Your docking device uses a lithium ion battery. The lithium ion cell battery
is a long-life battery, and it is very possible that you will never need to
replace it. However, should you need to replace it, perform the following
steps.
CAUTION: There is a danger of a new battery exploding if it is
incorrectly installed. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer’s instructions.
