What failure message is displayed for a battery failure?

• A. BATTERY ERROR
• B. BAT FAIL
• C. POWER LOSS
• D. CELL FAIL

Answer: (B)

When a fault involves the power source itself, the system uses a concise, standardized code to communicate it quickly. The battery failure message is simply the short label that pinpoints the exact issue: the battery has failed. This direct wording is designed for rapid recognition and action, such as checking battery health, connections, or switching to an alternate power source.

Other options are less precise for a battery fault. A generic “BATTERY ERROR” could cover a broader range of issues and isn’t as specific about the fault being a failure. “CELL FAIL” would imply a problem with a single cell rather than the entire battery system, and “POWER LOSS” is too general and could reflect issues outside the battery itself. The clear, unambiguous indication you’d expect in this scenario is the battery failure label: BAT FAIL.
