Laboratory Shelf Life Tests of Primary Reserve Magnesium Batteries for Emissive Expendable Electronic Countermeasure Devices
Abstract
This report presents results of shelf life testing of automatically activated, magnesium anode batteries developed for aircraft expendable electronics countermeasure (ECM) application. Model LSP2055 batteries stored at 70F for over 12 months (continuous) demonstrated design service life as did one battery that was desk stored at about 75F for 45 months. However, Model LSP2055 batteries stored at 130F for 12 months (continuous) and at 110F for 12 months (continuous) failed to give minimum service life. These high temperature stored batteries lose water from their electrolyte via evaporation resulting in a too acid electrolyte. Model LSP2021 batteries, similar in most respects to Model LSP2055 batteries, demonstrated their specified discharge life following 6 years desk storage at about 75F. Although some mechanical causes necessitated some batteries to be manually activated, the general conclusion, based on fresh battery performance and shelf life test results, is that Model LSP2055 battery is a suitable power source for aircraft ECM applications.
