Introduction
The reliable supply of power to surveying equipment
forms one of the most important preconditions for all
surveying tasks in the field. It is a basic precondition for the
function of the equipment and a key factor for reliable,
malfunction-free operation in all environmental conditions.
Chargers
1.1 Charging technology
Leica Geosystems currently provides quick chargers as
a matter of preference (accelerated charging). These
charge the batteries in a correspondingly short time. They
ensure, thanks to the latest charging technology,
appropriate charging and therefore, the long life of the
batteries. Our chargers are divided into two product lines.
The Professional Series for the highest of demands and
functionality, and the Basic Series as a simple, low
cost alternative.
For batteries with 5-pin charging sockets, a simple, low cost
normal charger with reduced functionality is still offered.
1.2 Professional Charging Station
GKL221
The GKL221 is an intelligent charging station with
advanced charging technology. It is suitable for charging
all Leica Geosystems batteries and ensures the optimal
battery operation with your equipment.
Supply
The GKL221 can be connected to the mains electricity
supply with an input voltage range from 100 to 240 V AC,
using the country specific power cable. With the optional
GDC221 car adapter, the charging station can be connected
to the battery circuit of a vehicle.
Battery – Identification
The microprocessor controlled charging station recognises
the type of battery connected and derives the charging
parameters such as time and current. The batteries are
optimally and appropriately charged. This guarantees the
maximum possible service life. The charging station can
recognise and charge cells of the NiCd, NiMH and Li-Ion
types. Up to five batteries can be connected to the charger
simultaneously. Two batteries are charged at the same time
and the rest are charged in the order they were connected.
For batteries to have a long service life, retain their
performance and operate without malfunctions, they must
be correctly maintained, stored, charged and discharged.
Incorrect handling of batteries and chargers can lead to
malfunctions or premature loss of capacity of the batteries.
This product information summarises the most important
and useful information on the chargers and batteries for
Leica Geosystems surveying instruments and surveying
systems.

Charging times
Trickle charging
The charging time depends primarily on the maximum charging current, the battery capacity and the charge
state of the batteries when connected. Charging time of
discharged batteries at +20 °C (+68 °F):
•NiCd batteries:
max 2200 mAh 1.0 to 1.5 h
max 7200 mAh 2.5 to 4.0 h
•NiMH batteries:
max 2200 mAh 1.5 to 2.0 h
max 4900 mAh 2.0 to 2.5 h
max 10000 mAh 2.5 to 5.5 h
•Li-Ion batteries:
max 4600 mAh 2.5 to 3.5 h
If fully charged batteries remain connected to the charging
station, trickle charging is performed automatically. This
compensates for the self-discharge of the batteries that
occurs for technical reasons. The batteries are thus always
available with full capacity. The trickle charging feature only
activates for NiCd and NiMH batteries as Li-Ion batteries
only have a very small discharge when not in use.
Refresh function
If the capacity of a NiCd or NiMH battery drops noticeably, it
is recommended to subject the battery to the refresh
function 2 to 3 times. The refresh function comprises a full
discharge of the battery with subsequent quick charging.
Further information can be found in the user manual of the
GKL221. The memory effect of batteries is explained in
Section 2.8.
At ambient temperatures above +20 °C (+68 °F) the
charging time for NiCd and NiMH batteries can increase by
up to 1 hour. (For recommended charging temperature
range see Section 2.4.) As the temperature of the battery
increases towards the end of charging, the efficiency
of the storage of the charge drops. For example with the
GEB121, in the first 90 minutes approximetely 80% of
the battery is charged and a further 60 minutes is required
for the remaining 20%.
A temperature control mode is built into the GKL221
charging station. This temperature control mode is activated
as soon as the battery becomes warm. In temperature control mode, the charging current is switched off until the temperature of the battery has dropped back to a specific value.
Charging is then continued with reduced charging current.
The switch off in temperature control mode of the charging
current is not noticeable to the user as the indicator remains
green (charge). The temperature control mode is also
activated if the ambient temperature is too high.

1.3 Normal Charger GKL22
The GKL22 is a simple, low cost normal charger (14-hour
charger) for charging NiCd and NiMH batteries. It is
available in the GKL22 (EU) and GKL22-1 (US) mains supply
versions.
Supply
The GKL211 can be connected to the mains electricity
supply or to the battery circuit of a vehicle. A country
specific AC/DC adapter and a car adapter cable are included
with the charger.
Battery identification
The type of battery connected is recognised by an
identification chip and derives the charging parameters such
as time and current. The batteries are optimally and appropriately charged which guarantees the maximum possible
service life.
Charging times
Charging times and change in capacity during charging are
similar to that for the GKL221.
Trickle charging and refresh function
Battery – Identification
The GKL22 has no facility for the recognition of the
battery type and charges all batteries with the same
charging current. All Leica Geosystems batteries with 5-pin
charging socket can be charged except the GEB171.
