The All New Genius.

Better Performance.

The NOCO GENIUS1 Next To The Previous NOCO G750.

Multi-Voltage. Multi-Chemistry. Multi-Battery Type.

Do More With One Charger

A multi-functional design that allows you to charge in more ways. Effortlessly charge multiple battery voltages (6-Volt and 12-volt lead-acid and lithium-ion batteries) chemistries (Flooded, gel, maintenance-free and AGM batteries) and types (Starter, deep-cycle, marine, powersport and more).

Powerful, Efficient, and Compact The Next Generations

Compact, yet powerful battery charger. A mix of electrical engineering and industrial design pack a powerful battery charger into a tiny footprint. The GENIUS1 uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging. And its onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

Improved Start Voltage Sensor. All-New Force Mode.

Charge Dead Batteries.

The all-new start-voltage sensor allows the GENIUS to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on force mode to detect and charge batteries all the way down to zero volts.
