Let us guess what would have happened. It was a usual day rush hour and you couldn’t catch a breath as you were late for work. You rush to your car wishing every traffic light you hit on the way to be green and then you might reach your office just in time. But this whole plan goes down the moment you start the ignition but your car denies to start. Nightmarish, eh? Now, apart from all the crying and cursing, you wonder why your car battery is draining? Well, if that’s the case, first of all, we’re sorry that you had such a rough day and second of all, if you had taken Pitstop’s battery health check-up service then this would never have happened.

Anyway, what’s done cannot be changed but it sure can be avoided in the future. And for that, first, you need to know how this whole battery system works. The battery sends power from the starter motor to the spark plugs which ignites your car’s fuel while also giving power to other systems of the car such as lights, air conditioning, automatic windows, etc. Every electrical which is present inside your car is directly dependent on the battery. Even the engine won’t start if the battery is not in proper working condition. Hence, from the above explanation, it is wise to say that the battery is the powerhouse of the car and must be maintained at all times without fail.

Now that you know the working mechanism of the battery. It’s time to find out what exactly happens inside your car that drains the life out of it. We’ve curated a list of the top 5 reasons why your car battery could be draining. Read on!

You forgot to turn off the lights

At the end of a long tiring day, a lot of things can slip out of our minds. One of the things could be as simple as switching off the cabin or the headlights of the car. This is one of the most common reasons for a drained battery. When you accidentally leave the lights on, it drains all the power from your battery leaving it dead and as a result, you end up not being able to start your car the next day. Although new cars now come with an alarm feature which warns you the moment you leave the headlights of your car on. But if in case your car does not have such a feature, make sure you check whether or not you’ve switched off all the electricals before you shut your door and walk away from your car.

Faulty charging system

The alternator is the basic component of the charging system. In many cars, a lot of electricals are powered by the alternator. If by any chance the alternator has any loose belts or worn-out tensioners, it will not charge the battery as fast as the battery is draining which in turn will leave your car battery fully drained. Therefore, look out for a faulty charging system as if not been taken care of, it will drain out the battery even while driving and you will end up being stuck in the middle of nowhere.

Corroded or loose battery connections

Sometimes the positive and negative terminals connected to the battery might become loose or corroded over time because of which the battery fails to transmit its power to the engine and as a result, you have trouble starting the car. Henceforth it is advised to check for corrosion at regular intervals and get the battery cables replaced if you find them corroded, as simply cleaning out the rust won’t help.

Excessive short drives

Cranking the engine takes an enormous amount of power from the battery. As mentioned earlier, the alternator recharges the battery while driving. But in case of frequent short drives, the alternator does not get enough time to recharge the battery completely before you turn off the engine and as a result, the battery drains out all its power. That’s why it’s been said that in the long run, excessive short trips can minimize your battery’s lifespan.

Old battery

If you notice that your car battery is dying quickly even after a jumpstart, it means that the battery is worn out and it’s time to bid goodbye and get a new one. The average lifespan of a battery is about 3-4 years post which it loses its recharging capabilities. In such a case, the battery does not hold a full charge well and no matter how many times you try to revive it, it will drain all its power again.

The bottom line is, even if you maintain your car battery at home properly by keeping all these above mentioned precautionary measures in mind, the battery has to die after a certain amount of time. If you think you take good care of your car and do not practice anything which might damage your car battery then the only explanation left to consider is that the battery has crossed its deadline and it’s time for a battery replacement.
