Charging the batteries
Your phone comes with a rechargeable internal lithium ion (LiIon) battery,
which you do not need to remove to charge.
This LiIon battery is partially charged when you receive the phone. Fully
charge the battery as soon as you can to maximize talk time. If the charge
falls too low, the phone turns off without saving any functions in progress.
