NOCO GENIUS1 6V/12V 1-Amp Smart Battery Charger

Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries. An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. Charges dead batteries as low as 1-volt. All-new Force Mode that allows the ability to take control and manually charging of dead batteries down to zero volts. A fully-automatic, worry-free battery charger for year-round use. Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life. Compatible with all types of vehicles.
