Battery charging time depends on the remaining battery charge, the type of battery, and the charger
used. The battery can be charged and discharged hundreds of times, but it will gradually wear out.
When the operation time is noticeably shorter than normal, it is time to buy a new battery.
If left unused, a fully charged battery will discharge itself over time.
Use only approved batteries and battery chargers. Disconnect the charger from the power source
when it is not in use. Do not leave the battery connected to a charger for mor e 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 because the capacity and lifetime of the battery will be
reduced. Try to keep the battery at room temperature. A phone with a hot or cold battery may not work
temporarily, even when the battery is fully charged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object like a
coin, clip or pen causes a direct connection between the + and – terminals of the battery (metal strips
on the battery). For example, do not carry a spare battery in a pocket or bag where the battery may
contact metal objects. Short-circuiting the terminals may damage the battery or the object causing the
short-circuiting.
Dispose off used batteries in accordance with local regulations. Always recycle. Do not dispose off
batteries in a fire.
Do not charge the battery while using the phone.
