Do not leave the battery in hot or cold places,
as this may deteriorate battery performance.
There is risk of explosion if the battery is
replaced with an incorrect type.
Dispose of used batteries according to the
manufacturer's instructions. Please recycle
when possible. Do not dispose as household
waste.
If you need to replace the battery, take it to your
nearest authorised LG Electronics service point
or dealer for assistance.
Always unplug the charger from the wall
socket after the phone is fully charged to save
unnecessary power consumption of the charger.
Actual battery life will depend on network
configuration, product settings, usage patterns,
battery and environmental conditions.
Make sure that no sharp-edged items such as
animal's teeth or nails, come into contact with
the battery. This could cause a fire.
