•

Quad Docking Station (Model #HU4004): can charge the battery of up to four hand-

helds inserted in the docking station while transferring data through an Ethernet 

connection.

•

Powered Cradle (Model # HU1010): can charge the hand-held with the battery installed 

in the hand-held.

It can take from 1.5 to 4 hours to charge a battery. The unit’s intelligent charging system pro-
tects the battery from over-charging by terminating the charge process when the battery is at 
maximum capacity.

Under normal operating conditions, fully charged batteries last for 8 hours. As lithium-ion 
batteries age, their capacity decreases gradually, and they are generally considered depleted 
after approximately 2 years of use (less than 60% of original capacity remaining). Keep in 
mind however that heavy usage or operating the 7545 at temperature extremes will shorten 
the battery life. 
Lithium-ion batteries do not require conditioning cycles and the 7545 battery system (in-
cluding chargers) requires no user interaction to maintain peak performance.
To maximize the run time of your batteries, consider the following:
•

The display backlight is the largest drain on the battery. Try to keep its brightness as low 

as possible. Adjusting the keyboard backlight also helps.

•

The hand-held is ‘event’ driven. That is, when the unit is not in use, it reverts to sleep 

mode (even when it appears to be running), saving battery power. Events include a key 

press, touchscreen taps and scan triggers. Power consumption is reduced if you avoid 
unnecessary events, and allow the unit to sleep as much as possible.
