We set out to build a smarter charger, and the result is the ingenious microprocessor-based design of our new on-board units. By monitoring factors like temperature and state of charge, they deliver a faster, more regulated precise charge-so you can stay on the water longer, without worrying about your batteries. Our new on-board chargers feature Multi-Stage Charging and Automatic Temperature Compensation for more precise charges that won"t damage your battery. And its automatic shut-off feature extends battery life by shutting down when charging is complete. So your battery-and your day on the water-will always last longer. In high temperatures, our new on-board chargers juice up your batteries up to twice as fast. Thanks to a digital design that monitors everything from temperature to state of charge, our new on-boards get the job done. Comprehensive reading on our new chargers inform you of the charge stage, maintenance mode status, any error notifications and full charge.
