The ODYSSEYÆ Drycell battery combines in one box the characteristics of two separate batteries. It can deep cycle as well as provide enormous cranking power. These dry cell 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 (DOD). A typical starting, lighting and ignition (SLI) battery can do one or the other, but not both. Conventional batteries are either a sprinter or a long distance runner; An ODYSSEYÆ battery will do both ? provide short duration high amperage pulse or low rate long duration drains. * 3 year full warranty * 12 year military design * Drycell sealed technology * 60% more cranking power * Deep cycle design * Mount in any position - any place * Brass terminals, non-corrosive * Steel jacket for severe use Guaranteed longer service life - The ODYSSEYÆ battery, with a ten year design life and a three-to-eight year service life, saves you time and money because you do not have to replace your battery as often. It is also the ONLY battery that is capable of delivering a large number of deep cycles - up to 400 when fully discharged or up to 500 when discharged to 80%. Plus, the battery is specially designed for high vibration applications. Longer storage life - Unlike conventional batteries that need to be recharged every six to twelve weeks, the ODYSSEYÆ battery, when fully charged , can be stored for up to 2 years at room temperature (25∞C, 77∞F). At lower temperatures, storage times will be even longer. Superior cranking and fast recharge capability - The 5 second cranking power of ODYSSEYÆ batteries is double to triple that of equally sized conventional batteries, even when the temperature is as low as -40∞C. Also, with simple constant voltage charging (alternator or independant charger), there is no limitation on the inrush current, so the user is assured of fast charge recovery. Mounting flexibility - The ODYSSEYÆ battery may be installed in any orientation except inverted without sacrificing any performance attributes. Superior vibration resistance - ODYSSEYÆ batteries are of military grade and have endured very rigorous tests that demonstrate their overall ruggedness and exceptional tolerance of mechanical abuse. Worry-free shipping - The sealed Drycellô design of the ODYSSEYÆ battery eliminates the need for acid vent tubes so there is no more fear of acid burns or damage to expensive chrome or paint. Owing to the starved-electrolyte design, the US Department of Transportation (USDOT) has classified the ODYSSEYÆ battery as a dry battery, so it may be shipped worry-free by UPS/Federal Express or by air. Ready out of the box - ODYSSEYÆ batteries are shipped fully charged. If ODYSSEYÆ voltage is 12.65V or greater simply install the battery in your vehicle and you are ready to go! If below 12.65V, boost charge following the instructions in the ODYSSEYÆ Owner's Manual and/or Technical Manual. Maintenance free - No routine maintenance of ODYSSEYÆ batteries is required.
