One of those key components that Im sure you have heard of is your car battery. A car battery is the most underrated and the most important piece of equipment your car needs to drive, without it you could never ever start your vehicle. The primary function of your cars battery is to start the engine by powering the starter motor to provide electric power to the spark plugs in order to ignite your vehicle s fuel. Your car battery also provides power for other components such as its lights, horn and climate control system. When a battery gets old (3-4 years) it can eventually start to wear out and need replacement but, if youve got a new battery under your hood and your battery keeps dying, there may be something else causing it to die so quickly. Why does my car battery keep dying? Keep reading to find out. Read More: Too Many Short Drives. If you are always taking short drives, this may be causing your battery life to end too soon. The most taxing use of your cars battery is to supply power to your vehicle s ignition.


If you keep on starting and stopping your vehicle before your alternator has time to recharge, this would account for the reason why your car battery keeps dying and isnt lasting as long as it should. Faulty Charging System. In order for your car battery to recharge, your vehicle s alternator must provide it with energy. If there is something wrong with the system, your car battery could be dying too soon. Extreme Hot and Cold Temperatures. Temperatures that get get above 100 degrees or below 10 degrees Fahrenheit can be very tough on your car battery. A build-up of lead sulfate crystals can occur when leaving your vehicle in these temperatures for too long. The sulfate buildup can shorten the life of your battery and increase the amount of time it needs to be recharged.

Sharing is caring! A battery is definitely not the sexiest item on a car. In fact, its safe to say that very few people ever inquire about these little black boxes when researching their next vehicle purchase. However, a car with the best gas mileage, the fanciest safety features, and the most exotic hood ornament wont even make it off the lot if the battery doesnt workwhich arguably makes it the most important aspect of the car.


A car battery works exactly the same as any other battery, says Richard Reina, product trainer at CARiD. com. The battery has a positive terminal and a negative terminal, and electrons flow through wires from one terminal to the other. The primary function of a car battery is to start the engine by powering the starter motor and provide electric power to the spark plugs to ignite the fuel. It also provides electric power to the lights, horn, heater, etc. Thats an awful lot of responsibility for a 12-volt batterythe voltage used on most modern vehicles, especially considering that the batteries in your household flashlight supply a whopping 1. 5 volts of electricity. And just like your typical flashlight, camera, and smoke detector batteries, car batteries eventually wear out and need to be changed from time to time. An average battery [life] will be in the 3-4 year range, says Bob Augustine, technical training manager for Christian Brothers Automotive. But that life can be dramatically shortened depending on how you treat your car: Extreme Temperatures : Extreme cold and/or heat stress the internal chemistry of the battery and induce premature failure, continues Augustine.


And the definition of extreme might not be as far-reaching as you think. The temperature need only creep above 100F or run below 10F to result in very bad news for your car. It turns out that car batteries eventually experience battery sulfation, a build-up of lead sulfate crystals. And leaving your car in extreme conditions will speed up the process. This sulfation can shorten the life of the battery and lengthen the amount of time needed to charge the battery, says Augustine. Faulty Charging System : Its the responsibility of the alternator/generator to keep the battery charged. But if it provides a charge thats too high or too low, then you have a problem. The battery is 12. 6V DC when fully charged, so the alternator/generator creates a voltage between 13. 4V-14. 7V DC to maintain a correct state of charge based on the electrical load, says Augustine. If the battery is being under or over charged the culprit could be anything from mechanical flaws a loose connection, a bad circuit, a faulty alternator to driver error, such as forgetting to turn off the lights. Short-Term Driving: Driving your car too often can contribute to a short battery life, but the number of miles driven isnt nearly as important as how they were accumulated in the first place.


Many short drives will lessen the life of a battery faster than a few long trips, says Reina. This is because the most taxing use of the battery in your vehicle is the initial engine start. And keep in mind that while the ignition is requiring this extra burst of power from the battery, the alternator hasnt even started the recharging process, which is time consuming and usually occurs while you drive. Keeping up with your cars regular maintenance schedule is the best way to prevent having to shell out too much cash for car batteries. Losing a battery once a year for three years indicates something off in the electrical system; it could be as simple as a glovebox light that stays on even when the doors closed.
