ODYSSEY Drycell Extreme batteries are deep cycle super high cranking new technology batteries. These Extreme Odyssey dry cell military grade batteries are capable of providing engine cranking pulses in excess of 2150A for 5 seconds as well as 400 charge/discharge cycles to 100% depth of discharge. A standard starting, lighting and ignition (SLI) battery can only do one or the other, but not both. An ODYSSEY battery is your best choice for short duration high amperage pulse or low rate long duration drains. They each come with a full national warranty (2, 3, or 4 year warranty). They can mount in any position and any place. The steel or metal jacket is perfect for severe use applications if needed. The brass terminals used on some models (T terminal) are non corrosive battery terminal. BatteryPlex is you source for all of your Odyssey Hawker Dry Cell AGM battery.
