When Does a Car Battery Need to be Replaced?

The primary function of the battery in your car is to assist in the ignition of the engine. Modern cars come with a maintenance-free 12V acid battery, that is rechargeable. The battery charge is used for powering the electricals when your car is parked, and to turn on the engine anytime you want to start it. Once the car is started, the alternator in your car generates electric power to recharge the battery. But over time, the battery loses its capacity to hold charge. And one day, you won’t be able to start your car. By then, you will be wondering where to service my car in Dubai. Your car battery should be replaced to avoid this situation. On average, a car battery has a life of 5 to 7 years. The battery of a vehicle that is driven daily and kept at full charge lasts longer than other cars. Parking for long periods of time can badly affect the life of your battery. Many car owners have said that their battery lasted for a good 10 years, and this can happen if you take good care.
