Smart Battery Charger & Maintainer, 2A, 6V/12V, Automatic Trickle Charger, GENIUS2

The NOCO GENIUS2 is a compact 6V and 12V, 2-amp smart battery charger, maintainer, trickle charger, and desulfator for lead-acid and lithium-ion batteries, including flooded, gel, AGM, SLA, maintenance-free, and LiFePO4. It works with cars, trucks, motorcycles, ATVs, boats, RVs, lawn mowers, classic cars, and more, making it ideal for everyday maintenance or long-term storage. Fully automatic operation is safe for 24/7 use with zero risk of overcharging, and an integrated thermal sensor adjusts the charge to ambient temperature to prevent overcharging in heat and undercharging in cold. It charges batteries from as low as 1 volt, and Force Mode manually revives completely dead batteries down to 0 volts. Multi-voltage, multi-chemistry, and energy-efficient in a tiny footprint.
