22. BATTERY OPERATION OVERVIEW 5 4 BATTERY OPERATION OVERVIEW The infusion system is intended to operate on battery power on an exception basis only such as emergency backup or temporary portable operation Examples of emergency backup include AC power failure or inadvertent disconnection of the AC power cord An instance of temporary portable operation includes patient transfer from one location to another The device should be connected to AC power whenever possible to allow the battery to remain fully charged The line power indicator turns off when the infuser is operating on battery power The backlight extinguishes after approximately one minute of operation on battery power Factors that most commonly affect battery life are the depth and frequency of discharge and the length of the recharge period As a general rule the more often the battery is discharged and recharged the sooner it will need replacement The primary cause of damage is leaving the battery in a less than fully charged state for any period of time Battery damage can occur in a matter of hours and cause a permanent loss of battery capacity The amount of lost capacity depends on the degree of discharge the storage temperature and the length of time the battery was stored in a discharged state Note permanently damaged battery cannot be recharged to full capacity When the battery discharges below the acceptable level while the infuser is operating the audi
