It’s an AGM (absorbed glass mat battery) battery, so it is good with high heat and doesn’t suffer the same problems as some other types of batteries that need to be kept upright at all times. It is also an excellent choice for many Harley-Davidson models between 1997-2016 like the Electra Glide, Road Glide, and Road King.

It looks great too. It is really cool that it has the Pirate design on the side, which fits in well with its high-energy, high-output features.

The best part about the Antigravity ATX12-HD-RS Lithium Motorsport Battery is its RE-START function, which reduces the possibility of your bike dying on you or refusing to fire up. With the RE-START function, the battery monitors itself closely, and if it notices a high level of discharge that isn’t normal, it automatically puts itself to sleep. This is a very useful feature because it helps your battery last much longer. When it goes to sleep, it is also very easy to restart your bike as it saves enough energy to do so. All you need to do is press the ‘RE-START’ button, and your battery will be up and running again.
It’s a lithium-ion battery, so it is lighter than most batteries, and it also boasts a long life between charges. It features four terminals at the top and dual polarity.

Best Batteries for Harley Davidson Buying Guide
You might be new to buying the Harley Davidson, and it’s not a choice to be made lightly. You owe it to yourself to be armed with as much knowledge about what you are about to buy-- it’s a commitment. We know that nothing is worse than a motorcycle that just won't run due to a broken or flat battery. Of course, it is important to buy the right battery for the bike first. And this why our buying guide below has been created - to tell you what to look out for when purchasing batteries for a Harley Davidson so that you can prevent breakdown and enjoy the battery in the long term.
What Should I Look out for Before Buying a Harley Davidson Battery?
Picking out the right battery for your Harley is really important. There are a number of batteries out there that can fit the profile, but not just any will do. With this in mind below are a few of the things to look out for when picking out a replacement battery for your Harley Davidson
- Voltage - This is a very important thing to look out for. Most Harleys use 12 volt batteries and naturally not every battery out there matches this. So when next you want to pick out a battery for your Harley Davidson, ensure that you check how many volts the battery is and then you can pick the right battery.
- Recharge Value - One of the most annoying things that can happen to you as a biker is to leave your Harley in the garage with the battery on full charge only to come back in and find that the battery is flat and won’t fire. This is why it is in your best interest to check the brand you’re buying and see what both the manufacturers and people are saying about how well it recharges and how well it holds a charge. The Antigravity ATX12-HD-RS Lithium Motorsport Battery is a good shout as it has a RE-START feature, slows down discharge and is rechargeable.
- Engine Compatibility - This is important as if you get it wrong, you could be stuck with a dud. Different batteries are suitable for different Harleys. For instance, the ThrottleX HDX30L is an ideal battery for Harley Davidson models between 1997-2016 like the Road King. It would be inadvisable to buy this for a Harley under the Street series class. Always check the information that comes with the battery to see what sort of Harley Davidson bike it fits the most.
- Size - Size does matter. If you buy a bigger battery that doesn’t fit into the battery compartment you might find yourself resorting to others means to fit it in and in that case, you could damage the battery. Look into the size of the battery you want to buy and make sure it’s the right fit for your Harley.
- Lifespan/Durability - This doesn’t just apply to Harley batteries, they apply to everything. If you buy a battery that only lasts you six months, that’s just a bad investment. So, read up on the type of battery you’re getting and perhaps look at some reviews so you are well-informed before purchasing one.
What Are the Different Times of Harley Davidson Batteries?
- AGM Batteries - These are very common in the market nowadays. They are factory sealed batteries that require no maintenance. They have good vibration resistance and don’t need to be kept upright as their sealing means they don’t spill.
- Lead Acid Batteries - These are a little old school and need to be kept upright so as to avoid spillages. They consist of lead and lead dioxide and they, therefore, require distilled water.
- Gel Batteries - These are usually used in adverse weather conditions. They are also immune to spillage and corrosion. They pack a lot of power and discharge pretty slowly.
What Are the Best Harley Davidson Battery Brands?
There are quite a number of these, but some of the best include:
- ThrottleX - ThrottleX batteries are made to last. Rugged, Durable and Dependable, ThrottleX batteries are a great replacement battery for your Harley Davidson.
- Yuasa - Yuasa batteries are well respected within the community, with impressive CCA ratings for most of them, and with different sizes, they fit into most Harley classes and models.
- Powerstar - These lines of batteries are high-performance batteries that hold charges longer than most batteries. They also withstand vibrations pretty well, so you hardly ever experience shorts.
- Power Source - These are a set of batteries that are really quick to charge. They also have great CCA ratings. They are AGM batteries that come pre-sealed and require no maintenance.
What Are the Different Types of Harley Battery Terminals Available?
- Lead Terminal - These are the most common type pf battery terminals, and for a while, they were the only ones available. Lead terminals are horizontal in nature and electrically solid
- Steel Terminal - These ones are more robust, and it is highly unlikely that they snap off. They are versatile as they can come with a vertical or horizontal orientation.
- Screw Terminals - These aren’t as common, and they are internally threaded. The nature of these types of terminals means that you can screw directly into the battery. They are easy to deal with and convenient to use.
