life for a new battery pack The network in use and the condition of the
battery pack can affect battery life. Avoid areas of poor reception. Ensure batteries are fully
charged. Additionally, for NiMH batteries, ensure batteries are
also discharged fully before recharging.
Short battery life for an
old battery pack The battery pack was worn out. Replace with a new one.
Short battery life for Ni-
MH battery pack The life of the battery pack is affected by
improper charging, this is inherent in all Ni-
MH batteries. To maintain maximum performance, always use until the Low
Battery Warning appears and then fully recharge the battery
pack. To revive a Battery Pack, use the telephone until the
Low Battery Warning appears and then fully recharge three
times. However, if the battery life still is short, the battery pack
has eventually worn out. Replace with a new one.
