7 Common Car Battery Problems and How To Fix?

Common Car Battery Problems

Car batteries are mostly rechargeable batteries that are made of lead metal plates that are used to supply electric current to the vehicle.

It is used to power up the starter which in turn is responsible for starting the engine. After starting the engine, the rest of the electric system is powered through the alternator.

Though the batteries occupy very little space and are quite efficient, with it come to a lot of problems.

Among the car problems, it was reported by ADAC that, about 52% of the breakdowns of cars in 6 years or more is due to batteries.

Some of the most common car battery problems are listed below:

  1. Loose Terminals/Posts

In a battery, there are two terminals or post; one is the negative and other the positive. These are attached to specific parts of cars via cables and sometimes due to some factor the connection breaks.

There may be several reasons as to how that happens and the most common one among them is that the bolts or screws holding that are used to attach the cables to the posts become loose and current cant flow through them.

Corrosion on the terminals can also lead to this problem. Moreover, sometimes moving the car over a rough and bumpy road can also cause the connection to loosen up and to break the connection.

  1. Headlights

One of the common causes of car battery failure is leaving the headlights on. The headlights or even any other kind of dim light may end up draining all your battery overnight.

The best approach, in this case, is always correct to check the lights before leaving the car. In case the battery is dead, and the car isn’t starting, we can charge the batteries using a trickle charger.

Trickle chargers are left on the battery, and they slowly charge the batteries. The trickle charger is also quite helpful in case you don’t want to use the car.

In such a case it will keep your batteries charged, so if in case of emergency the battery would be charged.

Moreover, the trickle charger also prevents the depletion of charge from the battery which happens a lot usually.

There are different types of trickle chargers available in the market and the period for which it should be left on the battery posts also varies among them.

  1. Battery Life

On average the battery life of a car is 4 to 5 years in case of batteries commonly used which are made up of lead.

After this time the battery is unable to support the car, and it will not be able to start.

Moreover, other factors like drainage even as small as radio leak may damage the battery life of a car.

  1. Charging Issues

In some cases when the car stops running when you’re driving or randomly when you start up the engine, then there might be a chance that the problem is because your battery isn’t being charged correctly.

  1. Corroded Diode

We know that the alternator is responsible for providing current to the electric equipment in the car after turning on its engine.

If due to some reason, its diode ends up getting corroded it will extract current from the battery even when the battery is turned off.

Hence in a short interval of time, the battery will become useless.

  1. Severe Weather Conditions

The car battery is immensely affected in harsh weather conditions both in summers and winters.

The reason is when the temperature becomes either too hot or too low the lead in the batteries starts to form lead sulfate which drains more charge from the battery, reducing the life span of your battery.

Moreover, extreme weather conditions are also responsible for some other car problems.

  1. Low Fluid Level

Though most people would disagree with including this factor, in reality, reduced levels of electrolyte present in the batteries cause more time for the batteries to charge and also quick drainage of the battery charge.

The interesting fact about this factor is this is one of the most significant contributors since people tend to neglect these things and end up paying more for them.

The best approach is to check the fluid level about every two weeks in case you use the car quite frequently and about a month if used less.
