TM 5-4320-300-14The specific gravity of a fully charged battery must be 1.250 minimum at 80°F (26. 6°C). Measure thetemperature of the battery electrolyte with an accuratethermometer. Compare the electrolyte temperature andthe hydrometer specific gravity reading to the batterycondition chart. Add or subtract (from your specificgravity reading) the decimal next to the temperature in °Fthat closely approximates the obtained electrolytetemperature. If the temperature corrected reading isbelow 1. 250, charge the battery. Coat battery terminalsand posts with a thin covering of MIL-G-10924 grease.Replace cover and wing nuts and tighten.e.Drain pump after use to prevent water in pumpfrom freezing. Remove pump body drain plug. Removeall fluid from pump body and replace drain plug.f.Cover unit when not in use.g.Shelter unit from weather, if possible.2-7.OPERATION IN EXTREME HEATa.Cooling. Keep engine and radiator clean to provide proper engine cooling. Keep centrifugal pump unit in openarea to allow air to circulate around the radiator and engine.b.Battery. Increase battery PMCS. Use distilled water or a good grade drinking water (excluding I mineral water)to bring electrolyte to proper levels.Change 1 2-61
