Now that we have gone over a list of the top selling Harley batteries currently on the market, let’s delve deeper into all of the things that set them apart from each other. While all of the batteries in our buying guide are among the best available, they each have different features that set them apart.
In the buying guide section of this article we are going to explore the answers to the questions of why the right Harley battery is important as well as what features you should consider when shopping for the best battery for your Harley bike.
Why Buying the Right Harley Battery is So Important
When it comes time to replace your battery, you will probably know because your bike either will not start or it takes a long time to start. So now you have to replace the battery, should you just go for the cheapest one? If you are wondering whether or not the brand and type of replacement battery is important, you should consider the following things.
Price and Warranties
One thing that you definitely want to keep in mind when shopping for a replacement battery is whether or not there is a return policy or warranty included with the battery. Even the best battery manufacturers can occasionally have errors. If the battery is not covered by a warranty and it dies in the first few months you may be out of luck, whereas if you have a warranty you are protected by the manufacturer and will be issued a new battery to replace a faulty one.
If the right kind of replacement battery is not selected it may be more difficult or even impossible to install it. One way to check if the battery is right for your bicycle beyond just looking at what models it works with is to look at the actual dimensions of the battery and compare it to the one currently in your bike. If it is a little bit too big or too small you may be able to make adjustments and use that battery, but you will want to take the time and work of installation into your decision when it comes to picking out the right Harley battery.
The right battery will not only get your motorcycle running again, but also improve the performance. A good battery can do wonders for your Harley’s performance. If you are hoping to get a little more power from your Harley in addition to a quicker start-up you can find performance boosting batteries on the market for affordable prices.
If the wrong kind of battery is used it could cause a safety issue. Overheating is one common issue with low-quality car and motorcycle batteries. Acid leaks and corrosion can also be dangerous if they damage the inner workings of the motor. To keep your bike safely on the road you want to ensure that you are using the best battery for your bike possible.
Getting the best performance out of your Harley’s battery can come down to choosing the right one for your bike. If the installation is done correctly and the model of battery matches your bike, you can expect to get many years of use out of it. Paying attention to the warranty options is a good way to make sure that you get the maximum life out of your battery.
Features to Consider When Shopping For the Best Harley Battery
When shopping for a replacement battery for a Harley Davidson you may not know where to begin. There are a variety of high-quality manufacturers of replacement batteries, and there are also cheap knock-offs of the best selling products that you want to keep an eye out for to avoid. In this section of the buying guide we will go into detail about each of the features that we think are the most important to consider when shopping for the best Harley battery.
One of the first things you may want to think about is how much you plan on spending. While there are some decent batteries available for under $100, you are sacrificing performance and technology by not going with a higher quality battery. You can generally expect to spend between $100 and $300 on a new replacement motorcycle battery.
Here are a few of the things that will affect the price:
- Brand — purchasing a battery from a reputable brand with a good track record of producing high performance batteries is always a good idea. You should avoid cheap knock-offs of the top brands because these knock-off products are made with cheap materials that will not last and could even be unsafe. It is better to pay a premium price for a safe and high-performance battery.
- Life Expectancy — if the motorcycle battery is only made to last a couple of years you can expect to pay a lower price. If you want to get the maximum life expectancy out of one battery you can expect to pay more for a higher capacity model.
- What Type of Battery — different types of batteries are more or less expensive than one another for various reasons. Traditional acid batteries are still commonly used, but they are not as good as Lithium or AGM batteries. You can expect to pay up to twice as much for a Lithium battery over an acid battery because they last longer and they won’t leak acid.
Type of Battery
So we know that the battery type will affect the price of the battery, but what are the different types? In this section of the buying guide we will look at the different types of motorcycle batteries and what the pros and cons are of each one. The main difference in the types of batteries comes down to how they perform, how long they last, and what kind of maintenance they require.
Almost all of the batteries included in our buying guide are considered AMG batteries, or Absorbed Mat Gas, which is a unique type of battery that is not the same as a lead acid battery or a lithium battery. It uses acid, but only just enough to create a charge. These types of batteries don’t leak acid like the old lead-acid batteries and they also last a lot longer.
