How Long Does A Brand New Car Battery Last?

It’s a common question and one that doesn’t have a straightforward answer. This is due to the fact that a variety of elements, including the battery’s kind and driving style, can impact a car battery’s longevity.

A vehicle battery should typically last three to five years. However, if you don’t take good care of your battery, it may only last a couple of years. Your battery might not last as long if you live in a hot region as it would in a colder one.

You may do a few things to increase the lifespan of your automobile battery. To begin with, remember to maintain your battery clean. Your battery’s lifespan may be shortened by corrosion caused by a filthy battery. Second, don’t let your battery discharge too low. A deep discharge can damage your battery and shorten its lifespan. Finally, don’t overcharge your battery. Overcharging can also damage your battery.

Another aspect of regular maintenance is the replacement of your electric vehicle’s battery. Therefore, the battery in your automobile should be replaced every three to four years on average. Again, checking and inspecting Lithium-ion batteries for service visits is a good practice.

However, battery lifespan also depends on the elements of the battery. Such as AGM and Lead Acid batteries are not the same. The AGM battery is more durable and can withstand extreme weather conditions and higher temperatures. They will also last longer and provide more power than lead-acid batteries.
