The NOCO Genius Battery Maintainer is a proven piece of equipment to charge and maintain any battery. Most importantly, seasonal batteries. The complaint I hear most about seasonal batteries is that they need to be replaced every year. That is simply not true. With the proper use of a battery maintainer, you can be sure that your battery stays at a full charge during storage. And with the NOCO Genius line of battery maintainers, your battery will never be over-charged and will never sulfate. UltraSafe and Wicked Smart, the NOCO Genius is the one to use because safety and reliability is important.
