NOCO GENIUS1 Genius® 1™ 1-Amp Battery Charger Genius^® 1™ 1-Amp Battery Charger – Each

The GENIUS1 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 1-amp for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries
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 GENIUS1 uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging
Its onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor
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
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 and avoids over-charging in hot weather up to 104 F
Automatically detects sulfation/acid stratification
Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting the accessory to battery
Designed to fit battery terminals of any shape and size
Engineered for improved clamping range, clamping force, and higher conductivity
