Small 12 volt deep cycle battery12/15/2023 ![]() ![]() ![]() Type: There are two types of deep cycle batteries – Lithium-Ion and Lead Acid (Flooded, AGM and Gel).If you are in the market for a Deep Cycle Battery, then you have to be aware of some important specs of the battery in order to analyze the battery before making a purchase.īelow are the three main considerations to check out… There is a right deep cycle battery for every need. Industrial Fork Lifts and Floor Sweepers.Some of the other applications of Deep Cycle Batteries are: The first application that comes to mind is the UPS or Uninterruptable Power Supply. So, where are Deep Cycle Batteries used? They are used in applications where it is necessary for the battery to be able to deliver sustained / stable power over an extended duration. Once the car is started, the car’s alternator will kick-in and produces the required power.Īn important difference between Deep Cycle Batteries and regular Car Batteries is that deep cycle batteries can be discharge up to 80% of its capacity (although it is not recommended to discharge a battery below 50%), whereas the car battery must be almost fully charged at all times i.e., they can be discharged only to a small % of their capacity (usually, 2% to 5%) before they are recharged. Hence, they are also known as Starter Batteries. Deep Cycle Batteries are designed to provide a steady power over an extended period of time, usually till the battery gets discharged significantly.Ĭar Batteries on the other hand are designed to supply the necessary short bursts of high energy to start the car. We’re not implying that you would use your boat when the temperature is 0☏.Deep Cycle Batteries are different from regular car batteries, even though they look quite similar. 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. ![]()
