TECHNICAL FEATURES

• Global´s PzS and PzB series are compliant to DIN EN 60254-2.
• Positive Grid

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 Cell

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 Separator

Microporous polyethylene separators assure ionic circulation and low internal resistance.

• Rubber Bushing

Rubber bushing around terminal protects covers breakage and keeps plates safe from external shocks and vibration.

• Heat-sealed Case and Cover

The cases and covers are made of polypropylene, which are high impact-resistant and heat-sealed for perfect leak-proof assembly.

• Push in Flip Plug

Flip plug with electrolyte indication.

• Cell connection for bolt-on type

Bolt-on type terminals allow cells to be replaced or moved without excessive work.

• P.E Tube

P.E tube is more environmental friendly compared to Glass Tube, contributed by no use of phenol resin.

•Wet-Filler

By equalizing the weight of positive plate, wet-filling has an advantage in reducing capacity variation among each cells
