The listed battery backup time (8 hours) is the nominal initial time that the battery pack can provide standby power after loss of AC power
and after fully charging the battery. Due to variations in individual units, the actual initial standby time can vary +/- 10%. Other factors can also
influence battery standby power times such as CPE data activity, variations in DOCSIS traffic, telephone port activity, battery aging, and
temperature.
