No battery can last forever. However, proper maintenance can give it an extended life.
Every car has its battery placed under the hood and is easy to spot. Most car batteries are large with either rectangular or square shaped boxes connected with two cables. These cables should be kept clean and corrosion free. If you spot small crystals or white powder on them, clean them up immediately with a wire brush.

When handling a battery, be very careful and use proper covering and clothing, gloves and goggles. A torch light should be used instead of a match when working near the battery.
Switch of all possible electrical appliances. Your car battery is likely to produce gases which are highly explosive.
The way you start and stop the car engine or the climatic changes also play an important factor to determine the life span of the car battery.
When your car engine has a starting problem, you may need jump starting. Attach jumper cables to a working battery and then to your car’s battery.
The positive cable should be attached to the positive terminal of the “dead” battery and then to your car’s battery.
The negative cable should be attached to the negative terminal of the working car battery and the other end to metallic part of your car engine. Now you can start your car engine with the help of the working battery. Let the engine idle for a whole before switching on the headlights.
Once you have done all this, you can start your car with the help of your dead battery and remove all cables in reverse order.
Make sure the clamps do not touch each other when removing them.
