A battery is the most important part of your motorcycle. It helps to start your motorcycle when you turn on the ignition. Without a good battery, you can’t get your bike started and it is vital to pick the right volts of battery for your motorcycle.
So, How Many Volts In A Motorcycle Battery? Motorcycle batteries come in a variety of voltages, most motorcycle batteries range from 6 to 12 volts. But some are as high as 14 to 16 volts.
In this article, we’ll discuss how motorcycle battery works, how to test battery voltage, key differences between 6v and 12-volt batteries, and much more. So keep reading till the end.
How Does Motorcycle Battery Work?
First, let’s understand how these batteries work. A motorcycle battery is a lead-acid battery, which means it uses lead and sulfuric acid to produce electricity. A lead-acid battery has two terminals, a positive (marked ” + “) and a negative (marked ” – “). The positive terminal is usually red, while the negative terminal is usually black.
When you connect your motorcycle’s spark plugs to the correct terminals, an electric current flows through the spark plugs. This ignites the mixture of air and fuel in the cylinders. This produces the power that makes your motorcycle run.
Now that we know how motorcycle batteries work, let’s discuss how to check the voltage on your battery.
How to Determine the Voltage of Your Motorcycle Battery?
If you take a look at your motorcycle’s battery, you will notice that there are two numbers listed on it. These numbers indicate the voltage of the battery.
To determine the voltage of your motorcycle’s battery, you will need to take a look at both numbers.
The first number is the nominal voltage, which tells you the average voltage of the battery. The second number is the cold cranking amps (CCA), which tells you the amount of current that the battery can deliver for 30 seconds at 0 degrees Fahrenheit.
If you take a look at the two numbers and compare them, you will notice that the CCA is always lower than the nominal voltage. For example, a 6-volt battery may have a nominal voltage of 6.5 and a CCA of 200. This means that the battery can deliver 200 amps for 30 seconds at 0 degrees Fahrenheit.
Best Ways to Physically Test Battery Voltages
You can use a voltmeter or a multimeter to measure the potential difference (p.d.) between the battery’s terminals, or positive and negative terminals, to determine the voltage of your motorcycle battery.
Testing Battery Volts Using Voltmeter
Step 1: Locate the Motorcycle Battery:
The majority of motorcycles have batteries behind the seat or saddle, so look there to find them. Elevating the seat would be necessary to reach the battery.
Step 2: Clean the terminals
Corrosion may have accumulated around them, preventing the cable from making contact with the terminal. If there is debris surrounding the terminal cover, remove it and clean it with a wire brush and battery cleaning solution. Baking soda and a little water can be used to create a cleaning solution if you do not already have one.
Step 3: Terminals connection
Connect to the terminals by connecting the voltmeter’s positive lead to the battery’s positive terminal and its negative lead to the terminal on the other side of the battery. Make careful to link the positives before the negatives.
Step 4: Verify the reading
Fully charged batteries for 12V systems should register between 12.6V and 12.8V. Anything above 12.4V and below 12.9V on the voltmeter indicates a healthy battery. An overcharged battery was indicated by anything on 12.9V and higher. Turn on the headlights at full beam to use up some of the battery power. Battery recharge is required if the voltage falls below 12.4V. If it is below 12.2V, a gradual trickle charge is advised to cut down on extra heat.
Testing Battery Volts with a Multimeter
Step 1: Configure the multimeter
After setting the voltage mode of the multimeter, connect the positive lead to the positive terminal of the battery. Next, join the multimeter’s negative lead to the battery’s negative terminal. Ensure that the resting voltage is 12.5V.
Step 2: Recall the reading
Start the motorcycle’s engine after putting it in neutral. When you start the engine, a good battery’s voltage will drop to roughly 11 volts. If it drops below 9.5 volts, the battery needs to be changed because it is damaged.
Is Motorcycle Battery 6V Or 12V?
The majority of motorcycles on the road today have 12-volt batteries. 6-volt batteries are less common and are generally found on older model bikes. The voltage specification is the same for both types of batteries, but the amp-hour rating will vary depending on the manufacturer and model of the motorcycle.
Key Differences Between 6v and 12v Batteries
The most obvious difference between 6v and 12v motorcycle batteries is the voltage. As the name suggests, 6v motorcycle batteries have a voltage of 6, while 12v motorcycle batteries have a voltage of 12. But what does that mean for you and your bike? Here’s a breakdown of the key differences between 6v and 12v motorcycle batteries:
1. Amperage
6v motorcycle batteries have lower amperage than 12v motorcycle batteries. This means that they can’t provide as much power to your bike’s electrical system.
2. Starting power
If you live in an area with frigid winters, then you want a battery with high starting power. That’s because cold weather can drain a battery’s power more quickly. For this reason, 12v motorcycle batteries are typically better suited for cold-weather starting than 6v motorcycle batteries.
3. Size
Another key difference between 6v and 12v motorcycle batteries is size. Because they have twice the voltage of 6v batteries, 12v batteries are usually larger and heavier. This can be a problem if you’re trying to save weight on your bike.
As 12v batteries are more powerful than 6v batteries, they’re a suitable choice for larger motorcycles.
4. Price
Lastly, price is always a consideration when choosing any type of battery. In general, 12v motorcycle batteries are more expensive than their 6v counterparts.
It’s up to you to decide which type of battery is right for your motorcycle. If you’re not sure which one to choose, ask a professional or someone who knows about motorcycle batteries. They’ll be able to help you make an informed decision.
What are the benefits of a 12v motorcycle battery?
A 12v motorcycle battery offers several benefits over other types of batteries. They are more powerful, provide longer life, and can be used in a wider variety of applications. Additionally, 12v motorcycle batteries are less likely to leak acid or cause other damage to your vehicle.
One of the most prominent benefits of a 12v motorcycle battery is its increased power. This allows you to start your engine more quickly and easily, which can be a lifesaver in an emergency. Additionally, the extra power can help you get out of tough situations when other batteries may fail.
Another significant benefit of a 12v motorcycle battery is its long life. These batteries are designed to last for many years, so you won’t have to replace them as often as you would other types of batteries. Additionally, they require less maintenance than other types of batteries, which can save you time and money.
Moreover, a 12v motorcycle battery can be used in a wider variety of applications than other types of batteries. This means that you can mount them in a wider range of vehicles, including motorcycles, ATVs, snowmobiles, and even boats. This versatility can make them a suitable choice for those who need a battery that can be used in multiple applications.
Is it Possible to Replace a 12V Battery with a 6V Battery?
A 6-volt battery can replace a 12-volt battery, but doing so is not recommended. But do not substitute a 6v battery for a 12v battery if you want to get the most out of your moped or motorcycle.
A 6V battery is made to start a cold engine, whereas a 12V battery is made to power motorbike electrical accessories. If equivalent accessories are fitted on a 12V system, the current demand will be somewhat less.
But neither your battery’s performance nor its lifespan will be optimized by doing this. As a general rule, unless the manufacturer specifically advises it in an owner’s handbook, you should never use a 6V battery on a 12V motorcycle system.
