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!
