COLD WEATHER MAINTENANCE FOR BATTERIES(continued)BATTERY COLD WEATHER MAINTENANCEPRACTICESThe batteries can stay on the A/C if:- the Outside Air Temperature (OAT) stays higher than -15 °C (+5.00°F),- the OAT is approximately -15 °C (+5.00 °F) for not more than 12hours,- the OAT is between -15 °C (+5.00 °F) and -30 °C (-22.00 °F) fornot more than 6 hours.You must remove the 3 batteries if the OAT is lower than -30 °C(-22.00 °F).You must respect the temperature limit, otherwise you can decreasethe life of batteries, or you can damage them.NOTE: We recommend that you use a Ground Power Unit (GPU)to start the APU if the OAT was lower than -15 °C (+5.00°F).
