 If left unused, a fully charged battery will discharge itself over
time.
 Use only approved batteries; and recharge your battery only with
approved chargers. When a charger is not in use, disconnect it from
the power source. Do not leave the battery connected to a charger
for more than a week, since overcharging may shorten its life.
 Extreme temperatures will affect the charging capacity of your
battery: it may require cooling or warming first. Do not leave the
battery in hot or cold places, such as in a car in summer or winter
conditions, as you will reduce the capacity and lifetime of the
battery. Always try to keep the battery at room temperature. A
phone with a hot or cold battery may temporarily not work, even
when the battery is fully charged. Li-ion batteries are particularly
affected by temperatures below 0 °C (32 °F).
 Do not short-circuit the battery. Accidental short-circuiting can
occur when a metallic object (coin, clip or pen) causes a direct
connection between the + and - terminals of the battery (metal
strips on the back of the battery), for example when you carry a
spare battery in a pocket or bag. Short-circuiting the terminals may
damage the battery or the object causing the short-circuit.
 Dispose of used batteries in accordance with local regulations.
Always recycle. Do not dispose of batteries in a fire.
