Installation and setup
After battery installation, the battery may have enough charge to allow some
calls. For best performance, place the handsets in the telephone base or the
charger and allow to charge for 16 hours before use.
You can keep the battery charged by returning the handsets to the telephone
base or the charger after use. When the battery is fully depleted, a recharge
takes about 12 hours. The average talk time on a fully charged battery is
about eight hours, and the standby time is approximately five days. Actual
battery life depends on usage conditions and age of battery.
