What to Look for Before Buying?

If you were to buy a new battery for your Harley Davidson motorcycle without proper knowledge and research, there is a good chance that you would get ripped off. Factors such as motorcycle compatibility, power, voltage, etc., play a huge role in the performance of a battery.

Here are some of the key factors you want to think about when shopping for a motorcycle battery.

1. Physical Dimensions

The first and the most obvious element to check is the physical dimensions of the battery that you are planning to buy. All motorcycles have a pre-designated area where the new battery needs to be installed. If the battery size does not fit the area dimensions properly, you will not be able to install it.

So, before you start looking for batteries, take some time to measure out the size of the battery that is already in your Harley Davidson bike. Then use that measurement to figure out which options available in the market will be the right choice for your motorcycle.

2. Battery Type

As you may have noticed from our list of reviews, two different types of batteries are suitable for your Harley. And you need to understand both of them before you commit to a specific type since each has its share of strengths and weaknesses.

Battery for Harley Davidson
  • SLA/AGM Battery

The term SLA stands for Sealed Lead Acid, while AGM means Absorbed Glass Mat. This type of battery is a variation of the sealed acid type of battery that is standard for automotive. Because of absorbed glass mat separators, these units require less maintenance and are usually spill-proof.

  • Lithium-Ion Battery

Lithium-ion batteries, on the other hand, do not require any acid and are quite lightweight. These batteries are a fantastic investment if you are willing to spare the money. Keep in mind, though, Harley Davidson bikes do not come with lithium-ion batteries, and installing one might require some additional steps.

3. Voltage

Typically motorcycles run on 12 Volt batteries. Very rarely, some motorcycles require a higher voltage battery, but the likelihood of your bike being one of them is very slim. Still, for clarity’s sake, you should take a look at your motorcycle manual to check the battery specifications.

When it comes to voltage, you want to match the voltage of the new battery with the old one. So, if your old battery runs on 12 volts, the new one should be the same.

4. Battery Capacity

Battery for Harley Davidson

Despite being such an important factor when buying a motorcycle battery, the battery capacity often gets overlooked because of how little a casual user might know about it. Every battery you buy should have a battery capacity listed in its product specifications.

Ideally, you want to make sure the new battery has the same battery capacity or more than your old one. Battery capacity is measured in amp-hour/Ah. So if your old battery has a capacity of 18 Ah, for example, the new one should have at least 18 Ah or higher capacity.

5. Cold Cranking Amps

The cold cranking amps, or CCA for short, is the measure of your battery’s performance in dire situations. It is a worst-case performance assessment for the battery. If you are planning on riding your bike on extremely cold days, then this is something you want to check carefully. 

The higher the CCA number of your bike, the better its performance. This number dictates the number of amps your battery can dish out when operating at 0 degrees Fahrenheit for 30 seconds. However, this might not be the most critical thing to check for casual users who do not right their Harley during extreme winter days.

6. Build Quality

If the power and dimensions of the battery match your requirements, the last thing you want to check is its overall build quality. Take a look at its expiration date to get an idea of how long it will last. In addition, carefully check the quality of the connectors and the terminals.

The better the condition of the terminals, the longer it will last. If you are going for an AGM battery, then look at the condition of the seal to determine whether it really is spill-proof. All these elements will help you get a clear picture of the durability of the battery.
