Built to handle the rough water.

Your lifestyle can be very demanding, especially on your boat or RV battery. From the constant pounding of a trip across the water, to the deep discharge demand required for today’s luxury RVs, you need reliable, superior performance.

NorthStar Marine/RV batteries deliver more starting power and exceptional deep cycling capability of over 900 cycles at 50% depth of discharge, with increased reserve capacity to power all on-board electronics. NorthStar batteries are designed to deliver superior performance, while exceeding conventional battery life expectancies, reducing the overall cost of ownership.

Don’t take any risks by using other batteries – if you need the best, you need a NorthStar Ultra High Performance Pure AGM.

"NorthStar builds the best deep cycle battery I've ever been around."

Mark Menendez has spent the past 17 years on the professional bass fishing circuit. Over his career, he has won more than $1,000,000 in earnings, and his continued success is a testament to his passion for competition and his skill on the water.

Mark knows how important it is to have reliable power supply during competitions. He needs batteries that can deliver top performance no matter the conditions. That's why he relies on NorthStar batteries.

"Half a day that I could lose on a Bass Master event and the Classic's gone," he says. “NorthStar builds the best deep cycle battery I've ever been around. They are very heavy batteries, because they use 100% pure lead. These are long lasting batteries - when I charge up at the end of the day, they are only 33% down, because they are very strong, durable batteries."
