16.5 RTC Battery Life Expectancy and Shelf Life
The RTC battery in the IMS is rechargeable, not field replaceable, and has a life expectancy of
10 years, but a shelf life of only 1 year. The unit shows a warning when there is one
year remaining.
It is the owners responsibility to keep the RTC battery charged when IMS units are in storage
by powering it up once every 12 months (6 months is highly recommended). It takes 60 hours
for a full charge.
