. On the other hand, a battery used mainly for long trips can last well beyond its average life, especially if it benefits from good maintenance. Good to know: beware of strong temperature variations

Significant temperature variations significantly affect the life of a battery. Very low temperatures, but also high temperatures, are real enemies for your battery.

What are the signs that your battery is running low?

There are some noticeable signs that your battery is starting to wear down. This is particularly the case when the car is struggling to start in the morning, or if after a few strokes of the starter, the latter can no longer start the engine. If you notice that the battery is discharging too quickly, it’s time to replace it. Recharging can sometimes temporarily remedy the problem, but if the charge does not last long, it is better to charge the battery.

Also, be aware that a battery whose terminals are oxidized or in poor condition has difficulty recharging because part of the current produced by the alternator is lost. To know the state or form of its battery, the use of a voltmeter is judicious. The ideal voltage, the engine stopped, is around 12.5 volts. If necessary, a quick visit to your mechanic will allow you to check the state of charge of your battery without requiring an appointment. Good to know: if your battery is recent, run the warranty

A recent battery that discharges abnormally may have a manufacturing defect. If this is the case, do not hesitate to contact the retailer. Generally, the batteries are guaranteed for two to three years depending on the brand.

Are gasoline engine batteries the same as diesel engine batteries?

No. A diesel engine requires more power to start. The spark plugs must also be preheated to allow the diesel to burn. All this requires a greater electrical input and therefore a more powerful battery. If it is possible to install a diesel battery on a petrol vehicle, the opposite is not possible, at least in the long term. The fact of using a “petrol” battery on a diesel vehicle would quite quickly lead to power problems at start-up as well as premature discharge of the battery.

If your battery is getting old, be aware that its life is limited and it is better to change it before the appearance of problems related to its age. If your vehicle begins to have trouble starting after only a few days of parking, it is because the battery can no longer maintain its optimal charge and is beginning to tire. This is one of the main warning signs of a tired battery.
