As an Amazon Associate, I Earn From Qualifying Purchases.

One of the most important components of the Harley Davidson Motorcycle is its battery. Harley Davidson Motorcycles are expensive, and you want to make sure that the motorcycle lasts as long as possible. The Harley Davidson Battery should be replaced every five years or so, depending on use. If your Harley Davidson Motorcycle starts having trouble starting up, there could be a problem with the battery. It’s time for a new Harley Davidson motorcycle battery.

Here are 13 things you should know about Harley Davidson Motorcycle Battery:

What brand of battery does Harley Davidson use?

Harley Davidson is one of the most popular motorcycle brands, and they’re known for their motorcycles’ characteristically powerful engines. Harley batteries are manufactured by Deka (East Penn Manufacturing), and they are currently the official manufacturer of a majority of the official Harley Davidson motorcycle batteries.

How many CCAs does a Harley battery need?

Your Harley Davidson motorcycle battery will need at least 300 CCA. Motorcycle batteries are different because their higher charging rate makes them more susceptible to heat and discharge. Plus, the increased vibration of motorcycles may increase self-discharge or lead to “dry-cell” or sulfation issues.

The ideal location for a Harley battery is in an insulated, well-ventilated space where it won’t freeze when the temperature drops below 0 degrees Celsius (32 degrees Fahrenheit) but won’t overheat in warmer climates when its temperature exceeds 55 degrees Celsius (131 degrees Fahrenheit).

Most Harley owners recommend using an external battery tender that plugs into your wall outlet during off-season storage to ensure continuous charging without the risk of overcharging.

How long should a battery last in a Harley Davidson?

A Harley-Davidson battery is designed to last for at least five years. But how long your battery lasts depends on many factors, including the driving habits, charging regimen, and maintenance schedule you follow. If you know how to care for your battery so that it lasts as long as possible, it could be around for decades.

How many amps does a Harley Davidson starter draw?

Starters on Harley Davidson motorcycles only need up to 15 amps of current. However, with resistance and heat, it will sometimes draw more. If the starter needs more than 15 amps, there can be certain issues with electronics, or perhaps a lack of lubrication is slowing the motor down enough for sufficient cooling.

If your starter draws more than 15 amps, it can be due to mechanical resistance or heat issues. However, you should also check for electrical problems since this could lead to bigger issues later on if they are not fixed immediately. The best thing you can do is consult with an expert who can inspect your motorcycle and let you know if there is a bigger problem with the electrical system.

How many cold cranking amps does a stock Harley Davidson battery have?

Some companies may use a higher voltage, but the most common voltage is 7.0 volts on a 12-volt battery. When you have a stock late model 96 engine that needs to be cranked, it uses around 145 – 150 amps of power when the engine is cold.

How long should I let my Harley warm up?

Newer Harley motorcycles use a fuel injection system. A fuel injection system is better because it can circulate oil faster and doesn’t need a long time to warm up. But still, we recommend that you let your motorcycle warm-up for at least 1-3 minutes so the oil can coat all engine surfaces.

Can a Harley run without a battery?

Though modern Harleys cannot start without a battery, there are other ways to get them started. For instance, if at least some life is left in your battery, you can push-start your bike. Some older models may also be equipped with kick-starters that can start without needing any outside assistance whatsoever!

How do you start a Harley with a dead battery?

There are a few things that you could try that will get your bike’s engine going again!

Try jump-starting. Check the gaps to make sure they’re clean and closed, and then go over all of the connections to ensure they can touch properly. Clamp one end of the jumper cable’s positive wire to connect it to the positive post at the front side of your battery, and clamp down on its other end (the negative) with an eyeglass screwdriver or something similar.

Clampdown on the negative wire for about 3 seconds with one hand, take off your hold after 1 second has passed, and clamp down on it again for another 2 seconds before shutting off again for another 5 seconds, then let go completely. Do this until your engine starts up.

Try removing the battery and charging it at home through a power outlet or another motorcycle. If you have one available to borrow for an hour, then place it back inside your Harley Davidson before turning on its ignition switch.

If that doesn’t work, try purchasing a new battery from Amazon because this could be what’s wrong with your Harley.

