Operation - Ferm FPB-1800L Gebrauchsanweisung

GB
A short-circuit will cause a high current
to flow. This may result in overheating,
the danger of fire or explosion of the
battery block. This may damage the
battery block or the user may risk an
accident.
Therefore:
• Do not connect any cables to the poles of
the battery block.
• Take care that there are no metal objects
(nails, paper clips, coins, etc.) on the
contact surface of the battery block.
• Do not expose the battery block to water or
rain.
• A damaged battery block or one that can no
longer be charged must be disposed of as
special waste. Do not discard it with household
waste.
• Never throw the battery block onto a fire or into
water. This will risk explosion!

3. OPERATION

Only use the following chargers to
charge this battery:
• CDA1052: FPL-1800 Multi charger for
both CDA1051 (Lithium-Ion) and CDA1053
(NiMH)
• CDA1054: FPL-1800N LED charger for
CDA1053 (NiMH) only
Charging the battery
Fig. 1
• Place the battery stem into the matching cavity
on top of the charger.
• Make sure the battery stem is pressed fully into
the charger as far as it will go.
• Plug the charger into the electrical outlet.
Only charge NiMH batteries in ambient
temperatures between 5 ºC and 40 ºC.
Lithium-Ion batteries can be charged in
ambient temperatures between 0 ºC and
45 ºC.
Battery care Lithium-Ion.
In comparison to NiCd and NiMH cells, Lithium-Ion
cells have no memory effect due to intermedial
charging.

While NiCd and NiMH batteries need to be
discharged before charging, a Lithium-Ion block
does not need to completely discharged.
This battery block can be charged at any time
despite its current power level without losing much
of its original power and endurance.
Lithium-Ion cells can be stored for a long period
without losing much of their charge.
When the machine is not being used over a longer
period of time, it is best to store the battery in
charged condition.
Battery care NiMH.
Before using it for the first time, you should charge
it for approx. 1 - 2 hours so that it reaches full
capacity. The final capacity of the battery is
reached after 4 - 5 battery cycles.
Discharging the battery
Not only charging batteries is important,
discharging is of equal importance or
even greater importance.
When the battery is charged the tool has to be
used until you start noticing that the power of the
tool is diminishing and that the maximum rotational
speed is not reached.
The battery is almost discharged now. Only now
you can start charging the battery.
Charging the battery while it is still charged for say
one-third of capacity, the so-called 'memory effect'
can occur. Since during charging only the
discharged part of the battery capacity of the
battery is being charged now, the battery can start
crystallizing in the one-third that is still charged.
This part of the battery capacity can never be used
afterwards.
Do not discharge the battery to the minimum. As
soon as you notice that the power or the maximum
rotational speed is diminishing, you have to charge
the battery. When you proceed using the tool and
the battery becomes fully discharged, the so-
called 'switch of poles effect' can occur. The
polarity of the battery poles will be switched: the '+'
will become '-' and the '-' will become the '+'. Once
this has occurred the polarity will remain switched
during loading and this will damage the battery
irreparable.
