Battery for Harley Davidson – Buying Guide

Buying things without knowing details about them can be a disaster. You have to know exactly what you are paying for, what those labels and marks mean, and why the prices are different. You would love to know that we have prepared this buying guide so that you can have complete knowledge about Harley batteries. Whether you are buying today or planning for a backup or just roaming around no one can stop you to become a Harley battery expert after you have read this.

We will start with the basic types of Harley batteries and explaining their feature, then we will get to know who makes these batteries and will try to describe some of the popular brands, the price ranges available for you to choose from, and we will end with how you will know that your battery has aged enough to consider replacing it with a new one. So, let’s get started.

Battery Types for Harley

Battery Technology is continuously evolving and bringing new features to hold charges and supply electricity when needed. Below some of the Starter Battery types are discussed to give you a clear idea about different types of Harley batteries.

Flooded Lead Acid Battery

This is the most common type of rechargeable battery used to start the engine. The liquid electrolyte is flooded and free to move in the cell compartment. Distilled water can be added to each cell as the battery dries out when discharging. These are heavy and cannot be mounted at any angle because the liquid can be easily spilled. Requires a full charge when stored. It can undertake any weather condition. Requires regular maintenance.

Absorbent Glass Mat (AGM)

This is a sealed Lead-Acid battery in which the electrolytes (acid) between battery plates suspend in a specially designed glass mat. This very fine fiberglass mat absorbs the sulfuric acid and makes this battery spill-proof.

This has several advantages like fast charging and instant high load current on-demand and offers a relatively long service life. This can be mounted at any angle. It charges faster than the flooded type. Best bettery for Harley Davidson available in the market.

This is the preferred battery type for upscale motorcycles that makes it the best suit for a bike like Harley. But this is very much sensitive to overcharging so caution should be taken here and it also doesn’t like the heat of the engine. You can know more details from here.

Gel Batteries

This is also a sealed battery but different in a sense from AGM because AGM is still considered a wet cell battery. It contains a silica type gel that suspends the electrolyte in a paste. This has a recharge voltage lower than other types of lead-acid battery. Gel batteries are very sensitive to overcharging. Can be hazardous when inner materials are exposed to the environment.

Lithium-Ion battery

These are the most expensive type of batteries available. These are continuously evolving with modern technologies. These are of smaller size, charge faster, and have greater longevity compared to others.

Battery for Harley Davidson – Key features

Cold Cranking Amperes (CCA)

Usual starter (cranking) batteries have a CCA value. It is a measurement of the number of amps (current) a battery can deliver when the temperature drops. CCA rating is measured at 0oF. Without enough amp power the motorbike won’t start especially in cold weather.

Battery Size and Motor Compatibility

Powerful engines need powerful batteries. Batteries need to be compatible with the engine power. So, the best batteries for Harley Davidson are going to be bigger and more powerful than the bikes that don’t need that much starting power. For instance Harley sportster battery soze is so big that it’s size is known as XL. You can ensure the right aftermarket battery size for Harley by measuring the built-in battery dimensions.

Battery Capacity

This is one of the important terms to understand because you will see that though the battery has the exact voltage required, you are not quite getting the power you need.

In motorcycle batteries, it is measured in ampere-hours (Ah) and it shows the batteries discharging characteristic. Suppose a battery label says that its capacity is 10Ah which means at fully charged the battery will supply 1 A current for 10 hours.

Voltage

Again, to get the best battery for Harley Davidson it has to be the right voltage battery. Lower voltage will cause failure to certain operations. It is a good practice to check the voltage labeled in the original battery. Most of the Harley battery voltage is 12V.

Recharge Amount

Recharge time depends on the type of battery you are purchasing. Old-school Lead-Acid batteries take more time to recharge than AGM or Gel. Sealed models can handle a limited recharge cycle because they are maintenance-free. The recharge time of a particular model should be checked before buying.

Durability

Best Harley battery should be durable and it may be expressed as Vibrant- Resistant factor. It indicates how likely it is to lose connectivity when exposed to a certain amount of vibration. Manufacturers try to make their batteries as durable as possible. It is one of the important Harley Davidson battery specifications.

Harley Battery terminals

Battery terminals will be used to connect the battery with the electrical cables. Below are some of the most used and popular battery terminals for Harley available.

Lead Battery Terminals

Compatible with best Harley batteries because it is made to meet heavy electrical demand. Provides easy attachments and the same terminal will work for either positive or negative battery post. These terminals are versatile and are the most used terminals in any mechanic shop.

Now, this lead terminal can be coated with stainless steel, to prevent corrosion. The terminals can use a screw to attach with the cable, then it will be a screw terminal, not that much used.

Copper Battery terminals

An excellent choice for the high current electrical system. Provides a high electrical conductivity. Also provides high strengths.

Brass Battery terminals

These types of terminals are recommended to use in a corrosive type environment.
