Maintenance
Normal use of the battery
It is recommended not to partially charge/discharge the battery several times in a row. Partial
charging/discharging affects the accuracy of the capacity measurement.
To recharge batteries
One battery inserted
To recharge the battery, connect external power to the DC input of the EXPLORER 710 while
the battery is inserted. For details on how to apply external power, see
Two batteries connected
You may connect an extra, external EXPLORER 710 battery for extra capacity. When external
power is applied to the EXPLORER 710, both batteries are charged as follows:
One battery is charged to 80%. Then the other battery is charged to 80%, and finally they are
both charged the last bit up to 100%, one at a time. This way both batteries are charged in the
shortest possible time.
The display and the web interface of the EXPLORER 710 show battery status such as which
battery is currently charging and the battery level.
Deeply discharged batteries (precharge mode)
Never leave the battery fully discharged for a longer period of time. If the battery is not to be
used for a shorter period of time (1 month), charge the battery to minimum 20 to 30% and
remove it from the EXPLORER 710. If the Battery is stored for more than a month, see
at the end of this section.
If a battery has not been used for a long time and has been discharged below its normal
operation range the EXPLORER 710 will not be able to apply the normal battery charging mode.
In this case an Alert is generated ("Internal/External battery low voltage") and the
EXPLORER 710 will use a precharging mode to recover the battery. The battery status in the
local display and the web interface will show "Precharging". No time estimate or battery
capacity will be indicated. Depending on how deeply discharged the battery is, the precharging
might process for up to 6 hours. After precharging, the EXPORER 710 will proceed with the
normal battery charging.
Note
When two batteries are connected (internal and external), only one at a time is active.
