What Type Of Batteries Does Harley Use?

Harley-Davidson motorcycles are renowned for their powerful engines and exceptional performance. 

To ensure these high standards, Harley-Davidson uses specific types of batteries in their motorcycles.

1. AGM Batteries

Harley-Davidson primarily utilizes AGM batteries in their motorcycles. AGM batteries are a type of lead-acid battery that stands out due to their fiberglass mat. 

This mat absorbs the sulfuric acid, making the battery spill-proof. 

These batteries are particularly valued for their long service life, high current, and low internal resistance.

2. Lithium Batteries

In recent years, Harley-Davidson has also started using lithium batteries, particularly for their electric models such as the LiveWire. 

Lithium batteries are lighter, have a higher energy density, and have a longer lifespan compared to their lead-acid counterparts. 

They are also maintenance-free, adding to their appeal.

How Can You Consider the Right Battery For Your Harley?

Choosing the right battery for your Harley Davidson is crucial to ensuring optimal performance and reliability. 

A few key factors to consider are the battery’s power capabilities, size, and life expectancy, as well as the overall quality and reputation of the manufacturer.

1. Power Capabilities

Check the Cold Cranking Amps (CCA) of the battery. This refers to the battery’s ability to start an engine in cold temperatures. 

Typically, a Harley requires a high CCA rating for a smooth start.

2. Size and Fit

The battery should fit snugly within the compartment without any modifications to avoid vibrations which can cause damage.

3. Life Expectancy 

Look for a battery with a long life expectancy and low maintenance requirements, such as AGM batteries that are known to last longer and require less maintenance.

4. Manufacturer Reputation

To ensure quality, opt for well-known manufacturers with a solid reputation for producing reliable motorcycle batteries.

Note

Lastly, always refer to your Harley Davidson’s user manual or consult with a professional mechanic before making a final decision.

This will help to ensure that you choose the right battery that matches your bike’s specific requirements.

How I Replace a Battery On Harley Davidson?

Replacing the battery on a Harley Davidson is not as daunting as it might seem. Here’s a simple step-by-step guide to help you through this task:

1. Gather Your Tools

You’ll need a Phillips screwdriver, a suitable replacement battery, and a pair of gloves for safety.

2. Locate The Battery

On most of the Harley Davidson models, the battery is located under the seat. Remove the seat to expose the battery housing.

3. Disconnect The Battery

Start with the negative terminal (usually black or tagged with “-“) before moving to the positive terminal (usually red or tagged with “+”). Be careful to avoid causing any sparks.

4. Remove the Old Battery

Once you have disconnected the old battery, the battery should be free to lift out of the compartment.

5. Insert the New Battery

Place your new replacement battery in the same orientation as the old one was situated.

6. Reconnect the Battery

This time, start with the positive terminal before moving to the negative one.

7. Re-place The Seat 

Ensure that all the connections are secure before resetting the seat. Once you have ensured, replace the seat to its position.

Note

Remember, be cautious when handling batteries, as they contain harmful acids and can cause serious harm if not handled correctly. 

Always dispose of your old battery properly to minimize environmental impact.
