Norsk Lithium 12V 180Ah Heated Lithium Marine Cranking Battery

The Norsk Lithium 12V 180Ah Heated Lithium Marine Cranking Battery is the highest-capacity cranking battery in the Norsk lineup, built for reliable engine starting in all conditions including cold weather. The built-in Thermal Core Heating Technology allows the battery to charge in freezing temperatures, and the Emergency Start Reserve (ESR) feature, accessible through the Norsk Guardian app, reserves power specifically for engine starting so you can always get home. Triple terminals make rigging straightforward and give you flexible connection options for your specific setup.

Warranty: 10 years standard, extendable to 12 years with Norsk Guardian app registration.

What It Does on the Water

At 180Ah, this is the largest cranking battery Norsk makes. It gives you maximum reserve capacity for large engines, extended accessory loads, or boats that spend long days on the water without access to shore power. The Thermal Core Heating Technology allows the battery to accept a charge even when temperatures drop below freezing. The ESR feature reserves a portion of battery capacity specifically for engine starting, so even if the battery is drawn down from running accessories, you still have enough power to start the engine and get home.

Triple terminals give you flexibility in how you wire the battery to your engine and accessories. Bluetooth connectivity pairs with the Norsk Guardian app for full visibility into battery status and health.
