Precautions When Using Batteries - Samsung SGH-X838 User Manual

Health and safety information
operate at multiple power levels so as to use
only the power required to reach the network.
In general, the closer you are to a base station,
the lower the power output of the phone.

Precautions when using batteries

• Never use a charger or battery that is
damaged in any way.
• Use the battery only for its intended
purpose.
• If you use the phone near the network's
base station, it uses less power. Talk and
standby time are greatly affected by the
signal strength on the cellular network and
the parameters set by the network operator.
• Battery charging time depends on the
remaining battery charge, the type of
battery, and the charger used.

The battery can be charged and discharged
hundreds of times, but it will gradually wear
out. When the operation time is noticeably
shorter than normal, it is time to buy a new
battery.
• If left unused, a fully charged battery will
discharge itself over time.
• Use only Samsung-approved batteries, and
recharge your battery only with Samsung-
approved chargers. Disconnect the charger
from the power source when it is not in use.
Do not leave the battery connected to a
charger for more than a week, since
overcharging may shorten its life.
• Extreme temperatures will affect the
charging capacity of your battery: it may
require cooling or warming first.
• Do not leave the battery in hot or cold places
because the capacity and lifetime of the
battery will be reduced.
