NOTE: NOTE:
The user must be aware that the battery’s operational tempera-
ture range is less than that of the aTCA-6155’s storage temper-
ature range. For exact temperature range information, refer to
the battery manufacturer’s specifications.

The typical life expectancy of a 225mAh battery is 4-5 years
with an average on-time of 8 hours per working day at an oper-
ating temperature of 30°C. However, this typical value varies
considerably because the life expectancy is dependent on the
operating temperature and standby (shutdown) time of the sys-
tem in which it operates. To ensure that the lifetime of the bat-
tery has not been exceeded, it is recommended to change the
battery after 3-4 years.
