A Complete Guide to the Different Types of Car Batteries

Do you know that most motorists can’t tell their car battery type until it breaks down? Just like any products available in the market today, not all batteries are created equal.

The battery plays an integral role in the life of any car. Almost everything in your car that makes it start or run is powered by electrical energy stored in the battery. But how do you know  your battery supplier is giving you the right one?

In this article, we’ll take you through various types of car batteries and give you tips for choosing the correct battery.

Lead Acid Car Batteries

Lead acid batteries are the most common types of batteries used in vehicles today. It’s important to know that these batteries aren’t actually made of lead.

They get their name because of the material it contains called lead plates, which intercalate with sulfuric acid.

These plates also serve as two electrodes where electrochemical reactions take place. The acid can power the engine because of a chemical reaction between the electrodes and other substances contained within the battery itself.

AGM Car Batteries

Absorbed Glass Mat batteries are similar to lead-acid batteries in terms of design. But there are two significant differences:

First, AGM batteries have no liquid electrolyte solution inside. Instead, they have a synthetic fiber mat soaked with sulfuric acid, which serves as an electrolyte.

Second, they’re completely sealed. You don’t have to worry about checking the specific gravity or adding water when it gets low.

Since these batteries are maintenance-free, you can’t carry spare acid or extra plates. To compensate for this, most batteries have a larger ampere-hour rating than standard SLA batteries.

Lithium-Ion Batteries

Lithium ion batteries are now the go-to for powering hybrid and electric vehicles. Their durability and power density make them ideal green energy sources. It’s suitable for people who want to switch their vehicles to green energy.

Lithium can store more energy per volume as well as maintain near-constant voltage throughout its life cycle. Li-ion cells offer some major advantages over other battery types.

Yet, there are still some factors that need to be considered, including safety concerns.

Valve-regulated Lead Acid Batteries

Valve regulated lead acid batteries, or VRLA batteries, are sealed instead of vented. They don’t emit flammable hydrogen gas when charging.

They also have a valve that regulates the amount of oxygen that’s released into the cells. The primary advantage of these types of batteries is the reduced chance of a thermal runaway.

This is even if a puncture occurs in one part of the battery while charging.

However, if any damage occurs to these valves, you’ll need to replace them for proper operation and maintenance purposes. This can add additional cost and labor time. Therefore, try your best to avoid physical damage to these valves.

Starting, Lighting, and Ignition Batteries

Starting light ignition or SLI batteries are not used for deep cycle purposes. Besides, they don’t have the same level of battery life as an AGM battery.

These batteries are designed to deliver a more powerful burst of energy for a short duration when starting up your car.

The SLI batteries are often found in hybrid vehicles or mild electric cars. They help improve fuel efficiency and reduce emissions at low speeds. Moreover, they can withstand repeated charge cycles without experiencing swelling or degradation over time.

Unfortunately, if one cell gets punctured while charging, all cells will likely be damaged somehow. That’ll force you to replace the entire battery.

Since they’re used for short periods, you can top off their water levels after charging. This way, they won’t go completely dry.

They need to be topped off with distilled water every time you charge them. But why distilled and not drinking water? Distilled water has some additional minerals that can help replenish some of what was lost.

When adding new liquid, don’t fill any gaps until the top is flush with the rest of the battery. It can cause an air bubble effect on one side if you add too much at once. Allowing air bubbles will affect cell balancing and will decrease the battery life.

What to Look for When Buying Car Battery?

When replacing or buying one for your vehicle, there are certain factors you need to look for. Here are factors that can help motorists choose the best car battery types:

Determine Your Needs

When buying car batteries, first establish your needs. How often will you be using the vehicle? Do you want a long-term solution or just a temporary one?

The answer to these questions will determine the type of battery that suits your budget and requirements. A long-term solution requires a maintenance-free battery.

Space Under Your hood

The space under the hood determines the size and design of the battery that’ll fit into your car. Make sure you have ample room to accommodate a new one before choosing a specific model.

Not having enough space means having to get rid of the old battery before initiating a replacement procedure. This entails laborious steps to remove old batteries, especially if they’re well-secured.

Inquire About Warranty

This is very important because it gives you an idea of how long the company will be in business. It also shows if the manufacturer stands by their product.

Read the warranty terms and conditions carefully. If the battery fails within the first year, you shouldn’t be charged for a new one. However, if it breaks down after a year or two, then you’ll have to absorb its replacement cost.


Before settling on a specific price range, do extensive research to ensure you’re getting the best deal. What do you do if you cannot afford to buy a battery with the exact specifications?

It’s imperative that you opt for one that’s close enough and meets most of your needs.

Check Online Reviews

Look at how other people have reviewed the product on third-party websites. If it’s a reputable brand, then you can trust their product and services.
