Power Input / Main Battery; Backup Battery - Honeywell Marathon Reference Manual

Power Input / Main Battery

The Marathon is powered by a main battery (Lithium Ion rechargeable 2200 mAh) concealed inside the Marathon case, that
provides 3.5 hours of operation without a recharge. The main battery can be recharged using external power sources, such as
an indoor AC/DC adapter connected directly to the Marathon. The main battery remains concealed in the Marathon while
charging.
The main battery will also recharge when the Marathon is docked in a powered desktop dock or vehicle dock. With an attached
fully charged extended battery, Marathon battery life is increased to 6 or 10 hours based on the extended battery selected.
The main battery and an attached extended battery are recharged whenever the Marathon is:
connected to an AC power adapter
l
placed in a powered desktop dock
l
placed in a powered vehicle dock.
l
When AC power is disconnected from a Marathon with an attached extended battery, operating power is drawn from the
external battery until it is depleted, then from the main battery.

Backup Battery

The Marathon has a permanent lithium battery installed to maintain time, date and BIOS setup information. The backup battery
is not user serviceable and should last five years with normal use before it requires replacement. The lithium backup battery
should only be exchanged by authorized service personnel.
