Why a Maintenance Free Battery Is a Smart Purchase for Your Vehicle


In Asia, it’s expected that the compound annual growth rate of the automotive battery market will be about 6.5% from 2019 to 2024. As you can see, the market is highly competitive, with companies trying to outperform one another.

One such innovation that’s risen from this competition is the maintenance-free battery. This type of battery has been created to make the lives of drivers like you easier.

Read on to find out why a maintenance-free battery is a smart purchase for your vehicle.

The Tech in Traditional Car Batteries

Before we tackle the advantages of maintenance-free batteries, you should first understand how a traditional car battery works. That way, the benefits of the maintenance-free type will be more obvious.

The automotive car battery was invented in 1859 by Gaston Plante and uses lead-acid. It has 2 terminals with sulphuric acid on one side and distilled water on the other. This is what powers the battery.

Because the electrical reaction depletes water (it becomes hydrogen and oxygen gas), this requires you to keep adding water to the battery to ensure it keeps running.

Benefits of Choosing a Maintenance-Free Battery

With a traditional car battery, you’ll have to perform maintenance on it so it doesn’t die on you. However, as the name suggests, a maintenance-free battery doesn’t require you to do so.

This is because this type of battery uses terminals made of lead and calcium. It reutilises the hydrogen and oxygen gas released (oxygen recombination cycle), which allows the closed system to be self-sustaining.

That’s just one of the main benefits of choosing a maintenance-free battery over a traditional one. Read on to find out more.

You Don’t Have to Deal with Spills

When you’re refilling the car battery with distilled water, you have to open it up to do so. As a result, you have to deal with potential spills, which can be damaging.

The sulfuric acid in the battery can irritate and even eat away your skin. If you get it on your clothes, the cloth can get ruined as well.

With a maintenance-free battery, you won’t have to deal with this hazard anymore.

There Is More Resistance to Corrosion

When you have to constantly fill up your car battery with water, you risk overfilling it. The leaked acid can then cause corrosion on your battery, which may interfere with its performance. This can be a hassle to deal with, and you may have to spend extra time and effort to get rid of said corrosion.

Because you don’t have to refill maintenance-free batteries and it’s in a sealed system, there’s very little chance of any acid leaking out.

There are also corrosion-resistant grids inside. Plus, the calcium in the battery makes it inherently resistant to corrosion. This means you won’t have to deal with breakdowns due to this issue, nor will you have to clean it off.

Lower Chances of Overcharging

When a car battery overcharges, you run the risk of it dying. This is because the liquids inside will start to boil, and the battery will become hot. As a result, it might start melting or even swelling.

A maintenance-free battery has lead and calcium terminals, which reduce the chance of overcharging. This is also what allows the oxygen recombination cycle to happen.

Lower Chances of Overheating

If a car battery overheats, then it’s no good. While overcharging can cause this to happen, other factors may contribute to overheating as well.

The maintenance-free battery is carefully designed with the issue of overheating in mind.

For instance, the RB maintenance-free battery has Double Ventilation Technology. This prevents an excess of both pressure and heat from building up through the use of an intricate ventilation process. There are also Rapid Cool Down Separators, which help maintain an optimal temperature for the battery.

With these pieces of technology in place, you get a battery that won’t overheat, nor will it decrease in performance when you least expect it.

It Lasts Longer

Because maintenance-free batteries utilise the oxygen recombination cycle, this means there’s minimum water loss. These are completely sealed, except for a tiny hole used as a vent. So again, the water loss will be negligible.

As a result, maintenance-free batteries will last for much longer than traditional car batteries. Its slow self-discharge rate makes it so you won’t have to replace your car battery as often.

Your Car Starts up Quicker

When the weather gets colder, it can become more difficult and longer to start up your vehicle. Struggling to properly start up your car can lead to inconvenient issues, such as getting to school or work late.

By choosing to use a maintenance-free battery, you won’t have to struggle anymore. This type of battery has superior cranking and high reserve capacity. What this means for you is higher cold cranking startup.
