1 System Description
Description The Leica Geosystems GKL221 is an intelligent charger with advanced charging technology. It is
designed to charge all Leica batteries. As power supply, the mains as well as GDC221 vehicle dapter
connected to the cigarette lighter socket of a vehicle can be used. The GKL221 is a very useful comple-
ment to all of your battery operated Leica Geosystems products.
General information Up to five batteries can be connected to the charger. Two batteries can be charged at the same time.
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.

Pull the plug from the mains socket and from the vehicle's power socket, if the charger will not be used
for a long period.
Only use the vehicle adapter for power supply from a vehicle. If the power supply comes from other
sources, such as transformers, malfunctions could occur. Refer to section "5 Technical Data" for infor-
mation on voltage and rated power.
Check older vehicles and makes sure that the + pole is on the middle contact surface of the cigarette
lighter socket. Should the polarity be wrong, then the fuse in the charger or the fuse in the vehicle
adapter has to be changed. The fuse in the charger has to be changed by an authorised Leica Geosys-
tems service workshop. The fuse in the vehicle adapter has to be changed as described in the manual
of the adapter.
Function check After the adapter is connected to the mains or to the vehicle's battery circuit, the red, yellow and green
function indicators light up once, the capacity and error indicators light up red and green. This is a func-
tion check.
If no battery was inserted, then only the green function indicator will light up.
If the status indicator and the three capacity and error indicators light up and remain red, then a defect
was detected. Refer to section "2.6 Indicators" for additional information.

NiCd and NiMH batteries
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.

2.5 Charging the Battery
Procedure
Set the charging sequence The GKL221 charger can charge two batteries simultaneously.
When more than one battery is connected to the charger, the one connected first is charged first.
Always connect the more urgently needed battery first.
Priorities Batteries are charged at the external battery connection without interrupting a charging process already
begun.
Retaining the full charge When the battery is fully charged, it may remain connected. NiCd and NiMH batteries are charged in
turns to retain their full charge. In this way, the intrinsic self-discharging is compensated and the battery
is always fully charged and ready for use. Refer to section "Charging modes" for more information.
Step Description
1. Insert the battery adapter.
2. Connect the charger to the power supply, the green function indicator lights up.
3. Insert the battery. The yellow status indicator flashes to indicate that the battery has been
recognized.
4. Make sure the green status indicator remains on.
The battery is now being charged. Refer to section "2.6 Indicators Lamps", if after
connecting the battery a different status indicator lights up.
Check the status indicator after about one minute.
5. The battery has been completely charged when the green status indicator starts to flash.
Refer to section "5 Technical Data", for information on the charging times.
6. The battery may be removed or remain connected to ensure it is fully charged when
needed. Refer to section "Charging modes" for more information.

Refreshing the battery The refresh function totally discharges the battery and then puts it on quick charge.
Step Description
1. Connect the charger to the power supply.
2. Insert the battery. The yellow status indicator flashes to indicate that the battery has been
recognized.
3. Press the selection button for more than three seconds to start the process of discharging
the battery. Discharging is indicated by the red status indicator flashing.
Discharging may take a long time for large capacity batteries. To keep discharge
times short, only use this function with batteries that are empty or low on charge.
4. When the battery has been discharged, it is put on quick charge. The status indicator lights
up green.
5. The battery has been completely charged when the green status indicator starts to flash.
We recommend refreshing NiCd and NiMH batteries two to three times when their capacity
starts to sink noticeably.
For Li-Ion batteries, a single discharging and charging cycle is sufficient. We recommend
carrying out the process when the battery capacity indicated on the charger or on a Leica
Geosystems product deviates significantly from the actual battery capacity available.

Error indicators
If the charger indicates an error when the battery is connected:
• Connect a different battery to check if the fault lies with the battery or the charger.
• If the problem persists, contact an authorised Leica Geosystems service workshop.
In case of error, please also check:
• If there is power coming from the mains or vehicle battery power circuit.
• If the cables are all correctly connected and no obvious faults can be detected.
• If the function indicator is lit on the optionally connected vehicle adapter.
LEDs Meaning Measures to take
The battery is too cold or overheated. Refer to section "Temperature range" for
additional information.
The battery is defective. Use a different battery.
Faulty contact on the battery or the
battery adapter.
Check the contacts.
Hardware error in the charger. Contact an authorised Leica Geosys-
tems service workshop.

2.7 Tips
Tips • To charge batteries to their full capacity, new NiCd and NiMH batteries should be fully discharged
and charged three to five times.
• Let the batteries in the instrument discharge as much as possible. It prevents the so-called "memory
effect" with NiCd batteries.
• When using the vehicle adapter, always keep the motor running while charging the batteries.
Avoid sudden ambient temperature changes while charging the batteries (e.g. do not let the sun shine
directly on the batteries or on the charger). Sudden ambient temperature changes may cause the
charging process to end prematurely without having fully charged the batteries.
