Everyone knows that there is a battery in the car which provides power to electrical equipment.There are a lot of things you might want to know.In this article, we will talk about different types of car batteries and car battery life. No one wants a surprise in the form of a dead battery. Well, there are a lot of symptoms that will tell you that your battery needs replacement. These symptoms can help you protect your car battery life.

We should know about the function of the car battery then we will be able to approximate the car battery life.


Functions of a car battery


Car battery converts chemical energy to electrical energy. It provides a sudden jolt of electric charge that the car requires for starting the engine. Apart from that, it also delivers the necessary electric potential to the electric components of your vehicle.

All the car batteries provide charge to electric components for a few minutes as, after the engine starts, there is a component known as an alternator. This alternator takes over the charging duty, which means now this alternator will provide the necessary electrical charge to all the electrical components. Moreover, it also charges the battery. In this way, your battery keeps on working for years.

So the functions of car batteries are:


  • Providing electric current jolt for starting of the engine
  • Providing electric current to electric components when the engine is off

Types of car battery


Almost all the batteries work the same way that is they convert chemical energy to electrical energy. Car batteries have a metal plate, acid, and distilled water to perform that chemical reaction. The metal plates consist of lead, and the acid is sulphuric acid. The lifespan of a car battery depends on all these components.

There are mainly six types of batteries:


  • Flood cell battery

These are the simplest of car batteries. Flood cell batteries are most commonly found in entry-level vehicles and are cheap. They may or may not require service and maintenance. The lifespan of these car batteries is comparatively low. For maintenance purposes, these batteries require distilled water top-ups.


  • Enhanced flooded battery

These batteries have a better performance. Their design delivers a more frequent electric charge. Cars that equip engine start/stop switch use these batteries.

The life of these car batteries is much better than flood cell batteries.


  • Calcium batteries

These batteries are almost like the flood cell batteries but provide more electric charge and have longer battery life. These batteries have calcium added to the metal plates. This calcium makes them more efficient and increases the car battery life.

Adding calcium also decreases the formation of hydrogen.


  • Gel battery

As the name suggests, these batteries contain gel. The metal plates of these batteries suspend in gel instead of liquid.

This gel makes the battery more resistant to any disturbance or shock. Adding gel instead of liquid also makes these batteries leakproof.

As the gel has high energy absorbing properties, the gel battery can handle extreme temperatures.


  • Absorbent glass mat battery

This battery also has lead metal plates and sulphuric acid. It is one of the most advanced lead-acid batteries. These car batteries are high-performance batteries and can deliver the electric charge to more demanding electric components.

Absorbent glass mat battery can be repeatedly charged or discharged without any decrement in performance. The life of these car batteries is much higher than the previous types.


  • Lithium-Ion battery

Most electric drive vehicles equip lithium-ion batteries. These batteries can discharge and recharge without any problem. These batteries are perfect for electric vehicles as these vehicles need frequent electric recharge. A lithium-ion battery is a lightweight battery. They are about 80% lighter than lead-acid batteries and are quick to charge. These batteries require maintenance.

Since they deliver high-performance, they are the most expensive of all battery types.

The lifespan of lithium-ion batteries is the best among all its competitors.


Lifespan of car batteries


Manufacturers provide an average battery life which is about 3 to 5 years. Flood cell batteries have a lifespan of about three years. The maximum car battery lifespan is of lithium-ion battery.

These batteries have an average lifespan of five years. These are just the average car battery lifespan and may vary depending upon a lot of factors.

Have a look at all those factors.


Factors that affect car battery life


Several factors may affect your average car battery life.


  • Defective Alternator

An alternator is a device that takes over the charging duties of the battery as soon as the engine starts.

After the engine start, the alternator keeps on charging the battery. In case the alternator is defective, the battery will not charge efficiently.


  • Driving style

If you frequently drive over a short distance, your battery didn’t get enough time to be charged. In addition to this, frequent stoppages of the engine draw a lot of power from the car battery. All this will lead to a decrement in the average car battery life.


  • Using electrical components when the engine is off

Your car’s electrical parts like ignition, headlights, taillights, phone charger require an electric charge. When the engine is on, the alternator delivers this charge, but when the engine is off battery provides this charge. 

Hence, you should not use electrical components while the engine is off.


  • Climate conditions

Climate conditions such as humidity and high temperature also affect battery life. High temperature may cause evaporation of battery fluids, and humidity may result in corrosion. All this will significantly lower the car battery life.




Your car battery life will decrease if you use the electric components of your car while your car engine is off.

The car battery lifespan mentioned above is the manufacturer claimed battery life and may vary depending upon many factors. In most cases, the car battery life ranges from 3 years to 5 years.
