• Never use any charger or battery which is damaged or worn out.
• Do not short circuit the battery. Accidental short circuiting can
occur when a metallic object (coin, clip, or pen) causes direct
connection of the + and - terminals of the battery (metal strips
on the back of the battery), for example when you carry a spare
battery in your pocket or purse. 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 winter conditions, will reduce the capacity and
lifetime of the battery. Always try to keep the battery between
59º F and 77º F (15º C and 25º C). A phone with a hot or cold
battery may temporarily not work, even when the battery is fully
charged. NiMH batteries’ performance is particularly limited in
temperatures below 14º F (-10º C). Li-Ion batteries’ performance
is particularly limited in temperatures below 32º F (0º C).
• Do not dispose of batteries in a fire!
• Dispose of used batteries in accordance with any local
regulations.
