Northstar NSB-AGM 31M Group 31 Battery

NorthStar Marine Batteries excel at providing high vibration resistance, with the high cranking amps and reserve capacity that watercraft demand.

Northstar Batteries knows that conventional lead acid batteries use lead alloys with additives which increase the strength so they can withstand handling during the battery making process. The downside of using these alloys and additives is that the batteries suffer from faster corrosion and component aging. Our advanced manufacturing process eliminates the need for these alloys and additives - our pure lead plates can be made thinner and larger, which means more surface area for active material reactions, which increases power density. This is why NorthStar Batteries deliver superior cranking, unrivaled cycling, faster recharge, high vibration resistance, longer life with minimal maintenance and virtually no internal grid growth. Unlike conventional batteries, NorthStar Batteries never experience catastrophic failures. NorthStar Batteries features include:

  • Pure lead AGM technology delivers exceptional CCA ratings and reserve capacity cycling ability
  • Quick starting every time
  • Cycles over 900 times to 50% depth of discharge
  • Faster recharge than conventional batteries
  • Proudly made in the USA at our state-of-the-art battery plant
