How Long Does It Take To Charge A Motorcycle Battery?

Motorcycle batteries are a critical part of the bike and need to be in proper condition for the motorcycle to run. Most people know that you have to charge a battery before using it, but many don’t know how long does it take to charge a motorcycle battery?

It’s no secret that motorcycle batteries don’t last as long as car batteries. A motorcycle battery needs roughly 6 to 7 hours to fully recharge when the engine is off. If the engine is running, a motorcycle battery will fully recharge in about 5 to 6 hours.

In this blog post, we will cover how long it takes to charge a motorcycle battery and some methods to keep your motorcycle charged more smoothly. So read on for more information!

How long does it take to charge a motorcycle battery?

When the engine is off, it will take about 6-7 hours to charge a motorcycle battery from a full discharge. A motorcycle battery will take about 5-6 hours to charge from a full discharge if the engine is running.

When a motorcycle battery is not in use, it will gradually lose its charge and become dead. As you attempt to start your motorcycle after a prolonged absence. Therefore, it’s crucial to understand how frequently to charge a motorcycle battery.

This is assuming you are using a standard household outlet rated at 120 volts AC and 10 amps. If you are using a faster charger or a higher voltage outlet, the charging time will be reduced.

It is imperative to note that you should not overcharge your motorcycle battery, as this can damage the battery and shorten its lifespan. When the battery is fully charged, disconnect the charger and do not leave it connected for more than a few hours.

Factors affecting the charging time of a motorcycle battery

1. The type of charger used

There are many types of chargers, from the basic USB charger to more sophisticated models like the trickle charger that can work with different types of devices. The most significant factor to consider when choosing a charger is compatibility. Make sure that the charger you choose is compatible with your device.

The USB charger is the most universal and will work with most devices. It will take longer to charge your device, but it is a reasonable option if you are not sure what kind of charger to get.

On the other hand, trickle chargers are attached to your battery and plugged into a wall outlet. They work by slowly adding charge to your battery over time, so they are ideal for long-term storage. The charger will keep drawing power from the outlet to recharge it until you start up your bike again. This means that you will need to keep an eye on the charger and make sure that it is unplugged when you are ready to ride. You can also charge a battery without a charger using a jumper cable, an Ac adapter, or with cigarette lighter outlet.

2. The voltage of the outlet

As you know the voltage of an outlet in your home or garage is 110 volts while that in Europe is 240 volts. The higher the voltage, the faster the charge. Moreover, when you are using a 220-volt outlet, the charge will be twice as fast as when using a 110-volt outlet. People usually charge their motorcycle batteries at home, so the voltage of the outlet is an influential factor.

3. The type of battery

There are two types of motorcycle batteries, lead acid, and lithium-ion. Lead acid is the most common type and it usually takes about 6 to 8 hours to charge. They require regular maintenance, such as adding water to the cells. The fluid in the battery will evaporate over time, so you need to check the level and add water when necessary.

On the other hand, Lithium-ion batteries are becoming more popular because they are lighter and do not require maintenance. They can be charged much faster than lead acid batteries, in about 4 to 5 hours.

4. The amp-hour rating of the battery

The amp-hour rating is a measure of how much charge the battery can hold. The higher the amp-hour rating, the longer the battery will last. Most batteries have an amp-hour rating of 20 to 30. However, some batteries have a much greater amp-hour rating, which means they will last for more time. You should choose a battery with a higher amp-hour rating if you need the battery to work for a long time.

5. Battery Condition and Age

The age and quality of the battery are other factors that affect how long it takes to charge. A battery that has recently been maintained will charge more quickly than one that has been neglected for a while. Even using the batteries from your motorcycle, you may observe. The time it takes to charge will gradually lengthen as the years go by. The battery first charges more quickly and in less time when it is new. The charging time lengthens as the device becomes older. Now, it takes a long time for the battery to fully charge.

Relationships Between Charging Time And Charging Current

Charging Time And Charging Current Relationship:

Two factors — battery capacity and charging current — affect how long it takes to charge a battery.

The best description of the relationship is:

Battery capacity divided by charging current equals the battery’s charging time.

Each unit’s equivalent units are as follows:

Time spent charging in Hours (Hrs)

Battery capacity is expressed as the battery’s amp-hour capacity (Ah)

Amperes used to express charging current (A)

Optimal Charging Period:

Let’s use an example to determine how long it takes to charge a battery.

The battery has a capacity of 14 Ah ampere-hours. Additionally, let there be a 2 amp charging rate.

So, the charging time is 14 Ah / 2 A, which equals 7 hours.

The battery will be fully charged by the charger in 7 hours. However, this is a best-case scenario in which we assume there won’t be any losses.

Actual Charging Period:

When losses are taken into account, it typically takes significantly longer to charge fully.

Not to mention that the battery will self-discharge throughout the entire time.

The hours needed to fully charge the battery will be longer if we take into account the losses that occur throughout the charging process.

Assuming that during charging the battery, losses happen at a rate of 40%, the charging time is computed as follows.

Charging Time equals to = 14 * 1.4 / 2 = 9.8 Hrs= 10Hrs

As you can see, charging losses lead to a longer time needed to fully charge your battery.

How often should I charge my motorcycle battery?

It is generally recommended to charge your motorcycle battery once every month or so. However, if you ride your motorcycle frequently, you may need to charge it more often.

When should you replace your motorcycle battery?

Your motorcycle battery will typically need to be replaced every two to three years, depending on how often you ride and the type of battery you have. If you ride regularly, you may need to replace your battery more often.

Batteries can lose their charge faster in hot weather, so it’s important to check your battery regularly during the summer months. If your battery is more than three years old, it’s a good idea to have it checked by a professional to see if it needs to be replaced.

Can I replace my motorcycle battery by myself?

Yes, you can replace your motorcycle battery yourself. However, it is critical to read the instructions carefully and make sure that you have the necessary tools before attempting to do so. Furthermore, it is always a smart idea to take your motorcycle to a mechanic to have the battery replaced. This is because you are not confident in your ability to do so.

How long to charge a motorcycle battery by riding?

There is no set time to charge a motorcycle battery by riding, as it depends on how discharged the battery is and the size of the battery. However, generally, it will take a few hours of riding to charge a motorcycle battery. If the battery is completely discharged, it may take longer to charge. To maximize the charging, ride at higher speeds and use the headlight and other electrical accessories.

Can Your motorcycle run without a battery?

No, a motorcycle cannot run without a battery. The battery is needed to provide power to the starter motor, which starts the engine. Additionally, the battery powers the lights and other electrical accessories. without a battery, a motorcycle will not be able to start or run.

Final Verdict:

The motorcycle battery is an integral part of the motorcycle. It will pass away before it’s time if you don’t take care of it. How frequently you ride your motorcycle, how you store it, and whether you have a parasitic draw. These. 

These are just a few of the variables that might determine how long your motorcycle battery lasts. Regularly charging your motorbike battery using a battery tender and keeping it in a cool, dry location will help it last longer.
