Chapter 3: Getting To Know Your 7535 G2

Monitoring The Battery And Maximizing Run Time

Psion Teklogix 7535 G2 Hand-Held Computer User Manual 41

• 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.

3.1.4 Monitoring The Battery And Maximizing Run Time

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 7535 G2 at temperature extremes will

shorten the battery life.

Lithium-ion batteries do not require conditioning cycles and the 7535 G2 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.

Note: Refer to “Monitoring The Battery And Maximizing Run Time” on page 41 for addi-

tional information about the battery.

Important: To avoid damaging the battery, chargers will not begin the charge process

until the battery temperature is between 0° C (32° F) and 39° C (102° F). If

the battery is too hot or cold, the battery status LED flashes yellow and the

charge is suspended. Refer to Table 3.1: “Charge LEDs” on page 53 for

details.
