Deep Cycle Batteries vary from regular car power packs, even though they look quite similar. Deep Cycle Batteries are intended to provide a stable power over an extended stretch of time, usually till the battery gets discharged significantly. Car Batteries in contrast are designed to supply the required short bursts of high energy to begin the car. Hence, they are also known as Starter Battery power. Once the car can be started, the car’s alternator will kick-in and produces the mandatory power. An important difference between Deep Cycle Batteries plus regular Car Batteries is deep cycle batteries is usually discharge up to 80% involving its capacity (although it isn't recommended to discharge some sort of battery below 50%), whereas the car battery has to be almost fully charged all the time i. e.,they may be discharged only to a tiny % of their volume (usually, 2% to 5%) before these are recharged. So, where will be Deep Cycle Batteries applied? They are used in applications where it is necessary for the battery and therefore deliver sustained / stable power over a good , long duration. The first application that concerns mind is the UPS as well as Uninterruptable Power Supply. A number of the other applications of Deeply Cycle Batteries are: The game of golf Carts RVs Boats (and other Marine applications) Wheel Chair Electric Vehicles (EVs) Crisis Lighting Medical Devices Alternative Fork Lifts and Ground Sweepers Off-grid Energy Backup (Solar, Wind) There may be a right deep cycle battery for each need. If you are looking for a Deep Cycle Power supply, then you have to know some important specs of the battery so that you can analyze the battery before making a purchase. Type: There are two forms of deep cycle batteries – Lithium-Ion and also Lead Acid (Flooded, AGM and Gel). Of these a couple, the lead-acid type dominates market trends while the Lithium-Ion electric batteries are slowly becoming popular. Capacity: This capacity score is given in Ah (Amp Hour). Simply communicating, the ‘Ah’ rating of an battery specifies the number of current a battery can supply for just a certain duration. Discharge Cycle: It represents how oftentimes the battery can often be discharged and recharged. It is better to aquire a model with higher launch / charge cycles for durability. https://www.mcabattery.com/Deep-Cycle-Agm-Battery-pd47975414.html
