There are many different motorcycles and nearly as many types of batteries. Since different bikes will have different levels of power draw, you will find no single ideal battery type for every one of them.

For example, you will find that a dirt bike and a cruiser will use different batteries, as well as many other different components from each other.

Motorcycles of different types can be as different from each other as they are from entirely different kinds of vehicles. We would argue that a dirt bike has more in common with an ATV than it does with a racing motorcycle that is typically only used in high-tolerance competitions on designated tracks.

While different motorcycles will affect what kind of battery you choose to invest in, you will find that it makes little to no difference in the long run, as you will need a battery regardless. There are many different reasons why you would want to purchase a battery for your motorbike.

For example, perhaps your original battery died out, and you just need a replacement that is equally powerful. On the other hand, maybe you want to improve the performance of the battery on your bike so that you can start it up faster and power more electronics on the user interface.

Over the course of our article today, we are going to be taking a look at one of our favorite motorcycle batteries: replacements for Harleys. While the battery doesn’t usually see that much wear and tear on one of those bikes, you will always have to deal with malfunctions and other issues.


When deciding on the ideal motorbike battery, you will want to take a look at the price before making your purchase. A more affordable battery may be the better choice in the short-term, but you may end up finding out that it is less than optimal and it is dying sooner than it should.

We would recommend a battery that is reasonably priced and features excellent build quality to help ensure that there are few issues with longevity and reliability. Since long-term effectiveness is typically an issue with bike batteries, spending a little more up-front has been shown to help.

Of course, the amount that you spend on your bike battery depends on how much you care about it. If you are an avid motorcycle enthusiast, a new battery will be more important to you than it would be to someone else. At the very least, you want to ensure that you are getting reasonable prices.

If you don’t want to end up overspending, we would recommend going over the options that are currently available and then opting for the most cost-effective choice. Doing a decent amount of research will also help ensure that you get the right product for the right price.
