12V 100Ah Heated Dual Purpose Lithium Battery

12100DPH-G24

The Millertech 12V 100AH Heated Dual Purpose Starting Battery delivers reliable cold-weather performance with built-in smart heating technology. When connected to a charger and the internal temperature drops to 32°F, the heater automatically activates, raising the temperature to 34°F before resuming charging. This ensures dependable starts and steady power in frigid conditions. Rugged, marine-grade construction resists vibration and splash, while Bluetooth monitoring provides real-time status. Backed by a 10-year full warranty, it’s a powerful, maintenance-free solution for anglers and boaters who demand performance year-round.
