As summer is approaching quickly, and temperatures are rising higher and higher, getting out onto the water to enjoy a day of water sports is a great way to enjoy the weather and cool off in the water. Use these tips to help you keep your jet ski battery healthy to avoid having to make an extra stop on the way to the lake for a new battery.
There are several reasons why a jet ski battery will drain and ruin a day full of water sports. Take a look below for the top 5 reasons why your jet ski battery keeps dying.
A jet ski battery should last between 3 - 5 years if properly maintained and cared for. However, this time range is for a healthy battery. If you're not using your jet ski enough and leave the battery in, not properly maintaining your battery in the off-season or not charging it correctly, you may see yourself needing a new battery in as little as one year.
Your jet ski does have a charging system, of sorts. You won't see power steering, windows, locks or remote star. on a jet ski so the electrical demands are much lower. While they do not have an alternator as cars do, they have a stator. A stator will generate enough electricity to maintain the battery charge while you are out enjoying the day on the water but it will not produce enough energy to charge the battery if it is depleted.
A stator is a static component on a jet ski that generates electricity by using electromagnetic coils divided into two groups. One group called an exciter, sends power to the spark plugs to start the engine. The other group, the charging coils, is sent to the battery to provide a small amount of charge to maintain the battery while in use. There is one additional key component powered by the engine that sends energy to the stator to convert it into electricity. That's the flywheel. The flywheel is s spinning metal disc with a heavy metal rim covered in magnets to store rotational energy as the flywheel spins. As the magnets rotate around the stator the mechanical energy is converted into electrical energy.
As a general rule of thumb, if you are not using your jet ski regularly, you should charge your battery once a month to ensure your battery has a long life. Using a smart, automatic charger from X2Power is great for this and for when storing your battery in the off-season to prevent overcharging.
Every jet ski is different but these steps should be followed for all models to avoid damaging the battery.
In the event you have a completely dead battery do NOT attempt to jump-start the battery with your car battery or even a jump pack. This can cause extensive damage to your jet ski's electrical system and is not recommended. If you have a completely dead battery, remove the battery and charge it with an automatic charger as detailed above.
Is your jet ski battery not holding a charge? Bring it into your nearest Batteries Plus and have them tested for free. If they need to be replaced, we have plenty of personal watercraft batteries from Duracell Ultra, X2Power, Xtreme and Odyssey to fit your needs.
