Once a low-battery error has been detected, it will take 5 days (at an ambient temperature of 25°C or
less) before the battery fails if power has been supplied at least once a day.
Clock data can be retained by ensuring that the CPU Unit power is not turned OFF until the Battery
has been replaced.
Additional Information
The Battery will lose its charge faster at high ambient temperatures.
