Care and Maintenance
 Battery Care
• Your device is powered by a rechargeable battery. When the power
is weak, please charge the battery. In order to extend the lifespan of
the battery, use all the battery's power before recharging.
• Unplug the charger from the electrical plug and the device when not
in use. Do not leave the battery connected to a charger more than a
week. Overcharging may shorten its lifespan.
• Extreme temperatures can affect the ability of your battery to
charge. Battery needs the fit temperature. If the surrounding
temperature is over 40°C, the battery cannot be charged.
• Use the battery only for its intended purpose. Never use any charger
or battery that is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object such as a coin, clip, or pen causes direct
connection of the positive (+) and negative (-) terminals of the battery.
(These look like metal strips on the battery.) Short-circuiting the
terminals may damage the battery or the connecting object.
• Leaving the battery in hot or cold places, such as in a closed car in
summer or a freezer in winter conditions, will reduce the capacity
and lifetime of the battery. Always try to keep the battery between
59°F and 77°F (15°C and 25°C). A hot or cold battery may not
function temporarily, even when the battery is fully charged.
• Battery performance is particularly limited in temperatures below
freezing.
• Do not dispose of batteries in a fire! Dispose of batteries according
to local regulations. Please recycle when possible. Cellphones are not
considered household waste.