Why won’t my Harley battery hold a charge?

If your Harley battery is not working, it could be because it’s dead. A dead battery is no longer able to hold an electric charge. If you find that your bike doesn’t work, you need to replace the battery with a new one as soon as possible.

On the other hand, if your Harley’s battery is not working, it could be because the alternator isn’t charging. An uncharged battery won’t hold a charge for very long. If you find that your bike doesn’t work, you need to replace the battery with a new one as soon as possible so that you can get back on the road safely and avoid getting stranded.

Finally, if you think that your battery might be dead, consider taking it to an authorized Harley-Davidson dealer right away. It is best not to leave a damaged or dead battery in your bike for longer than necessary because the acid inside of it can cause damage and corrosion on other parts of your motorcycle if left unchecked over time.

What charges the battery on a Harley?

The Harley’s charging system includes three parts: the battery, alternator, and regulator. The battery, which stores energy for the bike and is a buffer to ensure it, has enough power. The alternator, which creates alternating currents to run the bike and charges the battery. And finally, the regulator. It makes sure that you have enough voltage for your bike not to stop running when you are riding it fast or far away from home.

How long do Harley voltage regulators last?

The Harley Voltage Regulator is designed to last for the bike’s life, but eventually, it will need to be replaced.

The Harley Voltage Regulator is a very important mechanism responsible for stabilizing the voltage of your bike’s electrical system.

If this becomes faulty, it can cause any number of problems ranging from reduced power to an engine stall.

The voltage regulator is like a car’s engine. It makes sure that the electricity is okay. If it becomes faulty, then the electricity will become bad.

Usually, this part lasts for a long time, but not forever.

For example, when you are driving your car, and the lights blink off and on – that means something might be wrong with this part of your car’s engine!

What should a Harley charge at?

Harley Davidson motorcycles should charge between 13.2-15 volts to run well. While the engine is running, use a voltmeter to measure the voltage. If it’s 7-13 volts, the motorcycle doesn’t have enough charge and will probably stall under acceleration or while driving up steep hills. If the voltage is below 7 volts, the battery will not have enough power to start the motorcycle.

How does a Harley charge the battery?

The charging system has three parts. One is the battery, which stores electrical energy, and it helps make sure the bike’s batteries are charged. Another part is the alternator (AC), which creates alternating currents to charge your motorcycle battery. Lastly, it would help if you had a regulator or rectifier that changes direct current into alternating current so that your bike runs well.

The Harley-Davidson bikes all share the same type of charge system. It’s rated for a battery capacity of 10A and has a float voltage of 13.5 volts. Still, it also uses a generator regulator charging system to keep it in line with fluctuating voltages without damaging motor components that electrical surges or dips could harm in voltage.

Moreover, the Harleys use an automatic full-time relay that automatically switches from charging to generating power when needed to regulate its output—many like vehicles come equipped with alternators designed to self-regulate their output through complex circuitry.

On the other hand, the Harley charge system works exceptionally well during periods of temperature change, providing enough juice to get you through steep mountains or into places where no one else will go.

Although to provide enough power when you need it most, Harley-Davidson’s four-valve V-Twin engines are built with a low COG (center of gravity) design to help them handle the added weight of the electrical system. This system includes six coils for each cylinder, each one producing 3000 volts to keep the engine running at optimal fuel efficiency under any condition.

This system is very similar to what you would find on higher-end vehicles that use computerized management systems for their power train. Some higher-end vehicles do come with electrical charging systems like Harley. Still, they are considerably more complex due to hybrid technology that features a battery pack and an electric motor.

In the end, Harley’s charging system is simple in design, but it is very effective under most circumstances. While it is not perfect for extreme conditions—for example, its output can be affected by extremely high or low temperatures—in most cases, it works well to provide enough power to get you where you need to go.


If your Harley Davidson motorcycle battery is starting to show signs of age, it may be time for a new one. However, before you start shopping around for the best replacement battery on the market, make sure that you are aware of these 13 things about your bike’s power source. By understanding how to take care of your bike and properly maintain its components, you can ensure that it will work at optimal levels well into the future.
