Introduction
The GKL 122 is an intelligent charger
employing advanced charging
technology. It is suitable for charging
all Leica batteries not only from the
mains supply but also in a vehicle,
and represents an optimal
complement to your battery-operated
Leica Geosystems instrument (see
"View of system").
The only difference between the
GKL122, GKL122-1, GKL122-3 and
GKL122-4 chargers lies in the mains
cable. Only the designation GKL122
will be used in the following.
Up to four batteries may be
connected to the charger. The type of
cell technology used in the battery
(NiCd, NiMH, LiIon, lead) is
immaterial because the
microprocessor-controlled charger
recognises the type of battery which
has been connected, and its state of
charge, and deduces from this
charging parameters such as
charging current and charging
algorithm.
The batteries are charged as quickly
and reliably as possible one after the
other (sequentially) in the order they
are connected, and so hold their
charge for a long time.
The charging time depends primarily
on the maximum charging current,
the battery capacity and its state of
charge on insertion / connection (see
"Technical Data".
Only Leica batteries with 5-pin
charger plugs or Leica standard
batteries in "camcorder format" with
four contacts and integral
temperature sensor and battery
recognition are charged quickly.
Older Leica batteries with 2-pin
charger plugs can only be connected
to the charger by using a suitable
adapter cable. They are charged in
about 14 hours (normal charging).
Additionally, there is a refresher
function available which first fully
discharges the battery which is
connected and then carries out quick
charging. This is particularly
important for NiCd batteries because
of the so-called "memory effect" (see
"Refreshing Batteries"). This function
can only be used for batteries which
can also be quickly charged.
The charger is only suitable
for charging and discharging
original Leica batteries as well as
some camcorder batteries (see
"Connecting Batteries").