Charging time
The charging time is 14 hours at a current of 200mA.
This charger has no trickle charge or battery refresh
function.
1.5 Basic Series Charger GKL112
The GKL112 is a simple, low cost quick charger for charging
NiCd and NiMH batteries. It is used for the Leica GEB111 and
GEB121 batteries. The specifications are similiar to the
GKL211 charger as detailed above.
Trickle charging and refresh function
This charger has no trickle charge or battery refresh
function.
Trickle charging
The charger has a trickle charge feature. This ensures that
the battery is always fully charged and ready for use.
1.6 Safety/precautionary measures

Batteries
2.2 Condition when delivered
NiCd
2.1 Cell types
For safety reasons, the batteries are only dispatched from
the factory in a discharged state.
In this way, in the case of misuse or damage to the battery,
hazardous conditions or physical damage caused by a large
amount of stored energy are prevented.
Leica Geosystems currently uses nickel-cadmium (NiCd),
nickel-metal hydride (NiMH) and Lithium Ion (Li-Ion) cells.
The cell type is marked on the battery.
NiCd
NiMH
The NiCd cell is a proven, mature type of cell requiring little
maintenance. Suitable for high charging and discharging
currents and problem-free usage down to –20 °C (–4 °F).
For safety reasons, damage free storage and shipment, the
batteries are dispatched with a minimal quantity of energy.
NiMH batteries must not be stored in a discharged state. The
batteries should therefore be fully charged as soon as possible once received.
NiMH
NiMH cells have a higher internal resistance than NiCd
cells and are therefore not suitable for such high charging
and discharging currents, or low temperatures as NiCd cells.
The voltage of the battery collapses rapidly at negative temperatures and high current loading. This can result in the
activation of the deep discharge protection fitted in all Leica
Geosystems batteries. This means that the full capacity of
the NiMH batteries cannot be drawn at low temperatures.
Leica Geosystems only uses NiMH cells that provide
problem-free operation when supplying the current drawn
by all Leica equipment, even at –20 °C (–4 °F).
Li-Ion
For safety reasons, damage free storage and shipment the
batteries are dispatched with a minimal quantity of energy.
2.3 Charging the batteries
New and stored batteries
Li-Ion
Li-Ion cells have a high energy density. This minimises
battery size and weight. It is a low maintenance battery; there is no memory effect and no scheduled cycling is required
to prolong the battery’s life. In addition, the self-discharge is
less than half that compared to NiCd.
The batteries have a lifetime of about 3 years from
manufacture. This is caused by internal oxidation which is
hastened at high temperatures. The Li-Ion batteries
supplied by Leica Geosystems have a protection circuit to
maintain safe operation, limits the peak voltage of each
cell during charge and prevents the cell voltage from
dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes.
New NiCd and NiMH batteries reach their maximum
capacity only after a few charging and discharging cycles.
The batteries should be fully discharged and charged
three to five times. NiMH batteries that have been stored
and not used for an extended period (more than a month)
should be refreshed simularly. For Li-Ion batteries, a single
discharging and charging cycle is sufficient.
The easiest way to perform this cycling is by using the
GKL221 Charging Station which has a discharge function. Alternatively, the batteries can be charged and then placed in
the related survey equipment during normal use and discharged until the equipment switches off.
Batteries in regular use
After use the battery can be placed in the charger until
fully charged (the green light flashes). The charging time depends on the battery capacity and temperature.
An indication of charging times is shown on Page 3.

2.4 Charging temperature
2.7 Shipment
The charging temperature (ambient temperature) has a
significant impact on the life of the batteries. Charging at
high temperature can cause loss of capacity. These losses in
capacity are irreversible. Even with several charging and
discharging cycles, the original capacity can no longer be obtained.
For optimal charging, we recommend that the batteries
be charged at ambient temperatures as low as possible
(+10 °C to +20 °C / +50 °F to +68 °F). The permitted temperature range in which charging can still be performed is
between 0 °C and +35 °C (+32 °F and +95 °F). Due to a
temperature control mode built into the GKL221, GKL211
and GKL112, charging at temperatures that may cause
damage to the batteries is not possible.
To prevent hazardous conditions or physical damage
(fire, chemical or toxic hazards) batteries must be shipped
discharged. The regulations relating to the shipment of
batteries must be adhered to.
2.5 Useful capacity
The temperature has a particularly significant effect on
the useful capacity of a battery. In accordance with the
operating range for the surveying instruments, the batteries
can be operated from –20 °C to +55 °C (–4 °F to +131 °F).
With reducing temperature the useful capacity drops
rapidly. Continuous use in the upper temperature range
(> +45 °C / +131 °F) shortens the life of the battery.
