SAFETY PRECAUTIONS LITHIUM BATTERIES

1. General
Lithium batteries (accumulators) are energy storage devices
with a high energy density and can present risks. For this reason,
particular care is needed when charging, discharging, storing and
handling.
Read these instructions very carefully before first using the
battery. Do not fail to take note of the warning notices and
instructions for use.
Misuse can lead to risks such as explosion, overheating or fire.
Failure to observe the instructions for use leads to early failure and
other defects.
The instructions should therefore be kept in a safe place and it
is essential that they are handed over to the second user if the
batteries are passed on.
2. Warning notices
• Avoid short-circuits. A short-circuit may well destroy the
product. Cables and connections must be well insulated.
• It is essential when connecting the battery to ensure that the
polarity is correct.
• Original plug connectors and cables may not be cut off or
changed - if need be, use an adapter cable.
• Do not expose the battery to excessive heat or cold or to direct
sunlight. Do not throw in the fire. Do not place the battery in
contact with water or other liquids.
• Charge the battery only with charging units intended for the
purpose and always use the balancer connection. It is only by
using the balancer connection that optimum charging can be
ensured. If this connection is not used, charging is subject to the
risks mentioned above. Before charging, always first allow the
battery to cool to ambient temperature. Never charge while hot.
• When charging, place the battery on a non-flammable, heat-
resistant support. There should be no flammable or readily
ignited objects in the vicinity of the battery.
• During charging or operation, never leave the battery
unsupervised.
• Do not fail to keep to the recommended charge/discharge
current.
• The battery casing must not be damaged. It is essential to
avoid damage by sharp objects such as knives or the like, from
dropping, impact, bending etc. Damaged batteries may no
longer be used.
• Batteries are not toys. They should be kept away from children.
3. Charging instructions
Lithium batteries are charged according to the CC-CV procedure.
CC stands for "constant current", which is applied during the first
phase of charging. Once the battery reaches the maximum voltage
configured in the charger, it switches to CV (constant voltage)
for the second phase of charging. The battery voltage no longer
increases. The charging current now falls continuously until the
battery is fully charged. The maximum charging current for the
battery is 1C (C=nominal capacity of the battery, e.g. for a battery
with a nominal capacity of 2700 mA, the maximum charging
current for the battery is 2700 mA (2.7 A)). Never charge several
batteries together from a single charger. Differing states of charge
and capacities can lead to overcharging and destruction.
4. Storage instructions
Lithium batteries should be stored charged to 20-50 % of their
capacity and at a temperature of 15-18 °C. If the cell voltage falls
below 3 V, they should be recharged. Deep discharge and storage
when discharged (call voltage <3 V) will render the battery
unusable.
5. General terms of guarantee
There is a legal guarantee for production and material faults as
applicable at the time of dispatch. No liability is accepted for
normal wear and tear. This guarantee does not apply for defects
attributable to improper use, inadequate maintenance, third-party
interference or mechanical damage. This applies, in particular, to
used batteries and batteries clearly showing signs of use.
Damage and loss of performance due to improper handling and/
or overload are not product faults. Batteries are consumables and
subject to a certain ageing. This is influenced by factors such as the
charge/discharge currents, the charging procedure, the operating
and storage temperatures and the state of charge during storage.
The ageing shows itself in, among other things, an irreversible loss
of capacity. In the model field, where batteries are frequently used
to supply motors, very high currents can flow from time to time.
6. Exclusion of liability
Since we are unable to have any control over charge/discharge,
handling, compliance with assembly and operating instructions,
battery replacement and its care and maintenance, TAMIYA /
CARSON can accept no liability for loss, damage or costs incurred.
Any claim for damages that may result from operation, failure or
faulty operation or that is in any way related thereto will therefore
be refused. We accept no liability for personal injury or material
damage and their consequences that arise from our delivery.
7.Disposal instructions
Batteries are hazardous waste. Damaged or unusable cells must be
disposed of in the correct manner.
No liability for printing errors, we reserve the right to make changes!
