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® 12V Deep Cycle batteries are constructed in BCI-compliant cases, ensuring they fit in the same space as a Group 27 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® Boat Lift 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® Boat Lift Battery is fully protected against dust and capable of withstanding immersion in water up to 1 meter deep for 30 minutes. This high level of protection guarantees that your battery remains operational in the harshest environments, providing reliable performance and durability.

8,500–10,000+ lbs	*Verify Motor Draw — may require multiple batteries or 24V setup	Single 180Ah or Multiple Batteries

LIFT / CURRENT DRAW	RECOMMENDED BATTERY
Up to 2,500 lbs Typical Current Draw 50–75A	Single 12V 105Ah
2,500–6,000 lbs Typical Current Draw 40–85A	Single 12V 120Ah
6,000–8,500 lbs Typical Current Draw 80A+ / *Verify Motor Draw	Single 12V 120Ah or 180Ah
8,500–10,000+ lbs Typical Current Draw *Verify Motor Draw — may require multiple batteries or 24V setup	Single 180Ah or Multiple Batteries

*Electric boat lifts over 6,000 lbs should be verified before final battery selection. Confirm motor draw, system voltage, and startup surge to ensure the battery setup supports the load while staying within the system’s 1C discharge limit. Larger cable lifts may require a 12V 180Ah battery, parallel batteries, dual motors, or a 24V setup.

ELECTRIC LIFT NOTES

Most residential electric lifts perform exceptionally well with a single Norsk Lithium battery.
A 12V 105Ah battery is ideal for smaller lifts and lighter boats.
A 12V 120Ah battery is recommended for larger lifts, heavier boats, longer lift travel, or customers wanting additional reserve capacity.
Solar charging systems are commonly used and pair exceptionally well with lithium batteries.

18,000–30,000+ lbs Hydraulic Demand 150–300A+ / *Verify Motor Draw	Two or More 180Ah Batteries

*Hydraulic boat lifts over 12,000 lbs should be verified before final battery selection. Confirm motor draw, system voltage, and startup surge to ensure the battery setup supports the load while staying within the system’s 1C discharge limit. Larger hydraulic lifts may require parallel batteries, multiple 180Ah batteries, or a 24V setup.

HYDRAULIC LIFT NOTES

Hydraulic lifts create higher startup and operating loads than electric systems.
Battery sizing should account for both continuous current draw and startup surge amperage.
Larger hydraulic systems may require batteries connected in parallel to provide adequate discharge capability and reserve capacity.
Verify actual motor draw before final battery selection.
Battery sizing should account for operating current, startup surge amperage, system voltage, lift manufacturer requirements, and the battery system’s 1C discharge limit.
