Pack more amp-hours and cranking amps into a smaller space with a slim-line AGM battery AGM Batteries are great in both deep cycle and starting applications. They charge more quickly than conventional batteries, have low 3% monthly self-discharge rates and aremaintenance-free—no need to add water. The spill-proof, valve-regulated design eliminates acid spills and terminal corrosion. AGM batteries are safer to operate thanconventional flooded batteries, as the chance of explosion or acid spray is reduced which allow them to be installed in almost any location and any position (exceptupside-down). Northstars 480 slim-line AGM batteries offer great resistance to vibration, provide high cranking amps and are capable of cycling 900 times at 50% of their capacity. The durable heat resistant case will give you the confidence they will stand up to years of abuse in the marine environment. Because these batteries can be installed on their side, they provide way to save space and keep the center of gravity low. Threaded inserts allow low profile terminal connection or to match the terminals (not included) to the existing battery cables. Key Features Threaded terminal inserts allow low profile installation or change terminals to match existing batter cable ends Able to Cycle 900 times to 50% depth of charge Able to handle repeated high demands such as trolling motors or start-stop vehicles Durable and heat resistant plastic housing Fast charging and no maintenance Made in the US Specifications Group Size: Specialty Terminal Type: Bolt in Amp Hours (Ah): 217 Cold Cranking Amps (CCA): 1420 Marine Cranking Amps (MCA): 1740 Reserve Minutes: 477 Weight: 152 lbs.
