How many volts is a motorcycle battery – 12v or 6v Better?

A good deal of motorcycle owners knows how important it is to keep their bikes well-maintained. However, they’re often left wondering how much juice their battery needs.

How many volts is a motorcycle battery? The standard is 12v. But if you’re planning to use a new battery to power a new ride, you’re going to want to make sure you’re getting the most out of that investment. Let’s find out in this article. 

First, let’s answer the question, “Is Motorcycle Battery 6V Or 12V?” Then, we’ll add some information.

Well, the answer is quite simple. A motorcycle battery has around 12 volts. The voltages of the battery in a motorcycle vary from 12 Volt to 18 to 24 Volt. But the majority of the time, a bike will have its battery voltage as 12 Volts.

Motorcycle Batteries: What You Need to Know

If you own a motorcycle, you’re probably well aware of the importance of a motorcycle battery. But just in case you’re not, here are the top five things about motorcycle batteries. They’re a big part of keeping your bike running for miles down the road.

 1. Startup reliability thru high CCA

Motorcycle batteries are designed to provide enough power to start a motorcycle when it’s cold out. Look for the Cold Cranking Amps (CCA) value. This number should be between 500 and 800. The CCA operates at 0 degrees Fahrenheit which means you can start your engine despite the cold temperature.

2. Sealed Batteries are Better

It’s essential to get the correct battery for your motorcycle. You don’t want to pay to replace your battery every time it dies. Look for AGM (Absorbent Glass Mat) or gel motorcycle battery products. They will have a seal that will protect the terminals from corrosion.

3. Purchase a replacement kit to keep the battery free from vibration.

You may want a better battery for your motorcycle to have a longer service life. Check the size of the battery against the compartment. Make sure it’s tightly secured and doesn’t move around.

4. Motorcycle and E-Bike batteries are not the same.

There are many different types of batteries. To avoid the mistake of buying the wrong battery, consult with your mechanic.

5. AGM Batteries are the Best for Motorcycle

AGM batteries are the best battery for powering up a motorcycle. They are available in varying sizes and power levels. They provide you with versatility on any bike model you own.

Three simple ways to check your battery

When a battery is new, it’s very reliable. But if you use your battery for more than a year, it will lose its ability to hold a charge.

You can’t use all the juice upfront and then use the rest later. That’s not a tank of electricity. Batteries don’t “leak” power like water can. A plastic box encloses a lead battery acid; this contains a delicate balance of chemicals that are ready to interact with one another and generate power when a load is applied. Batteries that don’t hold their charge long enough are usually a chemical issue.

How do you test a battery?

1) Inspect the Battery

You can tell if your battery is busted by looking at it. There are a few things to check:

  • Bump or bulge
  • A break in the plastic
  • Broken terminal
  • Leaking
  • Discoloration

The first step is to check if you have a broken battery. You should be able to pull it out of the motorcycle easily. If the terminals are broken or loose, you should take the battery out immediately. Batteries with cracks, split, and holes are dangerous and should not be used.

Flooded cell batteries have a large amount of water within them. Maintain the water level at all times. If the water is low, the battery will not work. If the water is too high, it can cause the plates to dry out.  It is vital to charge the battery with the correct amount of fluid to prevent sulfation. If the battery has fluid in the cells, but the color is light or clear, this is an indication that the battery is safe to use. If the battery has no fluid in the cells, this is also an indication that the battery is not safe to use. Even if only one cell is brown, the battery as a whole is rendered ineffective. In this situation, it is imperative that you replace your battery.

 2) Voltage Reading

You can use a voltage tester to check your batteries to see how many volts they have; this will help you determine how much power they have and when to recharge them.

  • A battery that reads 0 volts is experiencing a short circuit.
  • A dead cell in a battery doesn’t affect the charge of other cells.
  • A fully charged battery with a 12. 4 or less voltage is sulfated.

Sulfation decreases the battery’s ability to hold a charge, and it discharges faster than a non-sulfated battery. You can charge a sulfated battery, but it won’t fully recover to a healthy state.

3) Load Test the Battery

Load testing a battery is better done at the shop; they have the tools and expertise to see How many volts is a motorcycle battery has and can give you feedback immediately. However, since it’s easy to do, you can also test your battery at home.

For accuracy, the battery has to be fully charged and left unused for 12 hours, which will eliminate the residual charge. 

Remove the seat cover and expose the terminals of the battery. Do not disconnect your battery—start your motorcycle. 

Hold the voltmeter’s prongs against the right terminals of a battery. If the battery is in good condition, it will sustain a voltage range between 9.6 and 10.5 volts for a continuous duration of 30 seconds without losing voltage. If the voltage reading drops, you might have a discharged battery. Whenever the voltage falls below 9.6 volts, the battery must be replaced.

Alternatively, if your motorcycle has a cigarette lighter socket, you can purchase a 12V Dual Car Cigarette Lighter Adapter with a USB Charger and  Digital Voltmeter. You can immediately see the reading. 


I hope this helped you learn more about your battery. I recommend checking your battery at least once a month to see if it shows the correct voltage and has no signs of physical damage. I would also recommend replacing your battery every two years or every year if you are riding frequently.