1. Lead-Acid Battery
- Less expensive
- Works in all temperatures
- Easy to find parts and chargers
- Can leak and corrode
2. Lithium Battery
- Better performance
- Cranks up faster
- Usually comes with better warranties
- May need to be “warmed up” first
- Is more expensive
- Requires a special charger
3. AMG Battery
- Lighter than acid batteries
- Does not overheat
- Improves performance
- Holds charge longest
- Lasts longer than acid batteries
- AMG batteries are more expensive
- Overcharging can kill it quickly
Depending on what your goals are for your motorcycle you may prefer either a battery that is equally as powerful or more powerful than the original. The power held by the battery needs to be powerful enough to quickly start up your bike and keep it running effectively. A more powerful battery is preferable, but because the price will go up with the more power you may also want to stick to a battery that has the same performance as the original if you were happy with that performance.
- What does the CCA number mean for batteries?
One acronym that you will come across often while shopping for motorcycle batteries is “CCA” which stands for Cold Cranking Amps. This number is meant to represent how the battery performs when starting a vehicle in cold weather.
The higher the CCA number is, the more power the battery has for starting up in cold conditions. If you live in a colder area you will want to pay even more attention to this number because it will affect you more.
Spill Proof/Leak Proof
Depending on what kind of battery you prefer for your vehicle, it may contain acid or other liquids. AMG type Harley batteries contain the minimum amount of acid which makes them lighter as well as safer to use compared to the old school lead-acid batteries. One of the common problems that occurs with lead batteries is the leakage of acid. If there is a leak of battery acid it can eat through and corrode many parts of your system.
When you are shopping for the best Harley bike battery you want to look for the words
“leak-proof” and “spill-proof”. If the battery is completely sealed then there is no chance for a battery acid leak. Corrosion within the engine and around the battery in your Harley will be terrible for performance, so make sure that the battery that you choose has been tested for quality and performance.
The installation process for the battery is very important to consider. If you are unsure what the installation process entails for a particular battery you may be able to find guides online via the manufacturer’s website or even video references on online streaming platforms such as youtube. Making sure that the battery is the right model and fit for your Harley will make the installation process simpler.
If you want a battery that has more power than the original you may be dealing with a battery that is slightly larger than the original as well. In some cases you are able to install a bigger battery by adjusting the bolts and making other accommodations. Another thing to consider is whether or not the battery comes ready for installation or if it requires you to charge it up first. Having it delivered fully charged will save you some time.
Absorption of Vibrations
When driving down the road, particularly on a motorcycle such as a Harley, there is going to be a lot of vibrations going on within the system. A good battery will need to be highly resistant to these vibrations to keep it performing optimally. While a heavier battery is usually better at absorption of vibrations from the road, there are also some lightweight batteries that have been fortified with special materials to make them more resistant to the effects of vibrations.
When shopping for the best Harley battery one feature that we can not recommend considering the most is the warranty. Newer lithium and AGM batteries have better warranties in general than the older acid-leak models because the manufacturers know that the batteries will last for a long time. A good warranty can pay for itself many times over again in terms of parts and replacements, which is why you should always check with customer service to see what warranty options are available to you when purchasing a motorcycle battery or any other expensive purchase.
Here are some answers to the most frequently asked questions about Harley batteries.
Does the same type of battery work in all Harley Davidson motorcycles?
While it is true that the best-selling replacement models for Harleys usually fit almost all of the models between the 1990’s and present day, there are going to be some exceptions. The size and performance of replacement batteries can vary, and just because a battery works perfect for one bike does not mean that it will have the same performance in every vehicle. You want to make sure that the battery that you choose is the best one for your make and model.
What is the best kind of motorcycle battery for a Harley Davidson?
If you want to know what kind of motorcycle battery is best for your Harley, you want to take into consideration how much money you want to spend, what kind of power/performance you are expecting, as well as what kind of climate you live in. For colder climates a Lithium battery may take too long to start up for you. AGM batteries are a popular alternative to lead-acid batteries that are long-lasting and high-performance.
In conclusion, the MX30L – MOTORCYCLE BATTERY is our pick for the best overall replacement battery for Harley’s because it has consistently been reported to actually improve the power and performance of the bike beyond the capabilities of the original battery, so you not only will fix any battery related problems by using it as a replacement, but you can also notice some differences between the performance before and after.
For a less expensive Harley battery, we recommend the ExpertPower 12v 33ah Rechargeable Deep Cycle Battery [EXP12330]. It is an affordable price, and while it does require recharging, for those who do not use their motorcycles very often this may be the perfect option because you can charge the battery in between sessions without worrying about the battery dying due to not being turned on enough. It is a lower price, so you can expect to get less power than the top model, but it is still high-quality enough to qualify as one of the best Harley batteries for the price.
