A 12V AGM (Absorbent Glass Mat) deep cycle battery is a type of battery commonly used in applications that require a steady and reliable power supply over an extended period. AGM batteries are constructed using a special design that incorporates a fiberglass mat between the battery plates, which absorbs and immobilizes the electrolyte. This construction makes AGM batteries spill-proof, maintenance-free, and resistant to vibration.
Deep cycle batteries are specifically designed to provide a consistent level of power over a long duration, making them suitable for applications such as recreational vehicles (RVs), boats, solar power systems, electric vehicles, and backup power systems.
The "12V" in the battery's name refers to its nominal voltage, which means the battery's average voltage output is around 12 volts. However, it's essential to note that the actual voltage can vary depending on the battery's state of charge. A fully charged 12V AGM deep cycle battery typically measures around 12.8 to 13.2 volts.
