KP series nickel-cadmium pocket type can bedivided into low rate (KPL), medium rate (KPM)and high rate (KPH) based on their dischargecurrent. It tailored for superior performance athigh temperature, high discharge, fast charge,long-term float or trickle charge. They have advantage of high power andenergy density, high efficiency ofcharge/discharge,a low cycle life, usually usedfor Railway DC power supply, Wind-energy/Solar systems, Telecom station,Lighting, UPS, Transport Vehicles etc.
