General information Up to five batteries can be connected to the charger. Two batteries can be charged at the same time.
connected to the cigarette lighter socket of a vehicle can be used. The GKL221 is a very useful complement to all of your battery operated Leica Geosystems products.
With more than two batteries connected, the rest are charged in the order they were connected.
Beside charging, the charger can also discharge and refresh batteries.
We recommend starting up the product at this point, while continuing to read the Operating Instructions.

The Leica Geosystems GEB111 and GEB121 batteries have four contact surfaces, whereas
camcorder batteries made by third parties only have three. The charger can distinguish between these
two types of batteries and adjust the charging process accordingly.
Camcorder batteries with three contact surfaces must meet the following specifications to prevent
damage:
• Voltage: 6 V
• Type of battery: NiCd or NiMH
• Minimum capacity: NiCd 1500 mAh, NiMH 1800 mAh
• Compatible contacts in the correct sequence, i.e. "+, T, -" in one line.
Camcorder batteries that meet these specifications are monitored for temperature and charged with a
current of 1.6 A.
Inserting:
1. Insert the battery into the front edge of the
GDI222 battery bay.
2. Press it downwards until it clicks into place.
Removing:
• Pull up the back of the battery and remove it.
