Noco Genius 4A 2-Bank Smart Battery Charger and Maintainer 4204003

The NOCO Genius 4A 2-Bank Smart Battery Charger and Maintainer is one of NOCO's most powerful, highest-performing, energy-efficient, and compact chargers yet.2-bank battery charger, battery maintainer, trickle charger, and battery desulfatorThe perfect all-in-one solution for battery maintenanceBattery charger maintainer rated a 4-amps - 2-amps per bank with a 40Ah capacity rangeDesigned to charge and maintain multiple vehicles like cars, motorcycles, boats, ATVs, RVs, lawnmowers, lawn tractors, trucks, and moreDesigned for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteriesIntegrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-chargingCharge dead batteries - Charges batteries as low as 1-voltAutomatically detects battery sulfation and acid stratification to restore lost battery performanceNot just a trickle charger, it's an advanced battery maintainerFully-automatic, worry-free battery charger for everyday use - 24/7 - with zero overchargeThe NOCO Genius 4A 2-Bank Smart Battery Charger and Maintainer is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator. Each bank is rated at 2-amps for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries. The Charger uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging, and the onboard microcomputer precisely controls the charging to minimise power loss to create an incredibly compact form factor.This Smart Battery Charger / Maintainer has a multi-function design which allows the user to 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). There is also an all-new smart voltage sensor which 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. It is also able to automatically detects sulfation/acid stratification. If any is found, the Charger will automatically repair and reverse the damage done to the battery, extending the usable life and increasing the performance.Inside there is a new integrated thermal sensor which 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. This also helps to avoid under-charging in cold weather down to -4F and avoids over-charging in hot weather up to 104F. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.The Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets
