18 Reference information
This section provides information about your phone's batteries,
enhancements, chargers, safety guidelines and technical information.
Be aware that the information in this section is subject to change as
batteries, chargers, and enhancements change.
• BATTERIES AND CHARGERS
This phone is intended for use when supplied with power from the ACP-7U,
ACP-8U, and LCH-9 chargers. Other usage could invalidate any approval
given to this apparatus and might be dangerous.
Charging and Discharging
Your phone is powered by a rechargeable battery.
Note that a new battery's full performance may be achieved only after
two or three complete charge and discharge cycles!
The battery can be charged and discharged hundreds of times but it will
eventually wear out. When the operating time (talk time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer and recharge your
battery only with the chargers approved by the manufacturer. Unplug the
charger when not in use. Do not leave the battery connected to a charger
for longer than a week, since overcharging may shorten its lifetime. If left
unused, a fully charged battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge;
allow it to cool down or warm up first.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged or worn out.
Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object (coin, clip, or pen) causes direct connection of the
+ and - terminals of the battery (metal strips on the battery), for example,
when you carry a spare battery in your pocket or purse. Short-circuiting
the terminals may damage the battery or the connecting object.
