Norsk Lithium 12V 120Ah Heated Lithium Marine Cranking Battery

The Norsk Lithium 12V 120Ah Heated Lithium Marine Cranking Battery is 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, gives you a backup power reserve when you need it most. 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

A lithium cranking battery at 120Ah gives you significantly more reserve capacity than a traditional lead acid cranking battery, with less weight. The Thermal Core Heating Technology allows the battery to accept a charge even when temperatures drop below freezing, which matters for early spring and late fall fishing in the Brainerd Lakes area. 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.
