The main function of a car battery is to start your car and is rechargeable. It uses its charge to power the vehicle systems while it’s parked. Once you start the car, the car generates additional electric power to recharge the battery.

Over time, a battery loses its capacity or ability to hold charge. One day, a weak battery will not be able to start your car. When the battery is low on charge, a car will need to be jump started. Regular replacement when the charge level drops can prevent this.

On average, a good quality car battery  can lasts between 5 to 7 years. It can last longer if the vehicle is driven daily and is kept fully charged. When parked over long period batteries deteriorate.

How long is the battery warranty? In most cars, the battery is covered for 1 to 5 years but make sure regarding the warranty on purchase of the battery.
How long does it take to recharge a good battery that is low on charge? If the battery is still good, 20-40 minutes of running the engine or driving is usually enough to recharge it. However, be aware that in some cars with electric power steering, the steering assist might not work properly until the battery is sufficiently charged. That can make driving with a low battery dangerous.
If a good battery has not been used for an extended period of time and is completely drained, it might need longer time to recharge.
