Radio Shack CT-354 - Manual (Page 9)

• When the battery is not in use, store it
uncharged in a cool and dark place.
• The battery is a sealed unit with no service-
able parts. Do not try to open the case.
• You can purchase additional standard or
extended capacity batteries through your local
RadioShack store.
• A battery can be charged and discharged hun-
dreds of times, but it eventually wears out.
When the operating time (talk time and
standby time) is noticeably shorter than nor-
mal, it is time to get a new battery.
• Leaving the battery in a hot or cold place, such
as in a closed car in the summer or winter,
reduces the battery’s capacity and life. Always
try to keep the battery between 59° and 77°F
(15° and 25°C). A phone with a too hot or too
cold battery might not work, even when the
battery is fully charged, until the battery
returns to a normal temperature. Nickel metal
hydride (NiMH) batteries are particularly lim-
ited in temperatures below 14°F (–10°C).
• Use the battery only for its intended purpose.
• Never use any charger or battery that is dam-
aged or worn out.
