12v 250ah gel battery high quality solar battery
(SRG250-12)Gel series batteries are designed to meet the requirements of frequent cyclic and high temperature applications. Such as broadband, PVs etc through up-to-date gel technologies. Our gel batteries uses German origin high purity fumed silica to form sulfuric acid thixotropic Gel and fills to the batteries with vacuum to ensure the fully penetration of electrolyte through separators and plates pastes.
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.
ApplicationUPS, Broadband, Electric powered vehicles, Electric powered toys, Vacuum cleaners, Medical Equipments, Goof cars and buggies, Wheel chairs, PVs, solar systems, control systems, power systems, wind energy systems, telecommunication /communication systems & etc.
