TECHNICAL FEATURES
The grids produced by high pressure casting system have an excellent advantage in cycle life of traction cell due to its anti-corossion characteristic.
Tubular type plates firmly hold active materials in right plate and solve the problem of shedding one and for all, and ensure you of high capacity, strong power and minimum defect.
Microporous polyethylene separators assure ionic circulation and low internal resistance.
Rubber bushing around terminal protects covers breakage and keeps plates safe from external shocks and vibration.
The cases and covers are made of polypropylene, which are high impact-resistant and heat-sealed for perfect leak-proof assembly.
Flip plug with electrolyte indication.
Bolt-on type terminals allow cells to be replaced or moved without excessive work.
P.E tube is more environmental friendly compared to Glass Tube, contributed by no use of phenol resin.
By equalizing the weight of positive plate, wet-filling has an advantage in reducing capacity variation among each cells
