Product Details

DC12-55-Y of Sealed AGM Battery

Solar batteries are an intricate component for off-grid electrical systems such as solar, wind, and mini hydroelectric systems.

All these systems produce DC electrical which must be stored so that it may be used at a later time. In order to do this at the present time we use deep cycle batteries.

Deep cycle batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the batteries unlike that of other batteries such as cranking batteries which are used to start vehicles.

The innovative Gel Technology does not only combines the advantages of lower internal resistance of deep cycle battery , but also do have much much better thermal stability and longer cyclic life .

Product Description of Sealed AGM Battery

1. Eco-friendly and Free Maintenance

Using new technologies for the production technique: combines with SiO2 and lead acid, with high-quality polymer materials.

Pollution-free: During the process of operating, there is no pollution-caused in surrounding area. The standard of the environmentally-friendly, green production conforms to internationally recognized standard.

2. Long-term Life Cycle

Full silica Gel is utilized to ensure extremely long cycle life and excellent performance under high temperature. No water needed in the process of using. no acid mist and no sulfuric acid spilled. Using special material-silicon sulfide, negative plate with low interference on curing lead, positive plate with low shelling.

3. Low Self-discharge

Designed to comply with high quality and natural raw materials and a set of strict production process.
