12V 75ah Industrial battery for solar system SR(75-12)
Solar series batteries with valve regulated lead acid use particular alloy and material technology design to ensure an excellent performance in various environments, especially high and low temp. Solar series batteries are optimal for storage and conversion of photovoltaic energy and wind energy.
Battery Structure
1. Container/Cover: Made of UL94HB and LU 94V-0 ABS Plastic
2. Negative Plates: Use the special PbCa alloy grids, optimize the recombination efficiency and less gassing.
3. Separator: Import high quality AGM separator.
4. Positive Plates: PbCa grids minimize corrosion and prolong life.
5. Terminal post: Cooper material with maximum conductivity, enhance the high current rapidly.
6. Vent Valve: Allows the release of excess gas automatically for safety.
Application
Solar street light system, solar power home system, Photovoltaic system, Alternative energy system, Electric Utility, Outdoor control equipment, Railroad Utility, control systems, power systems, wind energy systems, telecommunications/communication systems & UPS system & etc.
Characteristics
