    What you need to know…
    I’ve had NoCo chargers for 6 years now & just added this Genius 1 (1amp) maintainer. This is a maintainer so don’t think it’s going to take a dead battery & charge it up completely, that’s not what it’s designed for.If you’re going to use this on a vehicle in the 80’s or newer you may need to use a disconnect switch to disconnect the battery as 1amp charging isn’t a lot of charge. If using a disconnect switch isn’t what you want to do, you may need to go up to the Genius 2 (2 amp) or even the Genius 5 to fully charge your vehicle as it sits in storage. NOTE: The newer your car is the more parasitic draw it will have just sitting there from all the electronics, which is why one may need to go to the Genius 5. I’ve used it on my 1930’s cars with 6 volt batteries & it works great. Next I’ll give it a go on my Corvette’s AGM battery & see how it does…,
