8.2 The 7035 Battery
Warning: When a battery is removed from the terminal, a backup of the
system, application and any work in progress is maintained for
up to 10 minutes. A fresh battery must be installed within this
10 minute time frame. THIS BACKUP WILL NOT FUNCTION
UNLESS THE TERMINAL IS TURNED OFF BEFORE THE
BATTERY IS REMOVED. Removing the battery while the unit is
operating will result in a full reboot.
Even after the system backup has expired, the date and time are
maintained for at least 72 hours without a battery.
7035 Lithium-Ion batteries typically operate for nine to fifteen hours
1
after a charge.
These batteries do not require conditioning. Each battery pack tracks its own
capacity using an onscreen horizontal bar graph, referred to as the “battery gauge”.
The battery gauge displays the percentage of remaining battery power capacity –
0 to 100%, resolution 10% of nominal capacity. The operator is notified when the
battery capacity is low.
Typical battery life is 500 cycles or 2 years average use. A fast charge is completed
in 3.5 to 4 hours. The 7035 terminal will notify the user when the battery
performance has degraded to the point that it should be discarded.
