2V 1500ah Deep cycle batteries SR1500-2Solar 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 Structure1. 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.
ApplicationSolar 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· Long service life: Designed life is over five years.
