•
Batteries must not get into the vicinity of babies or
small children. If a battery is swallowed, immedi-
ately 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, im-
mediately 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
discharged state.
Special notices for discharging LiIo-/LiPo
batteries from Graupner
•
A continuous current rate of about 1 C
does not represent a major problem for
Graupner LiIo-/LiPo batteries. For larger
currents, please follow the catalog specifications.
In any case, observe the maximum current rating
for the connector system, see maximum discharge
current on the battery.
•
Discharging below 2.5 V per cell damages cells
permanently and is therefore to be avoided abso-
lutely.
Short circuit conditions are to be avoided
absolutely. 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, better
cooling or a lower rate of discharge must be in-
troduced. 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 conducting 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
connections can easily break off.
Cell connection
Direct soldering on battery cells is not
permitted.
The heat of direct soldering can damage
battery components, such as separator or isolator.
Battery connections should only be made by
industrial spot welding. A professional repair made
by the manufacturer 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:
damaged housing packing, deformed battery cells,
electrolyte 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.
