Battery Charging - AT&T EL52100 Quick Start Manual

Battery charging

Once you have installed the battery, the screen indicates the battery
status (see the following table). If necessary, place the handset in
the telephone base to charge the battery. For best performance,
keep the handset in the telephone base when not in use. The
battery is fully charged after 10 hours of continuous charging. See
page 32 for battery operating times.
If the screen is blank, you need to charge the handset without
interruption for at least 30 minutes to give the handset enough charge to use the
telephone for a short time. The screen shows LoW BaTTErY until you have charged the
battery without interruption for at least 30 minutes. The following table summarizes the
battery charge indicators and actions to take.
