Vision Group has been one of the largest battery manufacturers in the world. Our products are classified into two categories: Valve-Regulated Lead Acid Battery and Lithium-ion Battery. The VRLA battery includes AGM series, Deep Cycle series, Pure Lead series and Gel series; The Lithium-ion Battery covers Lithium cobalt oxide series, Lithium manganese oxide series and Lithium iron phosphate series.

Vision EV series batteries use advanced technology with a special designed grid and active material. They use anchored plates and a high impact reinforced polypropylene case which can withstand the most extreme environments and vibrations. The EV series uses a wide range of common commercial battery sizes for ease of fit into applications.

Vision EV Series Dry Cell Batteries provide superior performance, capacities and reliability. Using state of art dry cell technology the EV series is designed for environmentally sensitive areas that require enhanced cycle life capabilities in commercial, industrial, residential, and private applications. The maintenance-free (VRLA) construction and advanced design features makes the EV Series the definitive choice for a wide variety of applications.

What does deep cycle mean?

Deep-cycle batteries typically feature thick plates with a high-density active material. The thick battery plates allow for reserve energy to be stored deep within the battery plate and released during slow discharge such as trolling or electronic instrument use. The high-density active material remains within the batteries’ plate/grid structure longer, resisting the normal degradation found in cycling conditions. They are typically used where the battery is discharged to great extent and then recharged.

Deep Cycle refers to applications that typically discharge 60 to 70% or more of the battery capacity. An automotive battery is an SLI battery (Starting, Lighting & Ignition.) Its plates are designed to deliver maximum power for a short duration. Starting an engine typically discharges an SLI battery 3% or less. When an SLI battery is used in a deep-cycle application or in a vehicle with heavy accessory loads, the battery life will be shortened proportionally to how deeply and frequently it is discharged.

The VISION Deep Cycle battery uses a different chemistry for the plates’ active paste material, and a slightly stronger acid. This chemistry allows for a much longer life in deep cycle applications with only a slight reduction in maximum power output.
