The NCSPB-25150 is a sintered plate technology Nickel Cadmium Rechargeable Battery used as emergency power source and for internal engine starting. This battery consists of 20 cells of HBLNIFE Type NCSPC-25150-4 (at 2.5 hour rate) housed in a stainless steel container. Each cell is provided with a vent valve to release gases evolved in the cell. The power take-off is through connector incorporated to suit aircraft requirements.
The battery is supplied in electrolyte filled, formed and discharged condition.
The battery manufactured by HBL NIFE meets the appliance design approval and specification requirements of Inter State Aviation Committee, Moscow, Russia & DGAQA (Directorate General of Aeronautical Quality Assurance) Ministry of Defence, Govt. of India and directorate General of Civil Aviation, India.
