Do not dispose of batteries in a fire !
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose
as household waste.
Note that a new battery's full performance is achieved only after two or three
complete charge and discharge cycles!
The battery can be charged and discharged hundreds of times but it will eventually
wear out. When the operating time (talk-time and standby time) is noticeably
shorter than normal, it is time to buy a new battery.
Use only batteries approved by the communicator manufacturer and recharge your
battery only with the chargers approved by the manufacturer. Unplug the charger
when not in use. Do not leave the battery connected to a charger for longer than
a week, since overcharging may shorten its lifetime. If left unused a fully charged
battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
Battery operation time is affected by the following: whether both the phone and
the communicator interface are on, radio signal strength, various phone settings,
and the length of the screen blanker period.
It is always recommended to keep a charged battery in the communicator. Keeping
the battery charged maximises the lifetime of the backup battery supplying power
to the real-time clock of the communicator. In case the backup battery is drained,
it will be automatically charged the next time a charged battery is reconnected to
the communicator.
Always close the device cover before removing the battery. Closing the cover will
save all data.
