Noco Genius
The NOCO Genius GEN charger is an 8 step, fully automatic switch-mode battery charger which automatically determine the condition of your battery before beginning it’s charge cycle. It will only charge when the battery needs it, and will fully maintain your battery when it is in storage or between uses.
These chargers are true multistage, microprocessor controlled chargers that will not overcharge your batteries ever. Also incorporated in these units is the ability to adjust to low voltage input, which could happen if running it off of a generator or a very long extension chord.
