GRAUPNER mc-16 Programming Manual page 9

• Batteries must not get into the vicinity of babies or
small children. If a battery is swallowed, immediately
go to a doctor or emergency medical facility.
• Batteries must not be put in a microwave oven or
put under pressure. Smoke, fire and more can be
the consequences.
• Never dismantle a LiIo-/LiPo battery. Dismantling
a battery can cause internal short-circuits. Gas, fire,
explosions and other problems can result.
• The electrolyte and electrolytic vapors in LiIo-/LiPo
batteries are harmful. Absolutely avoid all direct
contact with electrolytes. If electrolytes come into
contact with skin, eyes or other body parts, immedi-
ately wash out or rinse out with generous amounts
of fresh water then be sure to consult a doctor.
• Batteries built into equipment must always be
removed from that equipment when it is not cur-
rently in use. Always switch off equipment after it is
used to prevent deep discharging. Always charge
batteries before it is too late. Store batteries on a
non-combustible, heat resistant, non-conducting
surface! Deep-discharged LiIo-/LiPo batteries are
defective and may no longer be used!
Storage
LiIo-/LiPo cells should have a 10 ... 20 %
charge capacity when stored. If cell voltage
drops below 3 V, then LiIo-/LiPo cells must
absolutely be recharged to a capacity of 10 ... 20 % of
full capacity. Otherwise, further deep-discharging of the
battery will make it useless during storage in a dis-
charged state.
Special notices for discharging LiIo-/LiPo batter-
ies from Graupner
• A continuous current rate of about 1 C does
not represent a major problem for Graup-
ner LiIo-/LiPo batteries. For larger currents,
please follow the catalog specifications. In any case,
observe the maximum current rating for the con-
nector system, see maximum discharge current on
the battery.
• Discharging below 2.5 V per cell damages cells per-
manently and is therefore to be avoided absolutely.
Short circuit conditions are to be avoided absolute-
ly. Permanent short circuits lead to destruction of
the battery, high temperatures and perhaps even
self-ignition may follow.
• During discharge, battery temperature must not
rise, in any case, to over +70 °C. Otherwise, bet-
ter cooling or a lower rate of discharge must be
introduced. The temperature can easily be checked
with the infrared thermometer, No. 1963. The bat-
tery must never be discharged via the transmitter's
charging socket. This socket is not suitable for this
purpose.
Other handling notices
• Never short-circuit the battery. A short-
circuit allows very high current to flow and
this heats up the cells. This will lead to loss
of electrolyte, the production of gases and perhaps
even explosions. In the vicinity of, or while handling,
Graupner LiIo-/LiPo batteries, avoid electrically con-
ducting surfaces because of the danger of creating
a short-circuit condition.
• Battery packs may only be connected in series or
parallel in exceptional cases as cell capacities and
charged state can differ too greatly. This is why the
battery packs we deliver are selected.
Handling connectors
• These connectors are not as robust as for
other batteries. This applies particularly to
the plus pole connector. The connections
can easily be broken off. Due to thermal transfer,
the connector tabs may not be soldered directly.
• The connections of LiLo / LiPo batteries are not as
robust as those of other batteries. This applies in
particular to the positive pole connection. The con-
nections can easily break off.
Cell connection
Direct soldering on battery cells is not permit-
ted.
The heat of direct soldering can damage bat-
tery components, such as separator or isolator.
Battery connections should only be made by industrial
spot welding. A professional repair made by the manu-
facturer or distributor is necessary to replace missing or
torn-off cables.
Replacing individual battery cells
The replacement of battery cells may only be
made by the manufacturer or distributor and
never by the user himself.
Damaged cell usage
Damaged cells may never be used or returned
to service.
Characteristics of damaged cells include: dam-
aged housing packing, deformed battery cells, electro-
lyte or leaking electrolyte. In these cases, further use of
the battery is not permissible.
Damaged or useless cells are hazardous waste items
and must be appropriately disposed.
General warning notices
Batteries must never be put in fire or burned.
Battery cells must not be submerged in liq-
uids, such as water, seawater or beverages.
Any contact with liquids, of whatever nature, is to be
avoided.
