Top 7 Best Dirt Bike Battery [Expert Review]

Are you looking to buy a new dirt bike battery? Dirt bikes don’t necessarily need batteries to work unless they have electric components. However, more manufacturers are now releasing dirt bike models with electric parts like electronic fuel injection and electric starters. 

While most dirt bike batteries—especially lithium batteries—will last long, they won’t last forever. If it keeps losing charge or you’re struggling to fire up your bike, you need new batteries. But with so many options in the market, how do you choose the best dirt bike battery? 

I’m a dirt bike enthusiast with over a decade of experience reviewing different dirt bike models and accessories. I have selected seven of the best dirt bike batteries according to their features and benefits. Read on to find out which dirt bike battery you should buy.

My top choice is the Antigravity ATZ-10 lithium-ion battery. This battery features excellent cranking power, a full battery management system, and fast charge. It also comes with a 50% extra battery pack, which makes it more powerful and lasts longer than standard dirt bike batteries.

The ATZ-10 also features a built-in jump start button which helps you restart your battery when it dies. Although it’s more expensive than lead-acid batteries, it also packs more power, charges faster, and last longer.

Just like its successor, the YTX4L-BS is an AGM battery. This means it has many qualities associated with AGM batteries like electrical reliability, maintenance-free, and lightweight. 

It comes with 12 volts of battery power and a three amp-hour capacity. This gives you 62 cranking amps which don’t quite match up with lithium-ion batteries but are respectable for a lead-acid battery. It is still enough power to start your engine quickly in moderate temperatures. 

This battery also comes with gel electrolytes. Hence, it can absorb vibrations and has resistance to discharge death.

The YTX4L-BS also has smart technology features like an intelligent chip and digital display. The display shows the battery voltage and will display a warning alert when the voltage is low. 

According to the manufacturers, this battery is powerful enough to start engines of popular dirt bikes like the Husqvarna CC450, Kawasaki CC400 E/XC Racing 4-Stroke, and Honda CRF125F. However, some users believe they may have exaggerated a bit. In reality, it can power a few 250cc engines and everything else below. Any belief that it can power higher CC engine bikes is, however, far-fetched. 

How to Maintain Dirt Bike Batteries

Dirt bike batteries usually run on little maintenance. However, you may still want to check your battery occasionally. 

Here are some simple maintenance tips to increase your battery’s life span and guarantee optimal performance.

1. Check the Electrolytes Level

The electrolyte level in your battery lowers over time. This could expose and damage the plates in the battery cell. You should check the electrolyte level once every month. Maintaining the electrolytes level of your lead-acid batteries ensures it functions properly. This maintenance tip is only necessary if you own a lead-acid battery.

2. Cover up the Battery Properly

Extreme weather conditions can have a damaging effect on your battery. Battery efficiency reduces when you store it in a place that is either too hot or cold. Ensure your battery is stored at a controlled temperature to maintain its condition.

3. Charging Memory

Lead-acid batteries will often not accept a charge that is less than what it has experienced. This is called the charging memory effect. You should use a charger specifically designed for your battery. Do not opt for a cheaper version, espeically if the provided charger fails. So, ensure you charge your battery to full capacity before use.

4. Clean the Terminals

Over time, your battery terminals will accumulate acid and copper sulfate. This can make your battery overheat and prevent it from charging. Keep your terminals clean with a stiff wire brush, and rinse off with water. You can also mix baking soda and water to clean the terminals.

Buying Guide

The following are factors to consider when buying a dirt bike battery:

1. Buy Factory-Sealed Batteries 

Choose a battery that is factory sealed to cut down water loss or acid spill. You don’t need to perform regular checks or any water top-ups with factory-sealed batteries. This can save you time and effort. 

2. Cold Cranking Amps(CCA)

The cold cranking amps determine the battery’s ability to start in cold conditions. If you buy a battery with low CCA, your dirt bike engine might fail to start during some cold winter days. 

Cold-cranking amps also determine how quickly your battery can start an engine left inactive for a long time. Hence, choosing a battery with high CCA for optimal performance all year round is important. 

3. Power Rating 

When buying a dirt bike battery, ensure the battery has enough voltage and amp-hour capacity to start your bike. Higher voltage means the battery can start your bike in harsh weather conditions. If you own a 450cc dirt bike, a battery that delivers a power rating below 150 CCA may not start your engine in extreme conditions.

4. Compatibility

Some batteries won’t work for your dirt bike. Check your bike’s manufacturer’s guidelines for batteries before buying one. Also, check the battery manufacturer’s guide to see if your bike is ls one of the brands they support.

You should also check for the size and dimensions of the battery to ensure it fits into your dirt bike. 

5. Warranty

You do not want to purchase a battery without the manufacturer’s support. The longer the guarantee, the better your battery will serve you. Also, buying a battery with a warranty means you can easily return it if it doesn’t work or stops working after a while. 

FAQ

Final Thoughts

Dirt bike batteries provide the power you need to start your engine quickly. Lithium-ion and lead-acid batteries are the two major types available.  Generally, lithium-ion batteries are better than lead-acid batteries. They are safer, more powerful, require less maintenance, and last longer. But this doesn’t mean lead-acid batteries are terrible. Many powerful lead-acid batteries, especially AGM batteries, can compete with lithium-ion batteries, and I have listed some of them in this article. If you’re looking for the real deal, look no further than the Antigravity ATZ-10. It’s powerful, maintenance-free, charges quickly, and offers long battery life.
