Chapter12 Battery Operation Notes
12.1 EKG312T is designed with built-in full-sealed and non-maintained rechargeable lithium
battery, also equipped with perfect auto-charging-discharging monitor system. When EKG312T is
connected to AC power supply, the battery will be charged automatically. Battery status will be
displayed on right edge of LCD screen(see 12.4) in powering on state. It needs about 4 hours to
charge the battery full after absolute discharge.
12.2 EKG312T can continuously print for 90 minutes and work 4 hours in standby mode when
battery is completely charged. When EKG312T is powered by battery, there will be a battery
indicator in LCD screen of the front panel, showing the battery capacity in 5 modes. When the
battery capacity is too low for EKG312T to operate, EKG312T will turn off automatically to avoid
forever damage to the battery owing to over-discharged.
12.3 The battery should be recharged in time after discharged completely. If not used for long, the
battery should be recharged every 3 months, which can extend the service life of the battery.
