Changhong / Nickel iron Battery / energy storage application

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).
