Why Batteries Go Flat and The Unique Charging System of a Jetski

We’ve all been there, feeling guilty for neglecting our jetskis during the off-season. For those not living in an eternal summer paradise, winterizing your jetski is essential, but one of the first casualties is often the battery. Unlike cars, which use an alternator, jetskis have a stator system to charge the battery. This stator, located near the crankshaft, generates electricity as the engine runs, converting mechanical energy into electrical power to charge the battery and power the jetski’s electrical systems. It's a compact and efficient system perfect for the watery escapades of a jetski, but without regular use, the battery can quickly go flat, leading to potential long-term damage.

Battery Charger vs. Battery Maintainer: Know the Difference

Understanding the difference between a battery charger and a battery maintainer is crucial to keeping your jetski's battery in top condition. A charger does exactly what it sounds like – it charges the battery, usually at a high rate to quickly replenish its power. However, if you leave a charger on for too long, you risk overcharging and damaging the battery.

Enter the battery maintainer, the unsung hero for offseason battery care. Maintainers charge the battery at a slower rate and are designed to be connected for extended periods. They smartly monitor the battery's charge level and provide power only when needed, preventing overcharging and extending the battery’s life.

Solar Charging: Harnessing the Power of the Sun

Solar charging presents an eco-friendly option to keep your jetski's battery charged, with several pros and cons:

• Pros:

  • Eco-Friendly: Solar chargers convert sunlight into electrical energy, reducing carbon footprint.
  • Low Maintenance: Once installed, solar chargers require minimal upkeep.
  • Cost-Effective: After the initial investment, solar charging is virtually free.

• Cons:

  • Weather Dependent: Solar charging efficiency drops on cloudy or rainy days.
  • Initial Cost: The upfront cost of solar panels and charging systems can be high.
  • Space Requirements: You need sufficient space to install solar panels, which can be a challenge in some storage areas.
