LongWin forcus on QUALITY and DURABILITY of VRLA battery and GEL battery on top place, won certificates of CE, UL, IEC, MSDS, Safe sea transport, Non dangerous test…
1. Container/Cover: Made of UL94HB and UL 94-0ABS Plastic, fire resistance and water proof.
2. Negative Plates: Use the special PbCa alloy grids, optimize the recombination efficiency and less gassing.
3. Positive plates: PbCa grids minimize corrosion and prolong life.
4. Terminal post: Copper or lead material with maximum conductivity, enhance the high current rapidly.
5.Vent Valve: Allows the release of the excess gas automatically for safety.
6. Three steps of Seal procedures: Ensure battery completely sealed with safety, never leakage and volatile acid, longer life.
7. Silicone GEL electrolyte: Import from Germany Evonik famous brand silicone.
