What is the memory item for battery overtemperature?

• A. Affected Battery...OFF
• B. Battery temperature stabilizes automatically
• C. Battery remains online until APU shutdown
• D. Reset the OVTEMP warning manually

Answer: (A)

The memory item for a battery overtemperature is to switch the affected battery OFF. When a battery overheats, the immediate priority is to isolate the heat source to prevent further heating or a potential thermal event. Turning the affected battery OFF quickly removes power from the overheated cell, reducing risk to the electrical system and allowing remaining power sources to be used if needed. The other options don’t address the hazard as directly: assuming automatic stabilization isn’t reliable in an overtemperature condition, keeping the battery online risks continued heating; waiting for shutdown events (like APU) isn’t part of the immediate item; and resetting the warning doesn’t remove the hazard or stop the overheating.
