Sharp 770SH User Manual page 156

• Do not touch the battery terminals. Batteries can
cause damage, injury or burns if a conductive
material touches exposed terminals. When the battery
is detached from the phone, use a cover made of
non-conductive material for keeping and carrying the
battery safely.
• Recommended temperature for using and storing
batteries is approximately 20°C.
• The batteries' performance is limited in low
temperatures, particularly below 0°C and the phone
may not work temporarily regardless of the amount
of remaining battery power.
• Exposing the phone to extreme temperatures will
shorten battery life.
• 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.
CAUTION
RISK OF EXPLOSION IF BATTERY IS REPLACED
BY AN INCORRECT TYPE,
DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS
See "Battery Disposal" on page 13.
