Battery
• The battery is a consumable item, and battery life varies with
usage conditions. Typical battery life is approximately one year or
about 500 charge cycles. As the battery reaches the end of its life,
the amount of time it can be used becomes dramatically shorter
and repeated charging does not restore its performance. When
this occurs, the battery should be replaced with a new one.
