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 begin charging dead batteries down to zero volts. Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.Compatible with all types of vehicles.
