21.5 Battery Charging Cycle
1.
The battery is charged at unit power up. The first two minutes after boot there
is a wait period before charging begins.
2.
In all charge cycles, battery is charge fully to 4.2V (4200mV).
3.
Charging mA should be 100mA.
4.
Maximum charge time is eight (8) hours. (In some low conditions, it can
theoretically take a battery eight (8) hours to fully charge.)
5.
When the battery voltage drops below 4000mV, a charging cycle is triggered.
6.
Again, battery is fully charged to 4.2V at a maximum of eight (8) hours.
NOTE: The controller will not charge the battery when it is outside. Its charging range is
typically -10°C to 35°C.
21.6 Battery Charging Status
Viewed in the System Menu under “View Battery Status”
Table 21.1
–
Charging State Table
Waiting
The charging system is waiting for voltages and temperatures to
stabilize.
Battery Charging
The battery is charging.
Battery Full
Shows at the end of a charge cycle. Remains in this state until the
battery is steadily discharging.
Battery Discharging
The battery is steadily discharging.
21.7 Battery Charging State
In the RCC, XL4, XL7, EXL6, EXLW and EXL10, the program downloaded from Cscape is not
battery backed. The program is stored in Flash memory RAM at the time of download. The
battery plays no part in program retention.
