    NOCO FAQ

    What types of batteries can you charge with a NOCO Genius?

    Any type of sealed lead acid battery; including wet (flooded) and gel (gel cell) batteries.

    How do I choose a battery charger?

    First find the Ah Rating on the battery you will be charging. Each battery chargers are rated for a range of batteries (based on Ah). As a general rule of thumb when selecting a charger for a lead acid battery, match the voltage and use one that is no more than 20% of the capacity rating of the battery (at a 20hr. rate).

    Example; to charge a 12 volt / 7.5Ah battery select a charger with a maximum charge output of 1.5 Amps (7.5 x 0.20 = 1.5).
