The power-on time ratio is the ratio of programmable controller power-on time to one day (24 hours).
(When the total power-on time is 12 hours, the ratio is 50%. When the time is 6 hours, the ratio is 25%.)
The guaranteed value is a battery life at 70°C, which is calculated based on the characteristics of manufacturer-supplied
memories, when the battery is stored within the ambient temperature range of -25 to 75°C (or used within the ambient
temperature range of 0 to 55°C).
The actual service value is a battery life calculated based on the values measured at storage ambient temperature of
40°C. This value is intended for reference only because it varies depending on the characteristics of the components.
SM52 turns on even when the battery connector is disconnected or the lead wire of the battery is disconnected. In this
case, the battery stops working. The CPU module may lose data when the backup power time (three minutes) is elapsed
after power-off.
