118 Guidelines for Safe and Efficient Use
New Batteries
The battery delivered with your phone is not fully charged.
Battery Use and Care
A rechargeable battery has a long service life if treated properly. A new
battery, or one that has not been used for a long period of time could have
reduced capacity the first few times it is being used.
• The talk and standby times depend on the actual transmission conditions
when using the phone. If the phone is used near a base station, less power
is required and talk and standby times are prolonged.
• Use only batteries manufactured by Ericsson and the AC/DC adapter
supplied with your battery charger. Using accessories not manufactured by
Ericsson may be hazardous and the warranty does not cover product
failures caused by the use of non-Ericsson original accessories.
• Do not expose your battery to extreme temperatures, never above
+60°C (+140°F).
• For maximum battery capacity, use your battery at room temperature.
If the battery is used at low temperatures, the battery capacity will
be reduced.
• The battery can only be charged when the temperature is between +5°C
(+41°F) and +45°C (+113°F).
• Turn off your phone before removing the battery.
• Use the battery only for its intended purpose.
• Do not attempt to take the battery apart.
• Do not let the metal contacts on the battery touch other metal objects.
This may short-circuit and damage the battery.
• Do not expose a battery to open flames. This may cause the battery
to explode.
• Do not expose a battery to liquids.
• Never place the battery in your mouth. Battery electrolytes may be toxic if
swallowed.
Your phone manufacturer is a member of the Rechargeable Battery Recycling
Corporation (RBRC); a non-profit public service organization designed to
assist in the recycling of rechargeable batteries. Many areas require recycling
of rechargeable batteries. In the U.S., call 1-800-822-8837 for information on
how to recycle your battery. Outside the U.S., contact your local retailer for
recycling instructions.
