Effects of Water Salinity and Temperature on MK 72 Sea Water Battery Function

Abstract

Non-ignition failures occurred during acceptance testing of Lot 2-KC-72 of Mk 25 Marine Location Markers (MLM) from the Kilgore Corporation at NATC Patuxent River, Maryland (Pax River). Previous testing at NAD Crane in standard sea water solution had proven successful. A detailed study of the Mk 72 Sea Water Battery was conducted to observe the relationship between solution temperature and salinity and the resulting voltage obtained from the battery. Tests conducted with the battery drop test fixture as specified by OS 8765 indicated, at a temperature of 40F, a minimum salinity of 1.5 percent was necessary to enable the battery to meet specifications.
