GFM Series (2V)

The 2V VRLA Deep Cycle AGM Batteries are of the latest technology. These products can be widely used as backup power for telecommunication, UPS, Power plants, transmission substation, security system, microwave relay station, remote sensing device, emergency light system, mobile measuring equipment, power supply system, military facilities, railway signaling and auto control equipment.

Features:

  • AGM Technology
  • RatedVoltage: 2V
  • Capacity Range (C₁₀): 200AH - 3000AH
  • 10 Years Design Life (25°C)
  • Flame Retardant Container & Cover with ABS Material
  • HighReliability & Long Service Life

Product Characteristics:

  • The plate is with the structure of big grid and block, and is made of special alloy through special process of quadribasic lead sulfate, which improves specific energy of the battery and prolongs the cyclic service life
  • Positive grid is made of special multi alloy. It has long service life under both float and cyclic applications
  • Separator, made of AGM, low internal resistance and good high rate discharging performance
  • Active materials, special additive has been added into the lead paste of positive and negative plate, so that the utilization rate of active materials will become high and it will improve the charge acceptability
  • High purity electrolyte and special additive are used, which lead to low self-discharge
  • Special terminal sealing structure, unique assembled maze seal structure of terminal (patented technology) ensures the safety and reliability of seal
  • Safe valve structure, the valve is made of fire resistant ABS materials. The valve core is in column structure, there is dual-filtering acid mist filters. It has the function of correctly controlling the pressure, flame resistance and acid mist filtering when valve open and close
  • Adopt U double-layer longitudinal pattern and tight assembly technology to prevent plate stress from affecting separator elasticity. Large diameter copper core is applied, the terminals and comb teeth are die casted together, which makes the internal resistance lower
  • Short circuit protection, plastic sleeve is added for plate, so as to effectively avoid the short circuit of the positive and negative plate, and to avoid the bend and distortion in the horizontal installation
  • Inert gas protect welding is used, special glue is applied for the second sealing to ensure no leakage
  • Single cell structure, the single cell structure with the max capacity up to 3000AH, offering the customers more choices
  • System structure, battery can be installed in cabinet, on rack and floor. Thermal dissipation space has been laid out to effectively void thermal runaway
