Accordingly, the ventlla-
tion slots must
always be unobstructed.

Condilioning charge mode
E
NiCd cells are subject to self-discharge. With
older bat-
teries, the rate
of self-discharge of some of the cells may
be higher than that of others. As
conventional chargers
switch
off
when the first
cells
have reached
full charge,
the
other
partly
charged cells do not receive the full
charge. The
user becomes aware of
this
effect in the
form
of
inadequate
battery capacity.
This
effect can be eliminated by applying a conditioning
charge. During this
procedure,
the
charger supplies a
small
current over several
hours,
with
pauses
made in
order
to
avoid overheating the battery. Depending
on
its
condition, the llattery will take 7 to 10
hours t0 reach
full
charge.
The
conditioning charge begins when the
conditioning
mode button is
pressed
before insertion
of
the
battery
and released
approx. 3 seconds after the battery has
been
inserted.
The
yellow
LED lights while the
battery
is being charged in conditioning mode.
The battery
should be charged
in
conditioning mode no
more than
once a month. The conditioning
charge
is,
so to
speak, a
kind
of
"training"
for the battery. Just as
excessive training can be harmful to the human
body,
t00 frequent
use of conditioning charging mode can also
weaken
the battery.

Brforr a battery is
used
for the first
time, it must
be charged
for 24
hours
in normal
mode or for 1
0
hours
in conditioning mode in order to
permit
"forming"
of the
battery
cells.
-At
iow
temperatures: Battery
performance
drops at
low temperatures.
Store
batteries
at
r00m tempera-
ture when not in
use.
-At
high
temperatures: Do n0t store
batteries
where
they may be subjected t0 high temperatures
(e.9.
exposed
to
the sun, at a window, behind
a car
wind-
screen or on a radiator).
Never fully discharge
a battery. Change the battery as
s00n
as
its
0erformance
droos. The cells that reach
a
state of total discharge first will
otherwise be damaged
by the
current still being drawn from the other cells.
An
excepti0n
to this is the
BP 6-86 battery for the
TE 6-4
(this
battery is equipped with
an electronic deep
discharge
prevention
device).
