Using the charger for the first time
Connect the charger to a easily accessible mains
socket near to the charger, when using the 100 - 240
V AC power input, or to a car battery using the 12
V DC power input, or to a 11 - 15 V DC mains PSU
with a current rating of at least 5 A.
Stand-by mode
As soon as the Ultramat 8 is connected to a suitable
power source, all three LEDs will flash one time and
then the blue and red LEDs start flashing simultane-
ously at three-second intervals.
Caution: if you press the NiMH / NiCd or LiPo button
while the charger is in Charge mode or Error mode,
the Ultramat 8 immediately reverts to Stand-by
mode.
Charge mode
LiPo batteries:
Set the current select switch to the charge current
appropriate to the LiPo pack you wish to charge.
Now select a suitable genuine GRAUPNER Lithium-
Polymer battery pack consisting of up to four cells,
and connect the two pole power wire to the 4mm
banana ‚BATTERY' output of the Ultramat 8.
If the battery does have a balancer connector,
connect the balancer connector to the balancer
connector input of the charger.
Make sure for the right polarity.
From right handed to left side:
Pin 1 (GND): Ground = battery -,
Pin 2 (1): + cell 1, Pin 3 (2): + cell 2, Pin 4 (3): + cell
3, Pin 5 (4): + cell 4
The green LED on does confirm the right balancer
connection and function.

LiPo-button
To charge a Lithium-Polymer battery pack consisting
of one to three cells, simply press the LiPo button
briefly once you have connected the battery to
the charger. The blue LiPo LED now lights up to
confirm that charging is taking place. Pressing the
LiPo button again interrupts the charge process. If
you do this, the Ultramat 8 switches immediately to
Stand-by mode.
The Ultramat 8 has been developed to provide a
method of charging sensitive Lithium-Polymer cells
which is as simple and safe as possible.
This means that the Ultramat 8 starts charging at a
fairly low current, and carries out an assessment of
the battery before automatically raising the charge
current. When the pack approaches the maximum
charge capacity, the unit reduces the charge current,
again completely automatically.
This charge process always charges the battery to
100% capacity in a way which avoids cell damage.
"Battery charged" mode
As soon as the battery has reached 100% of its
capacity, the Ultramat 8 automatically switches the
process off.
This is indicated by the blue LiPo LED flashing at
0.5 second intervals. At the same time an audible
signal sounds at one-second intervals for about
fifteen seconds.
The green LED will be off, if the battery is completely
balanced.
It is completely normal for the battery pack to feel
cool or even completely cold at the end of the
charge process, as the Ultramat 6 automatically
reduces the charge current towards the end of the
charge process.
Disconnect the charged battery and press the LiPo
button in order to switch the Ultramat 8 to Standby
mode. The blue and red LEDs now flash at three-
second intervals to indicate Stand-by mode.

Charge mode
NiMH-/NiCd- batteries:
Set the Delta Peak cut-off voltage select switch to
the value you prefer (e.g. 5 mV for NiMH or 20 mV
for NiCd), then set the appropriate charge current on
the current select switch.
Now select a suitable genuine GRAUPNER NiMH
/ NiCd battery consisting of up to ten cells, and
connect it to the output of the Ultramat 8. To charge
a NiMH / NiCd battery consisting of one to eight
The red NiMH / NiCd LED now lights up to confirm
that charging is in progress.
Pressing the NiMH / NiCd button again interrupts
the charge process. If you do this, the Ultramat 8
switches immediately to Stand-by mode.
The Ultramat 8 has been developed to provide a
method of charging NiMH and NiCd batteries which
is as simple and safe as possible.
This means that the Ultramat 6 starts charging at a
fairly low current, and carries out an assessment of
the battery before automatically raising the charge
current. When the pack approaches the maximum
charge capacity, the unit reduces the charge current,
again completely automatically. This charge process
always charges the battery to 100% capacity in a
way which avoids cell damage.
"Battery charged" mode
As soon as the battery reaches the set Delta-Peak
cut-off voltage / cell, the Ultramat 8 automatically
switches the process off.
This is indicated by the red NiMH / NiCd LED
flashing at 0.5 second intervals. At the same time
an audible signal sounds at one-second intervals for
about fifteen seconds.
It is completely normal for the battery pack to feel
warm (approx. 30 - 45°C) towards or after the end of
the charge process.
Disconnect the charged battery and press the NiMH
/ NiCd button in order to switch the Ultramat 6 to
Standby mode. The blue and red LEDs now flash at
five-second intervals to indicate Stand-by mode.
Disconnect the input of the charger, if not another
battery will be charged.
Notes:
• Warm batteries offer much higher performance
than cold ones, so don't be surprised if your batte-
ries don't seem so effective in the Winter.
• Overcharging and deep-discharging batteries leads
to irreparable damage to the cells, and permanently
reduces their maximum performance and effective
capacity.
Error mode
The ULTRAMAT 8 incorporates a range of protective
systems designed to avoid damage to the battery
and the charger.
For example, the Ultramat 8 is protected against
short-circuit at the input and the charge output.
If a fault should arise, the Ultramat 8 automati-
cally switches to Error mode.
This mode is indicated by both LEDs (blue
and red) flashing at three-second intervals. At
the same time an audible signal sounds at 0.5
second intervals.
The type of error is indicated by the number of
times the LEDs flash before a brief pause; the
audible signal continues to sound during the
intervals.
