The GENIUS5 is one of NOCO's highest-performing, most energy-efficient & compact chargers yet. The GENIUS5 is a 6V & 12V battery charger, battery maintainer & battery desulfator rated at 5 Amps for lead-acid automotive, marine & deep-cycle batteries, including flooded, gel, AGM & maintenance-free, plus lithium-ion batteries.

The NOCO Genius range is completely automatic. Genius chargers will safely charge any battery with no technical knowledge required. They will detect damaged batteries and intuitively repair them. Beyond just repairing damaged batteries, Genius chargers actively monitor for long-term battery maintenance and help extend battery life. This system allows for continual operation without user intervention and zero risk of overcharging your battery.

Genius uses an integrated thermal sensor to detect the ambient temperature and alter the charge to eliminate over-charging in hot climates & under-charging... in cold climates. They will charges dead batteries as low as 1 Volt, or go manual with the new Force Mode that allows you to begin charging dead batteries down to zero volts.
