Deka 24M5 Marine Master 12 Volt 550 CCA/ 675 CA Marine/RV Starting Battery (Gr 24)
Starting Power – High Marine Cranking Power
In the starting mode, a gas or diesel marine engine (inboard, outboard or auxiliary type) places a demand for high amperage, or starting current, to “crank the engine” up to starting RPM. This high starting current must be delivered quickly and for as long as thirty seconds at a time, month after month after month. Otherwise, the engine cranks too slowly and may not start at all...especially if the battery has been sitting for long periods, is extremely hot, has been drained by an auxiliary load, or the engine is in an untuned condition. In any event, you can’t start. All you can do is float.
Why risk a potentially dangerous “no-start” condition by purchasing an inexpensive, “bargain basement, sale of the week,” so-called marine battery? Many times these inexpensive batteries are nothing more than cheap car batteries with fancy marine labels. Yes, they may work for a while...but sooner or later they will let you down...at the worst possible time, in the worst possible situation.
When it comes to batteries, you really do get what you pay for. And with DEKA , you get quality features and benefits that no other manufacturer can provide. DEKA MARINE MASTER STARTING BATTERIES are available in a wide range of power capacities...from medium duty to super heavy-duty, delivering over 1000 cranking amps of power!
