Battery charge controller

The T7406E incorporates a special handset battery charge controller that uses a four-stage charging program. The four-stage charging program sequences charging from a soft start to a fast charge, and then to a topping charge, followed by a maintenance charge.
This four-stage charge sequence presents an optimum-charging plan that helps maximize the overall life of the battery by managing two critical elements in the battery charging process: charge rate and overcharging protection. NiMh batteries do not exhibit memory problems. You do not need to drain the batteries before you recharge them.
Low battery status is indicated on the handset by the visual charge status on the display and the audible warning tone. The battery icon appears in the upper right-hand corner of the handset display. When the battery is low, the battery icon flashes. If the handset is in use and the battery is low, the battery icon flashes and a warning tone beeps every 15 seconds. If the phone is in standby mode, low battery status is not indicated.
