How long can a car battery last?

While many components are essential to the operation of a vehicle, nothing will work without a functioning battery. However, these wonderfully compact energy sources do not last forever. Over time, their ability to hold a charge weakens and they eventually ‘die’. After the battery has expired, car owners should know how to detect when the car needs a new battery.

When buying a new battery, it’s helpful to a car owner’s routine maintenance schedule to know how long the car’s battery will last. Of course, no one wants to have to buy a replacement product too often.

However, there is always the possibility of something going wrong and the driver may need to replace it before it reaches the end of its life. Batteries are not something that one can repair. Normally, the average life of a car battery is usually between 3 and 5 years. Of course, this time can be extended by taking good care of the car. This timeline is only applicable to conventional batteries for cars with internal combustion engines.

With electric cars like the Tesla Model S becoming more and more popular, lithium-ion battery technology is evolving rapidly, and these battery packs can last a lot longer than in conventional gasoline cars. . In addition to being designed differently, they are also based on a different type of charging system.

Most electric vehicle manufacturers will offer warranties of five to eight years, but the best electric vehicle batteries should last around 10 to 20 years. However, these batteries are not like the traditional batteries found in conventional cars.

There are several warning signs that the battery may be damaged before its shelf life is reached.

The battery is “dead”: The most obvious sign is that the battery does not start the car at all. In this case, the car owner should buy a new battery pack.

Car is hard to start: If the car battery is not completely dead, it may have difficulty starting. This is sometimes attributed to cold weather, but it can also be a sign of a failing battery. The reason is that it is old and does not generate enough power for the starter.

The warning light on the dashboard comes on: There are warning lights on the dashboard and a malfunctioning battery can trigger the check engine light or the car battery indicator light. Whenever these lights come on, the driver should take the vehicle in for inspection and repair.

There is corrosion: If the vehicle owner sees white substance around the metal parts of the battery, it may be corroded. This can affect the voltage of the car battery and can make it harder to start the car.

The battery case is dented: Continuous exposure and variation between hot and cold temperatures can cause the battery case to swell or crack. This could cause the chemicals inside to leak or not react properly, potentially causing problems.

The car has an electrical problem: The car battery is responsible for operating all the electronic devices in the car, so if it is not working properly, these equipment will be affected. These can include dimmed or flickering lights in the cabin, or even problems with the power door locks and car windows.

Low voltage: Most of the above situations are the result of low voltage. If the car owner wants to make sure the battery is in good working order, all it needs to do is check it in person. Users can use a voltage tester and connect the cable to the positive and negative terminals of the battery. If the scanner shows that the voltage is less than 11.8V, then there is a good chance that the battery has a problem.

How to keep the car battery working for a long time?

There are many ways to prolong the life of the battery, such as:

Using trickle chargers can keep the battery from draining during periods of inactivity without overcharging it.

Avoid repeated stops and starts – repeated ignition sequences without sufficient time to charge between cycles can damage the vehicle’s battery.

Take long trips – many short trips will shorten the life of the battery, while one long trip will keep it fully charged.

Unplug the unnecessary – extra accessories like the dashboard can be a huge drain on the battery if the driver doesn’t get a chance to charge the battery properly. Likewise, leaving a car with a radio or audio system playing for hours without starting or driving will also drain the battery.

Use the correct type of battery (battery) for your car: Using a battery that does not meet your vehicle’s specifications can cause problems.

Nothing lasts forever and batteries will eventually need to be replaced. Riders can use the tips provided to try to prolong its life, and hopefully a guide to the warning signs will ensure they know when to get themselves a new set of batteries.
