Starting batteries, such as car batteries should not be used for deep cycle applications because of the thinner plates in these batteries. Perfect for applications requiring large amounts of power. Otherwise, the battery is completely sealed and is therefore, maintenance-free, leak-proof and usable in any position. Should the battery be accidentally overcharged producing hydrogen and oxygen, special one-way valves allow the gases to escape, avoiding excessive pressure build-up. The dilute sulfuric acid electrolyte is absorbed by separators and plates, thus immobilized. In general, AGM batteries have less instant energy, but greater long-term energy delivery. The extra thick lead plates in this battery allow for a deeper discharge, providing more amp capacity, with less harm to the battery. This line of batteries is more heavy duty and provides 20% more charge/discharge cycles compared to other AGM batteries. Affordable without compromising quality, these batteries will provide power for years. We’re not implying that you would use your boat when the temperature is 0☏.The AIMS Power AGM battery product line is heavy duty, deep cycle, ideal for back-up power and stored power applications. Note: The temperatures mentioned above in regard to CCA and MCA are used to standardize the measurement.
Marine Cranking Amps (MCA) are identical in concept to CCA, except that they are measured at 32☏, which makes the numbers higher. What this means to boat owners is that large engines, especially diesels and high compression gas engines require a high CCA rating. Technically, this is the number of amps a battery can deliver at 0☏ for 30 seconds without having the voltage drop below 7.2 volts. The term “Cold Cranking Amps” is used to quantify a battery’s ability to crank over an engine. A battery’s group number does not imply purpose, capacity, quality or other characteristics.
Battery group numbers denote the size of the case, location of the battery terminals and general configuration. Just like the batteries used to power flashlights or drum-beating pink rabbits (D, C, AA, etc.), boat batteries come in standard sizes designated by their Group number. Your choice of battery chemistries should be based on the performance you desire balanced against how much you are willing to spend. Battery ChemistriesĮach of the battery types mentioned above is offered with a choice of battery chemistries, which are flooded lead acid, gel, AGM (Absorbed Glass Matt) and most recently, Lithium Iron Phosphate, such as those supplied to us by Relion. Dual-purpose batteries can be used for starting engines or powering house loads. Batteries designed for running loads are called house or deep cycle batteries. Those designed for starting engines are called cranking or starting batteries. There are three types of boat batteries: Starting batteries, deep cycle batteries and dual-purpose batteries. When boats have charging devices like alternators, solar panels or wind generators, batteries store electricity so charging devices don’t have to operate simultaneously with items that require electricity.
Marine batteries store electrical energy so electrical loads like lights, motors and pumps can operate.