2.6 Storage
Leica Geosystems batteries can be stored at –40 °C to
+55 °C (–40 °F to +131 °F). Do not store batteries inside the
surveying instrument. After storage, charge the battery
fully before use.
NiCd
NiCd batteries can be stored for an unlimited period in any
state of charge.
NiMH
NiMH batteries must always be stored fully charged and
recharged after 180 days at the latest. High temperatures
and high atmospheric humidity accelerate self-discharging.
We recommend storage in the range from 0 °C to +20 °C
(+32 °F to +68 °F) in a dry environment. If NiMH batteries
are stored in the discharged state for an extended period
irreversible damage can be caused.
2.8 Memory effect
The «Memory Effect» occurs if the same charging and discharging (partial discharge) conditions are continuously applied
to a battery. The battery then no longer provides the full capacity. The operating time per battery charge reduces. If the
capacity of the battery drops noticeably, it is recommended
to subject the battery to the refresh function 2 to 3 times
(see Section 2.9). The memory effect occurs particularly with
NiCd batteries. With NiMH batteries the memory effect is not
so pronounced. Li-Ion batteries are not influenced by the
memory effect.
2.9 Battery refresh function
If the capacity of a NiCd or NiMH battery drops noticeably,
the battery can be refreshed using two to three full charge
and discharge cycles.
The GKL221 Charging Station has a discharging and
charging function for refreshing batteries. Since GKL112 and
GKL211 do not have a discharge function the batteries are
to be discharged in the instrument (i.e. operate until
the instrument switches off).
2.10 Defective batteries
Even in the case of correct handling, it may occur that a
statistically small number of batteries fail prematurely. A possibly defective cell must never be replaced in a battery pack.
The cells in a battery pack are all from the same
manufacturing batch and thus have the same manufacturing
tolerances. If new and old cells are mixed, the weaker (old)
cells in the battery pack are more heavily loaded and further
failures inevitable. For this reason, the entire battery pack is
always replaced in Leica Geosystems service centres.
The Li-Ion and camcorder type batteries are in sealed
housings and the cells cannot be replaced.
Li-Ion
Li-Ion batteries start to deteriorate from manufacture. To
reduce the aging effect, store the battery in a cool place
at 10%–50% state-of-charge. Li-Ion batteries do not require
regular charging while in storage.
6
2.11 Life
Malfunctions
The life of batteries is primarily defined by the following
factors:
• Electrical loading
• Charging method
• Temperatures on charging, discharging and storage
• Quality of the cells
Losses in capacity caused by incorrect charging are
practically excluded with the Leica Geosystems chargers
which have special switch off criteria to protect the battery.
Reduction in battery capacity is normally due to age.
However it can also be the result of storage at excessively
low or high temperatures (see Section 2.6). The suppliers
who provide batteries to Leica Geosystems are among the
leading manufacturers of batteries and guarantee good quality.
To prevent malfunctions, a «basic suppresser» is
integrated into the adapter. With the engine running or
on the switch on of other loads (i.e. electric windows)
there are often large interference spikes in vehicle electrical
systems. These cannot be sufficiently attenuated by the
basic suppresser. If vehicle electrical systems are used
to supply power, it is imperative that the engine and other
loads are switched off to prevent malfunctions.
Mains supply
On the usage of a 12 V DC source supplied from the mains,
the corresponding information and notes from the manufacturer on the permitted use and safety are to be observed.
4.
2.12 Protecting the
environment/disposal
For reasons of environmental protection and safety, used
or defective batteries must not be thrown away. They must
be correctly disposed of in a discharged state. Follow the national regulations on disposal.
2.13 Safety/precautionary
measures
For the safe usage of batteries, please refer to the section
on safety in the User Manual supplied with the products.
3.
Supply from other 12 V DC
sources
Customer benefits on the
usage of Leica Geosystems
accessories
The batteries available from Leica Geosystems are of
the highest quality in respect of temperature tolerance,
recharging capability, operating time and cycle behaviour.
If the recommendations given in this document are followed
and Leica Geosystems chargers are used, there exist the following significant advantages for the user:
• Long battery life.
• Reliable supply of power in the field.
• Batteries and chargers compatibly matched.
• Quick charging of batteries.
• Prevention of the memory effect in batteries.
• Trickle charging after completion of charging.
• Microprocessor controlled and monitored charging.
• Discharging with regeneration charging of the batteries
• using GKL221 Charging Station.
GEV71 Cable
For the supply of power to Leica Geosystems equipment
from external 12 V DC networks (i.e. vehicle electrical
systems) the GEV71 car battery connecting cable must be
used. This is connected to the standard battery cable used
for Leica Geosystems external batteries.
Protection
The GEV71 cable protects the instrument from damage due
to pole reversal, voltage spikes occurring over a limited
period and electrostatic discharges. The cable also provides
a deep discharge protection to the connected battery.
