how long does a car battery last on average
Under ideal conditions, one automobile battery can last up to six years, but several factors decrease this optimal lifetime. A study of 2,769 sample 12 volt batteries conducted in 2004 showed that the average lead acid battery life is 50 months. Batteries in the northern US had an average life of 56 months compared to those in the south which had an average life of 43 months. Lead acid batteries last longer in cold climates as warm climates increase water loss and sulfation. Car battery life span range is 2 to 5 years.
Letâs assume ideal conditions: no high temperatures, no excessive humidity â in short, a perfect world for your car. Under these conditions, you can probably expect your car battery life to be about six years. On average, a car battery lasts between two and five years. If you live in the northern United States, your car battery lifespan will be longer, because youâre in a cold climate.
