This Ultra-Lightweight battery is the best on the market for cutting pounds while still offering at least a full day of run time on sonar units with screens up to 7". It drives an incredible 36+ hr run time on traditional flasher units! This little power house is the same dimensions as a standard flasher battery (151x65x94 mm), but weighs in at only 1.4 lbs.
Don't store your battery for the winter. NORSK batteries include a patent pending LED indicator and Dual USB accessory ports! Keep your phone charged and power accessories during all of your outdoor adventures.
800+ charge cycles, 2 year limited warranty!
