What is the best Harley battery?

There is no one-size-fits-all answer to this question, as the best Harley battery for your bike depends on a number of factors. However, here are a few things to keep in mind when choosing a battery for your Harley:

  • First, consider the size of your motorcycle. A bigger bike will need a battery with more power and reserve capacity than a smaller one.
  • Second, take into account how you use your motorcycle. If you do a lot of stop-and-go city riding, you'll need a different type of battery than if you mostly take long highway trips.
  • Finally, consult your owner's manual or talk to a qualified Harley mechanic to get specific recommendations for your bike.

How long should Harley battery last?

The battery life can vary so much depending on the make and model of your Harley, how often you ride, and how well you maintain your bike. However, in general, you can expect a Harley battery to last anywhere from two to five years. Of course, if you take good care of your bike and your battery, you can extend its life even further.

Here are a few tips to help you get the most out of your Harley battery:

1. Keep it clean. One of the best ways to prolong the life of your Harley battery is to keep it clean. Make sure to wipe down the terminals and connections with a cloth or brush every few weeks to remove any dirt or buildup. This will help maintain a good connection and prevent corrosion.

2. Store it properly. When you're not riding your Harley, it's important to store the battery properly. If possible, keep it in a cool, dry place out of direct sunlight. This will help prevent the battery from overcharging or discharging too much.

3. Charge it regularly. Even if you don't ride your Harley often, it's still a good idea to charge the battery regularly. This will help keep it in good condition and prevent any unexpected issues.

4. Keep an eye on the level of electrolytes. The level of electrolyte in your battery should be checked regularly to ensure it's at the proper level.

5. Avoid deep discharge cycles. Deep discharge cycles can shorten the life of your Harley battery, so it's best to avoid them if possible. If you do need to discharge the battery completely, make sure to charge it as soon as possible afterward.

Following these simple tips, you can help extend the life of your Harley battery and keep it running strong for years to come.

How many CCA does a Harley need?

The ideal battery for a Harley Davidson motorcycle is one that has at least 300 cold-cranking amps (CCA). This will ensure that your bike has enough power to start on even the coldest days.

Batteries with less than 300 CCA may struggle to start your motorcycle on very cold days (-15°F or lower), so it is best to err on the side of caution and go with a higher CCA rating if possible. In general, batteries with a higher CCA rating will also have a longer lifespan than those with a lower rating.

What type of battery does Harley use?

Harley-Davidson batteries are made with high-quality components and are designed to withstand the vibrations and jolts that come with riding a motorcycle. They're also built to last, so you can count on them to start your bike day after day, mile after mile. 

What volt battery does a Harley-Davidson use?

Most Harley-Davidson motorcycles use a 12-volt battery. However, there are some models that use a 6-volt battery. The type of battery you need depends on the year and model of your Harley.

To find the right battery for your motorcycle, you'll need to know the make, model, and year it was manufactured. You can usually find this information on a sticker or plate located on the frame of your bike. Once you have that information, you can head over to a local Harley-Davidson dealer or an online retailer to find the correct battery for your bike.


Harley Davidson batteries are not just like any other battery. They have to be able to withstand the extra load that comes with a Harley engine. With all of the different types and brands of motorcycle batteries on the market, it can be hard to know which one is right for your bike.

This article has taken some of the guesswork out of it by recommending five of the best Harley Davidson batteries on the market. So, whether you're looking for a replacement battery or just want to be prepared in case of an emergency, try any one of these batteries, and rest assured that your Harley will startup no matter what.
