The unique battery solution in the Rugby has two independent battery
compartments that will accept various combinations of NiMH packs or
individual D-cell batteries (2).
The battery status is displayed on power-up and as small icons on the
main operating screen.
Install the NiMH batteries (1) as shown on the label of the pack.
Install individual D-cell batteries (2) as shown on the battery door cover.
The charge jack (3) is located on the laser above the locking knob of the

Charge time is approximately 4-5 hours.
The Rugby can also be run directly from a 12-volt source through the
charge jack.
Charging / First
Time Use
• The batteries must be charged prior to using it for the first time
because it is delivered with an energy content as low as possible.
• The permissible temperature range for charging is between +32°F to
+104°F (0°C to +40°C). For optimal charging we recommend charging
the batteries at a low ambient temperature of +32°F to +68°F (0°C
to +20°C) if possible.
• It is normal for the battery to become warm during charging. Using
the chargers recommended by Leica Geosystems, it is not possible to
charge the battery if the temperature is too high.
• For new batteries or batteries that have been stored for a long time
(> three months), it is effectual to make 3 - 5 charge/discharge cycle.
Operation/
Discharging
• The batteries can be operated from -4°F to +122°F (-20°C to +50°C).
• Low operating temperatures reduce the capacity that can be drawn;
very high operating temperatures reduce the service life of the battery.
