  • Changhong Gas recombination ultra-low maintenance Ni-Cd rechargeable battery adopts negative oxygen recombination technology and gas recombination vent plug technology, therefore, the water consumption inside the cell is ultra-low, which are widely applicable for electric power, telecommunication, mass transit, metallurgy, mining, lighting, UPS power supply and other devices as standby DC power supply, as well ad energy storage power for solar and wind energy.
  • Sichuan Changhong Battery Co., Ltd. is a large-scale enterprise of professionally manufacturing nickel iron rechargeable battery, who has decades’ experience on manufacture, development, maintenance, after-sale service of ni-fe battery. With advanced equipment and continuous technical development, the products of Changhong, with excellent performance and reliable quality, has exported to several countries and regions all over the world.
    Changhong Ni-Fe rechargeable battery has the characteristics of lower cost-in-use, minor self-discharge, long service life, low maintenance (more than 3 years), environmental-friendly, high mechanical strength, excellent resistance performance to electric abuse, good resistance to over-charge and over-discharge, therefore, Ni-Fe battery can replace Ni-Cad battery in many fields. After Changhong Ni-Fe battery is charged according to standard charging system under the ambient temperature of 20℃±5℃, the battery can be normal used under the ambient temperature of -20℃±60℃(different discharge capacity under different temperature).
