5-Amp Battery Charger, Maintainer & Desulfator (NOCO GENIUS5)

Introducing the all-new GENIUS5, one of our most powerful, highest-performing, energy-efficient, and compact chargers yet. The GENIUS5 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 5-amps for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

The All-New GENIUS: Smaller Size, More Power

Compared to the previous NOCO G3500 model, the all-new NOCO GENIUS5 delivers better performance while being 34% smaller in size and delivering 65% more power.

Do More With One Charger: Multi-Voltage And Multi-Chemistry

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).

The Next Generation: Powerful, Efficient, And Compact

A compact, yet powerful battery charger. A mix of electrical engineering and industrial design packs a powerful battery charger into a tiny footprint. The GENIUS5 uses high-frequency switch-mode technology to efficiently convert AC power into safe DC power for battery charging. Its onboard microcomputer precisely controls the charging to minimize power loss, creating an incredibly compact form factor.

Charge Dead Batteries: Improved Sensor And All-New Force Mode

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.

Completely Automatic: Year-Round Charging And Zero Overcharge

Finally, a charger from start to finish that’s completely automatic. No special modes, no technical knowledge required. Genius will safely charge any battery. It detects damaged batteries and intuitively repairs them, and actively monitors for long-term battery maintenance to extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.

Thermal Compensation: More Precise Charging In Any Climate

The new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4°F (-20°C) and avoids over-charging in hot weather up to 104°F (40°C).

Bring Batteries Back To Life: Auto Detection And Auto Repair

The GENIUS5 automatically detects sulfation and acid stratification. If any is found, the GENIUS5 will automatically repair and reverse the damage done to the battery, extending its usable life and increasing performance.

Redesigned Clamps: Improved Clamping Range And Force

Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting the accessory to the battery. Designed to fit battery terminals of any shape and size. Engineered for improved clamping range, clamping force, and higher conductivity.

GENIUS5 Charging Times

Approximate charging times are based on a 50% depth of discharge.
