Battery life expectancy on the Mediation Server Module for OCS

The Mediation Server Module ships with a battery installed. The typical
life expectancy of the 170 mAh battery (VARTA CR2025) is 5–6 years
assuming an average "on" time of 8 hours for each working day at an
operating temperature of 30 C. However, this value varies considerably
because the life expectancy is dependent on the operating temperature
and the standby time (shutdown time) of the system in which the battery
operates. To ensure that the lifetime of the battery is not exceeded, Nortel
recommends that you exchange the battery every 4–5 years.
