A Guide to the Most Common Car Battery Types

Posted: July 28th 2023

The electrical system of your automobile is powered by the car battery, which is essential to the safe and dependable operation of the system. Car batteries come in a variety of forms, each with its unique benefits and factors to consider.

When it comes to replacing or updating your automobile battery, knowing the distinctions between different battery types will help you make an informed choice. This article provides a detailed breakdown of the most common types of car batteries and the implications of each one.

The Most Common Types of Car Battery

The most typical automobile battery types are as follows:

Lead-Acid Batteries

For many years, lead-acid batteries have been the standard option for automotive applications. They are renowned for being reasonably priced and durable, most distinguishable by their lead plates that undergo a chemical reaction with an electrolyte solution of sulphuric acid and water.

Lead-acid batteries often come in two different variations: flooded and sealed. Lead-acid batteries that have been flooded need to have their electrolyte levels checked and topped off with distilled water regularly. Maintenance-free batteries, commonly referred to as sealed lead-acid batteries, are aptly named as maintenance-free due to the fact they are sealed to avoid potential leaks.

Absorbent Glass Mat (AGM) Batteries

Batteries with an absorbent glass mat (AGM) have grown in favour in recent years due to their improved performance and adaptability. The electrolyte is held in place by an extremely porous microfibre glass mat used during their construction.

This design offers several advantages, such as higher vibration resistance, better-cranking power, quicker recharging, and longer cycle life.

AGM batteries are also renowned for their capacity to produce steady power, qualifying them for use in cars with sophisticated electrical systems-for example, the start-stop technology that automatically shuts the engine down at a traffic stop.

Gel Cell Batteries

A different variety of sealed lead-acid batteries, gel cell batteries, use a gel electrolyte as opposed to a liquid electrolyte. The thick, jelly-like gel electrolyte remains immobile, making the battery spill-proof and vibration-resistant.

Due to their deep cycling characteristics, gel cell batteries are well-suited for applications that call for frequent charging and discharging. However, compared to other battery kinds, they could have considerably less "cranking power" or "cold cranking amps (CCA)." This term refers to the amount of electric current a battery can deliver when starting an engine at colder temperatures.

Lithium-Ion (Li-Ion) Batteries

Lithium-ion batteries are gaining popularity in a variety of fields, including the automotive industry. Compared to conventional lead-acid batteries, they have several advantages, including improved energy density, a lighter weight, and a longer lifespan.

Additionally, lithium-ion batteries can sustain a constant voltage throughout their discharge cycle, resulting in a quicker recharge time. The use of these batteries in automotive applications is still developing, and they are often more expensive than other types of batteries.

Lithium Iron Phosphate (LiFePO4) Batteries

Batteries made of lithium iron phosphate (LiFePO4) are a form of lithium-ion battery that is specifically made for use in automobiles. They provide good thermal stability, a long lifespan, and high energy density.

In addition to having a lower risk of thermal runaway and a reduced likelihood of an explosion or fire, LiFePO4 batteries are renowned for their safety qualities. Additionally, these batteries are portable and charge quickly. However, their cost is often higher than that of other types of car batteries.

The electrical needs of your vehicle, your budget, and the required level of performance all play a role in selecting the best car battery type.
