BOATING/FISHING: Never Get Stranded

FOR IMMEDIATE RELEASE

Why Switch to a Marine Lithium Starting Battery?

Norsk Lithium^® meets and exceeds outboard manufacturer specs, provide unparalleled power and features 

New Hope, Minn. (July 8, 2025) – Norsk Lithium^® is proud to offer a line of lithium marine starting batteries that exceeds most outboard manufacturer specs and will never leave you dead in the water; featuring three sets of terminals and included hardware for flexible rigging, Bluetooth^® battery monitoring via the Norsk Guardian^® App, Emergency Start Reserve (ESR), Thermal Core Heating Technology™, and Deep Sleep™ Technologies

“Serious anglers have been waiting to switch to the right lithium starting battery,” said Norsk Director of Product Development/Customer Experience, Jakob Hals.

“And we’ve been working on a solution to meet their needs day and night for the past three years. But we didn’t just want to meet outboard manufacturer specs; we wanted to exceed them while providing a completely unprecedented feature set that provides everything an angler or boater could want – from installation in bass boats to walleye boats to inshore rigs, you name it – anywhere you’ve got a big motor that needs lots of clean, reliable power.”

Norsk Lithium Marine Starting Batteries have been painstakingly evaluated and found to meet, and in most cases—significantly exceed—all performance requirements for lithium starting batteries outlined in the Mercury Marine Performance Bulletin 2022-19R1 released November 2022.

DEAD ON THE WATER: A THING OF THE PAST

First, let’s start with the new marine starting batteries’ most important feature – and that’s something called Emergency Start Reserve (ESR), which allocates 25% of the battery’s capacity as a reserve available on demand.

Say goodbye to emergency jump start packs. With Norsk Lithium you’ll always have the power you need to start your outboard motor at the end of a long day on the water. ESR can be activated with the push of the Power Management Button on the top of the battery or via the Norsk Guardian App. It’s like having a jump start pack built right into your starting battery!

• ESR Included on All Norsk Lithium Starting Batteries
• Locks 25% of the Battery’s Capacity in Reserve by Default
• Access ESR from the Power Management Button on top of the battery case or via the Norsk Guardian App

UNPRECEDENTED NORSK LITHIUM FEATURES & TECHNOLOGIES

“When you compare our lithium marine starting batteries to the competition you’ll find a laundry list of features the others just don’t offer,” said Hals.

“Consider that the vast majority of marine lithium batteries on the market come out of a very small number of factories that offer the exact same battery to a large percentage of companies in the lithium battery space. The only difference is the label on the case. We have partnered with a major consumer electronics provider that takes us out of this manufacturing system. In doing so, we’re able to offer customers never-before-seen technologies and feature sets.

Some of Those Features?

Deep Sleep Technology

One of the most maddening, frustrating and time-consuming problems any boat owner can ever be forced to deal with is having to track down a passive or phantom draw that slowly and painfully sucks the energy out of boat batteries.

Sometimes these low amp draws point back to faulty wiring that needs to be painstakingly tracked down and rewired. At other times, the source of the problem is the boat owner themselves. Ever accidentally left a radio or light on in your boat? Or perhaps you’ve forgotten to turn off all the master power switches? Yeah, we’ve done that more times than we care to admit and our oversight typically resulted in a boatload of dead batteries which is why we knew we needed to come up with a fix that would address the problem and provide an “easy button” solution.

“Enter our Deep Sleep concept, where we can use the BMS brain that sits on top of the battery to make it really easy for users to shut down every battery in their boat through the Norsk Guardian app with the simple touch of a button,” said Hals.

“Press the button, and all the batteries go into Deep Sleep, stopping current from hitting the battery terminals. This also makes sure that if your boat has any parasitic voltage draws that your batteries aren’t going to drain when docked, in the parking lot, or long-term storage,” offered Hals.

“And instead of having to crawl through your compartments and flip switches—we typically remember the master switches immediately after the cover is safely and securely on the boat—you can stand by the side of your boat looking like the smartest guy at the launch, hit one button in the Norsk Guardian app, and all the batteries disconnect power to the terminals in an instant. Same thing for waking them back up when you’re ready to hit the water. Just open the Norsk Guardian app and tap a button. That’s just another example of how we’ve made our new batteries more efficient and user-friendly.”

Norsk Lithium has gone yet another step further by building in a Power Management Button right into the top of each battery.

All Norsk Lithium marine batteries have a built-in State of Charge (SOC) battery meter built into the top of the battery case that provides an SOC read-out with a quick push of the battery management button. This feature provides a quick visual check of the battery’s status without the need for the App on your phone. That same battery management button will also give you the opportunity to wake up the battery from Deep Sleep. A simple tap of the button and your battery wakes from Deep Sleep and you’re ready to roll.

Thermal Core Heating Technology™

“All of our new starting batteries are heated because we recognize that there are numerous situations like early- and late-season tournaments or fishing trips where starting batteries must charge off the alternator below 32 degrees,” said Hals.

“While most companies just hope their batteries will never be used in these extreme situations and make sketchy promises, we use thermally-conductive potted material to ensure uniform and consistent heating for charging in sub-zero conditions,” offered Hals.

Voltage Transient Suppression

Consider Norsk Lithium’s Voltage Transient Suppression (VTS) technology, which is an integrated safety feature that is designed to protect the outboard’s charging system, as well as any devices connected to the starting battery such as pumps, lights, sonar units, shallow water anchors, downriggers, etc. from a voltage spike that occurs in the highly unlikely event the battery’s BMS disconnects the cells while receiving a charge from the alternator.

“We like to think of VTS as the safety feature we hope you never need, kind of like an emergency brake or an airbag in a motor vehicle,” says Hals. “I’ve never had an airbag deployed in any of the vehicles I’ve owned. That said, I’m not going to buy a car without one. The same thought process should apply to your choice for starting batteries” he concluded.

What Voltage Transient Suppression does is significantly suppress the voltage spike that can occur if a BMS in a lithium marine starting battery disconnects, potentially allowing excess voltage from the outboard alternator from damaging the outboard’s charging system and or anything connected to it. Testing Norsk’s VTS system has shown the ability to keep the voltage transient that occurs during BMS disconnect of cells when the alternator is delivering a hefty 30A current to the battery below 17 volts. Without VTS, the voltage measured is often well in excess of 30V which is high enough to damage connected accessories or even the outboard charging system.

“We have a fantastic BMS design but things can happen. As insurance, we’ve built in the technology others don’t offer to prevent any damage from occurring in the event of a BMS failure. And the best part is this protection is built right into the battery and doesn’t require any additional wiring or external hardware,” offers Hals.
