IMPORTANT BATTERY TIPS
• Use only the supplied charger and use only batteries
designed for this phone.
• You can purchase additional standard or extended
capacity batteries through your local RadioShack store.
• When you are not using the charger, disconnect it from
power. Do not leave the battery connected to the charger
and AC power for more than 24 hours, since overcharg-
ing could shorten the battery’s life.
• When the battery is not in use, store it uncharged in a
cool and dark place.
• The battery is a sealed unit with no serviceable parts. Do
not try to open the case.
• For the best results, be sure the battery is at or near
room temperature when you charge it.
• A battery can be charged and discharged hundreds of
times, but it eventually wears out. When the operating
time (talk time and standby time) is noticeably shorter
than normal, get a new battery and recycle or properly
dispose of the old one.
• Do not dispose of batteries in a fire.
• Never use any charger or battery that is damaged or
worn out.
