At 25°C, the battery life (maximum service life) for batteries is five years
whether or not power is supplied to the CPU Unit while the battery is installed.
This is the same as for CJ1G-CPU@@H CPU Units. The following table shows
the approximate minimum lifetimes and typical lifetimes for the backup battery
(total time with power not supplied).
