● Age of the Battery – Automotive power cells are products that won’t last forever. Proper maintenance and upkeep will only enable you to maximize the life expectancy of a car battery. Once it reaches its peak or its entire lifespan, the battery will eventually die, and the only option that you have is to replace it with a new one. A typical car battery lasts four to six years and if it starts to show the signs of failing, think about how long the battery has been. Maybe its too old and it already reached its maximum lifespan.
● Short Drives – Starting the vehicle’s engine is the heaviest task a car battery handles. Driving in short distances or quick travels forces your battery to work harder since it will attempt to start your engine several times. Having a driving routine like this will shorten the life of a car battery. Driving habits like this will make it difficult for your battery to be fully charged which will eventually lead to battery failure. Keep in mind that avoiding short drives will allow you to extend battery life.
● Irresponsible Usage – Overusing a car battery or leaving some of the car’s electronic components ON when the engine is not running will quickly drain the power cell. Using the vehicle’s air conditioning unit, radio and lights with the engine OFF will force the battery to provide the power for electronics. This will prevent the battery to recharged and drain its energy at a higher rate. A frequently discharged battery has a shorter life because it results in thinner and weaker battery panels that may trigger sulfation which will quicken the phase of deterioration.
● Poor Maintenance – A poorly-maintained automotive battery has a shorter battery life compared to a well-maintained battery. This doesn’t need a lot of explanation but taking well good care of a car battery will boost its lifespan. Enabling it to serve you for several years, helping you to reduce maintenance cost and save money.
