11.3.2 Battery lives of CPU modules
(1) Battery (Q6BAT) lives of Basic model QCPUs
* 1: The power-on time ratio indicates the ratio of programmable controller power-on time to one day
(24 hours).
(When the total power-on time is 12 hours and the total power-off time is 12 hours, the power-on
time ratio is 50%.)
* 2: The guaranteed battery service life; equivalent to the total power failure time that is calculated
based on the characteristics value of the memory (SRAM) supplied by the manufacturer and
under the storage ambient temperature range of -25 to 75 (operating ambient temperature of 0
to 55 ).
* 3: The actual battery service life; equivalent to the total power failure time that is calculated based on
the measured value and under the storage ambient temperature of 40 . This value is intended
for reference only, as it varies with characteristics of the memory.
* 4: In the following status, the backup time after power OFF is 3 minutes.
•The battery connector is disconnected.
•The lead wire of the battery is broken.
