Important Battery Information
•
Note that a new battery’s full performance is 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 notice-
ably shorter than normal, it is time to buy a new battery.
•
Use only batteries approved by the phone manufac-
turer and recharge your battery only with the chargers
approved by the manufacturer.
•
When a charger is not in use, disconnect it from the
power source. Do not leave the battery connected to
a charger for longer than a week, since overcharging
may shorten its life. If left unused a fully charged
battery will discharge itself over time.
•
(NiMH batteries only) For good operation times,
discharge the battery from time to time by leaving
your phone switched on until it turns itself off (or by
using the battery discharge facility of any approved
accessory available for your phone). Do not attempt
to discharge the battery by any other means.

•
Temperature extremes will 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 cir-
cuiting can occur when a metallic object (coin, clip, or
pen) causes direct connection of the + and - terminals
of the battery (metal strips on the back of 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.
•
Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce
the capacity and lifetime of the battery. Always try to
keep the battery between 59º F and 77º F (15º C and
25º C). A phone with a hot or cold battery may
temporarily not work, even when the battery is fully
charged. NiMH batteries’ performance is particularly
limited in temperatures below 14º F (-10º C). Li-Ion
batteries’ performance is particularly limited in
temperatures below 32º F (0º C).
•
Do not dispose of batteries in a fire!
•
Dispose of used batteries in accordance with any
local regulations.
