DEEP SLEEP™ 
Disconnect power to your battery’s terminals using this feature in the Norsk Guardian® app to eliminate fully-discharged batteries caused by phantom draw – storing your battery has never been easier!
THERMAL CORE HEATING TECHNOLOGY
Our proprietary Thermal Core Heating Technology™ checks the temperature of the cells inside the battery and reroutes the inbound current from the charger to warm the cells if the cell temperature is below 32F. / 0C. Once the internal cell temperature has been increased to a safe charging temperature, the current from the charger is routed to the cells so a safe charge can take place. With the addition of full potting with thermally conductive epoxy, custom heat pads, and our proprietary heating control algorithm, NOBODY does heated batteries better!
BCI-COMPLIANT CASES 
Norsk Lithium 24V Deep Cycle batteries are constructed in BCI-compliant cases, ensuring they fit in the same space as a Group 31 lead-acid or AGM battery. This eliminates the need for an oversized proprietary battery tray.
ONE-TOUCH POWER MANAGEMENT
The Power Management button, found on all Norsk Lithium® marine batteries, allows the user to quickly check State of Charge, and manage advanced features such as ESR and Deep Sleep™ or reset the BMS.
IP67 WATERPROOF
IP67 Waterproof ensures that your Norsk Lithium® Marine Battery is fully protected against dust and capable of withstanding immersion in water up to 1 meter deep for 30 minutes.
