A BATT 1 (2) OVTEMP Warning message occurs at what temperature?

• A. Above 70°C
• B. Below -70°C
• C. Above 100°C
• D. At 0°C

Answer: (A)

The main point here is how a battery, when it overheats, triggers a warning to protect the system. For this aircraft, the BATT 1 (2) OVTEMP warning comes on as soon as the battery temperature rises above 70°C. That 70°C threshold is set to alert the crew early, giving time to reduce load, improve cooling, or take other precautions before temperatures get higher or a fault develops. Temperatures far from this range don’t match the configured trip point. A reading in extreme cold (below -70°C) or around 0°C wouldn’t trigger an overtemperature warning, and while temperatures well above 70°C (like 100°C) would keep the warning active, the defined trigger is crossing the 70°C threshold.
