You can also attach the battery charger to a tripod, a belt, or an RTK pole to provide external power to the base
station or rover.
Before using the Sokkia Atlas, fully charge the batteries for maximum operating time.
Battery Charging Temperatures
Charge the batteries only in temperatures between 32
o
F (0
o
C) and 113
o
F (45
o
C).
An optimal charging temperature is between 50
o
F (10
o
C) and 77
o
F (25
o
C). If possible, charge
the batteries within this temperature range.
Charging Procedure
There are two ways to charge the receiver’s detachable batteries:
•
while they are attached to the receiver
•
while they are attached to the charging cradle
If the batteries are attached to the receiver or to the charging cradle, in approximately six hours the batteries
will be simultaneously fully charged.
The Li-Ion batteries used in the battery packs should run at no less than 80% capacity after 500 charging cycles.
You do not need to drain these batteries before recharging.
To charge the batteries using the power supply unit:
1. Plug the receiver-to-SAE power cable into the
receiver’s power input port.
2. Connect the receiver-to-SAE power cable and
the power supply-to-outlet cable to the AC
adapter.
3. Plug the power supply-to-outlet cable into an
available outlet. The batteries are fully charged
after approximately 6 hours.
To charge the batteries using the charging
cradle:
1. Remove the batteries from the receiver and
insert them into the charging cradle.
2. Connect the power cable to the power supply
unit.
3. Connect the SAE connectors on the power
adapter cable and power supply unit.
4. Connect the power adapter cable to one of the
ports on the charging cradle (either port will
charge both/either battery).

5. Plug the power supply to an available outlet. The batteries are fully charged after approximately 6 hours.
Leaving the Batteries on Charge
The batteries can be safely left in the receiver or the charging cradle once charging is complete. Doing so will
not overcharge or damage the batteries.
The batteries can also be attached/detached to/from the receiver or charging cradle at any time without
harming the batteries, the receiver, or the cradle. When returning the batteries to the receiver or cradle,
charging is automatically resumed.
