Car Battery 101

From your fuel pump and headlights to your radio and onboard computer, your car’s battery is responsible for powering all your vehicle’s electronics. As your vehicle runs, it uses engine power to spin the alternator, which sends power to recharge your battery to ensure that it continues to run. As long as your engine runs, your battery is constantly recharged. However, your car battery’s biggest task is to start your engine. Starting your engine requires large amounts of battery power, especially when your engine is cold. 

Because starting an engine requires so much power, weakened or depleted batteries may not have enough capacity to complete the task, and that’s when you may find yourself unable to start your car. 

Signs of Auto Electrical and Car Battery Issues

By the time most electrical and battery issues are detected, it is usually too late. If you know what to look for, you can catch these issues early and have them resolved right away. 

Below are a few telltale signs of car battery trouble:

Warning Lights

One of the telltale signs that your vehicle is experiencing electrical or car battery issues is the car battery warning light. This red light usually indicates that your vehicle has detected issues with its charging system. Many times, drivers see this warning light and believe that their car battery needs to be replaced. However, a battery warning light usually indicates that the charging system itself is malfunctioning and the battery will be low, as a result. 

Slow Cranking

Slow cranking is another sign of a low or weakened battery. If you notice your engine is turning over slower than normal when you start your vehicle, it is possible that it may be time for car battery replacement. Car batteries last an average of three to five years. This is because as they age, they’re not able to hold as much energy as they once could. Toward the end of a car battery’s life, its energy capacity drops to a point where it can no longer hold enough energy to start your car.

Dim Headlights 

Dim headlights while your vehicle is running can be a sign of a low battery or auto electrical issues. Usually, your alternator is able to recharge your battery enough to operate its electrical features as long as the engine is running. However, if your car’s alternator cannot deliver enough power to your battery or there is an electrical issue that is not allowing your battery to receive the power it needs from your alternator, you may notice that your headlights are dimmer than normal.

Burning Rubber or Plastic Smell

Fluctuating currents through your vehicle’s electrical system can cause stress on electrical components and wires and even cause fuses to blow. If you notice a burning smell while your car is operating or shortly after starting your vehicle, this can be a sign that you have auto electrical issues that need to be addressed. 

Continuing to drive with auto electrical issues can result in the disabling of your vehicle or an electrical fire.

How Often Should Your Car Battery Be Replaced?

We recommend replacing your battery every three years to prevent being stranded with a dead battery. This ensures that your vehicle’s electrical components always have the power to operate normally without power fluctuations or losses. Fluctuations from a dead battery or jump-starting your car can cause electrical components to fail or fuses to blow.

In the recent past, the world has undergone many technological changes, with people becoming more innovative. This has led to the establishment of more functional and durable products than traditional ones. The AGM (absorbed glass mat) battery is an improved battery designed in the early 80s to replace the flooded lead-acid battery. The AGM battery requires little to no matienence, and it does not spill. On the other hand, a Flooded lead-acid battery is the kind of battery that has been widely used for over one and a half-century. They are also referred to as the wet cell battery for the liquid electrolyte found inside. The battery has been used for various applications, which has served until an alternative of AGM was found. Below are some differences between an AGM battery and a lead-acid battery.

Maintenance needs

The lead-acid battery contains an electrolyte inside that emits gasses. Therefore, the battery needs to be in a well-aerated and open area for easy maintenance and emission of gases. On the other hand, the AGM battery is maintenance-free and emits no gases. This makes it best suited for vehicles that use batteries in trunks and beneath the seats.


The lead-acid battery is prone to vibrations and forceful movements. Therefore, they are delicate and can easily break when exposed to such conditions for a long time. Thus, one must be cautious when mounting them to minimize these effects. On the other hand, AGM is made up of glass mats and battery plates that make the structure unbreakable. Furthermore, they make the battery stronger and resistant to shock and vibration.

Internal resistance and power output

Internal resistance in the battery results in its voltage output. Therefore, the lower the opposition, the higher the output voltage. The AGM batteries have a resistance of as low as two percent, thus having a high power voltage. On the other hand, flooded lead-acid batteries have a resistance of between ten to fifteen percent. This, therefore, gives the AGM an upper hand as more potent than other lead acid batteries.

Charging time

The lower internal resistance in the AGM gives them an increased rate of charging compared to the lead-acid batteries. The AGM is five times faster in charging than the flooded lead-acid batteries. Furthermore, the AGM responds to ample power demands meeting the demand easily than any other lead-acid batteries.

Lifespan and self-discharge

The AGM has a lower self-discharge rate that lasts longer than the flooded lead-acid batteries. The AGM has a lifespan of up to seven years if well maintained, compared to other batteries that last for three to five years. Therefore, the AGMs last longer and will serve you better than any other batteries.


From the differences outlined above, it is evident that the advancement of AGM (absorbed glass mat) battery has come with a lot of benefits as compared to the past when people only used one brand of batteries. Therefore, it is recommended to go for an AGM battery when possible as opposed to lead-acid batteries.
