Safety Precautions NiMH batteries:
1. General: Nickel-metal hydride (NiMH) 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. 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. Under no circumstances exceed these maxim values.
• 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: Before they are first used, NiMH
batteries must always be charged. The first charge should not be
carried out in rapid charge mode, otherwise the battery may not
reach its full capacity. We recommend a charging current of 1/10
of its capacity, i.e. charging at the 10-hour rate.. 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)). Exact
information for the charging current will be marked on the battery.
Charging should be stopped immediately if there is a significant rise
in battery temperature. !! Completely avoid deep discharge - in no
event should the cell voltage be allowed to fall below 0.9 V. It is not
necessary to always fully discharge the battery before each charge.
Occasionally (e.g. after every 10th charge), however, or if it has not
been used for a long time, it should be discharged before charging.
Never charge several batteries together from a single charger.
Differing states of charge and capacities can lead to overcharging
and destruction.
4. Storage instructions:
Batteries should never be stored at too high a temperature,
otherwise accelerated self-discharge will occur. Cool and dry
storage conditions are also important to avoid contact corrosion,
which leads to poor contact and high contact resistance. Batteries
should never be stored fully discharged.
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!
