Replacement of Sealed Nickel-Cadmium Batteries on Ch-53e and Mh-53e Aircraft with Sealed Lead-Acid Batteries
This paper will summarize the details of replacing the CH-53E and MH-53E crashworthy batteries to improve system reliability, safety of flight and to reduce battery maintenance and battery maintenance costs. A flight evaluation program is presently underway at Marine Corps Air Station (MCAS) New River, North Carolina to validate the proposed change from Sealed Nickel-Cadmium (SNC) batteries to Sealed Lead-Acid (SLA) batteries. Under the sponsorship of the Commander, Naval Air Systems Command the Crane Division, Naval Surface Warfare Center identified a SLA battery as a replacement for the SNC battery currently being used in the CH-53E and MH-53E aircraft. The replacement battery is a direct form, fit, and function replacement for the SNC battery. It is presently planned that the SLA battery will have a one-year inspection period and a replacement cycle of three years.
