Nothing beats the thrill of being on the open water. The sun, the spray, and the power of your Yamaha WaveRunner or Kawasaki Jet Ski beneath you make for a perfect day.

Our inventory is packed with top-quality sealed AGM and lithium jet ski batteries. These are built tough to handle the bumpy ride on the water and the big power needed for your jet ski.

Choosing the Right Personal Watercraft Battery for Your Ride

So, how do you pick the right battery? It can seem tricky with so many options. But don’t worry, we are here to make it simple. The most important step is finding a battery that fits your specific watercraft.

Think of it like buying shoes. You need the right size and style for the job. A battery is the same. It has to match your personal watercraft perfectly to work correctly and safely. This is the first and most important step.

Match Your PWC Brand & Model

Finding the correct personal watercraft battery starts with matching it to your ride. We have a huge stock of batteries for all the big PWC brands. This includes top names like Yamaha, Kawasaki, Sea-Doo, Honda, and more. It is very important to match the jet ski battery size and power needs that your machine's maker recommends.

Using the wrong battery can cause a lot of problems. It might not fit in the battery tray, or it could cause electrical issues. For example, the Yamaha VX Cruiser battery might be different from the Kawasaki Jet Ski battery.

To make things easy, you can use our product filters. They help you find the exact replacement battery for your model. You can also search by the original OEM part number printed on your old battery. This means you get a perfect match without any Confusion.

AGM vs. Lithium: Which PWC Battery is Best?

Once you know the right size, it is time to choose the battery type. For personal watercraft, the two best choices are Sealed AGM and Lithium. They are much better than old and conventional wet batteries.

Both AGM and Lithium batteries are designed for powersports. They are built to handle shaking, vibrations, and big power demands. Let’s look at each one so you can decide which PWC battery is right for you.

Sealed AGM Jet Ski Batteries: The All-Around Champion

Sealed AGM batteries are the most popular choice for a reason. AGM stands for Absorbed Glass Mat. This technology makes the battery super tough and reliable. It is the perfect all-around champion for almost any jet ski or wave runner.

The best thing about an AGM jet ski battery is that it is sealed and spill-proof. You never have to worry about adding water or cleaning up acid leaks. This makes them very safe and easy to own. The sealed AGM design is a huge plus for a vehicle that bounces on the water.

These batteries are also amazing at resisting vibration. The constant slapping of waves can damage a normal battery, but an AGM PWC battery is built to take it. They offer fantastic power, a long life, and great durability, all at a fair price. For most riders, an AGM battery is the perfect choice.

Lithium Jet Ski Batteries: For Maximum Performance

If you want the absolute best performance, a lithium jet ski battery is the way to go. Think of it as a premium upgrade for riders who want an edge. These batteries use the latest technology to give you a big boost in power and a huge drop in weight.

The biggest benefit of a lithium battery is how light it is. They can be up to 70% lighter than a traditional battery. Less weight means your watercraft can be a little faster and more nimble. It is an easy way to improve performance.

Lithium batteries also provide stronger and faster starting power. They have a very long lifespan, often lasting years longer than other batteries. While they do cost more upfront, their long life and amazing performance make them a great investment for serious enthusiasts who demand the best.

Understanding Your Jet Ski Battery Specifications

When you look at different batteries, you will see some numbers and letters like CCA and Ah. These are not just for show. They tell you how powerful the battery is. Understanding them helps you choose the best waverunner battery for your needs.

Think of these specs as the battery's report card. They tell you how well it can do its job. A good battery will make sure your PWC starts fast and runs great.

Power & Performance

When you compare models, look at a few key technical details. The first is Cold Cranking Amps (CCA). This number tells you how much power the battery can deliver to start your engine in cold conditions. A higher CCA means more starting power. This is great for firing up a stubborn engine quickly. It also helps you easily start an engine that has been sitting for a while. 

Next is the Amp Hour (Ah) rating. This tells you about the battery's energy storage. Think of it as the size of the fuel tank. A higher Ah means the battery can run electronics for longer when the engine is off. For a personal watercraft, a strong CCA is usually the most important factor.

Finally, you will see the voltage. All of our PWC batteries are the standard 12V jet ski battery format. This means they are fully compatible with your machine's electrical system, so you can plug it in and go. Choosing the right personal watercraft battery means matching these specs to your needs.

How to Care for Your PWC Battery

Getting a great battery is the first step. The next step is taking care of it. A little bit of care can make your battery last much longer. This saves you money and makes sure your watercraft is always ready to go.

Proper care is simple. It just involves keeping the battery clean, charged, and properly stored. If you do these things, your battery for jet ski will give you years of reliable service.

First, always keep your battery terminals clean. Dirt and grime can cause power to leak out. Use a wire brush to gently scrub the terminals if you see any buildup.

Second, make sure the battery stays charged. During the riding season, your PWC's engine will do this for you. But if you do not ride for a few weeks, it is a good idea to check the charge.

The most important time for care is the off-season. When you store your PWC for the winter, do not just forget about the battery. A battery can slowly lose its charge over a few months and die. To prevent this, you should use a smart battery maintainer. A maintainer gives the battery a small, steady charge that keeps it healthy without overcharging it. This is the single best thing you can do to make your personal watercraft batteries last.

Frequently Asked Questions

We get a lot of questions about PWC batteries. Here are answers to some of the most common ones. We hope this helps you feel confident in your choice.

How many volts is a jet ski battery?

Personal watercraft, including all models of Jet Skis and WaveRunners, use a 12-volt battery. It is very important to only use a 12-volt battery. Using the wrong voltage can seriously damage your PWC's computer and electrical parts.

How often should I charge my jet ski battery?

During the season, you should not need to charge it manually if you ride regularly. However, in the off-season or during long storage, you should charge it every 30 to 60 days. The best solution is to connect it to a smart battery maintainer, which will keep it perfectly charged automatically.

How much is a jet ski battery?

The price changes depending on the battery type, brand, and power. Old-style conventional batteries are the cheapest. High-performance sealed AGM and lithium batteries cost more, but they offer much better durability, power, and lifespan.

What is the best battery for a Yamaha WaveRunner?

For most Yamaha WaveRunner battery needs, a high-quality sealed AGM jet ski battery is the best mix of price and performance.
