Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Move the mower/base out of direct heat if safe to do so.
2. Allow the battery to return naturally to operating temperature.
3. Do not cool or heat the battery artificially.
4. Check whether the base is installed in persistent direct sun.
5. If the error occurs at normal ambient temperature, investigate battery temperature sensing/battery health.
