What Are the Different Types of Car Batteries?

Projections show that the global automotive battery market will reach a value of $65.62 billion by 2028.

When replacing a car battery, you have several options. With all the types of car batteries available, picking the right one isn’t always easy. If you want to be sure you’re purchasing the best battery for your needs, then you should have an understanding of what the different choices are.

For a run down of the types of automotive batteries available, keep reading.

Calcium Batteries

These are a type of lead-acid batteries that have calcium components on the negative and positive plates. They use lead-antimony, which is cheap and easy to source, making them low cost and low maintenance.

They’re easy to charge as they don’t need a high voltage. Calcium batteries are some of the best car batteries for electric vehicles, but they may one day also be just as suitable for traditional cars.

If auto battery lifespan is a major concern, these are a good choice. They typically last longer than other battery types and don’t need any maintenance.

Deep Cycle Batteries

These are one of the most common types of automotive batteries available. You can get these from many suppliers, such as The main benefit is that they have a high capacity when in use.

Deep cycle batteries can be discharged by about 80%, which is more than most other types. They also tend to perform better overall. If buying one of these, you want to make sure the plates are solid lead – some are made with sponges that don’t perform nearly as well.

Wet Cell Batteries

Wet cell batteries are cheaper than most other types of automotive batteries. They’re made using a combination of lead, water, and sulfuric acid to create the electrolytes.

A major downside of wet cell batteries is that they aren’t the most energy-efficient. They’re not seen much in modern vehicles as they can’t match the high energy demands.

AGM Batteries

Absorbed Glass Mat batteries can meet much higher energy needs, which has made them far more popular in recent years. They’re similar to flooded lead-acid batteries, but have the electrolyte engrossed in glass mats rather than flooding freely on the plates.

They’re a bit larger than other types and perform better in vehicles with high energy needs. AGM batteries are designed in the same way as VRLA (valve-regulated lead-acid) batteries, which use a valve regulator to control the pressure.

EFB Batteries

Like AGM batteries, these are ideal for modern vehicles that have high energy requirements. They’re improved versions of flooded/wet batteries, giving better performance and more durability than older cell types.

The cyclic durability is much better, which is ideal for stop-start applications. An EFB battery will often get 2-3 times as many starts than a traditional flooded battery.

Deciding Between Types of Car Batteries

There are many types of car batteries, and if you want to get the most out of your vehicle, you should pick the right one. Think about your usage and the demands of your vehicle, as well as your budget, to help decide which type is best for you.
