6.3 General rules for using Li-Ion rechargeable batteries
- If you do not use the device for a prolonged period of time, then it is recommended to remove the
rechargeable batteries and store them separately.
- Store the half-charged battery pack in a plastic container placed in a dry, cool and well ventilated place
and protect them from direct sunlight. The battery pack may be damaged if stored when fully discharged.
The ambient temperature for prolonged storage should be maintained within the range of 5°C…25°C.
- Charge the batteries in a cool, well-ventilated place at a temperature of 10°C ... 28°C. Modern fast
chargers detect both too low and too high temperature of rechargeable batteries and react to the situa-
tion adequately. Too low temperature should prevent starting the process of charging, which might ir-
reparably damage rechargeable batteries. The increase in temperature of the battery pack may cause
electrolyte leakage and even its ignition or explosion.
- Do not exceed the charging current, as it may result in ignition or "swelling" of the battery pack. "Swol-
len" battery pack must not be used.
- Do not charge or use the batteries in extreme temperatures. Extreme temperatures reduce the lifetime
of rechargeable batteries. Always observe the rated operating temperature. Do not dispose the battery
pack into fire.
- Li-Ion cells are sensitive to mechanical damage. This kind of damage may cause its permanent dam-
age and thus - ignition or explosion. Any interference in the structure of Li-ion battery pack may cause
its damage. This may result in the ignition or explosion. A short-circuit of the battery poles "+" and "-"
may permanently damage the battery pack or even cause its fire or explosion.
- Do not immerse Li-Ion battery in liquids and do not store in humid conditions.
- If the electrolyte contained in the Lithium-Ion battery pack, contacts eyes or skin, immediately rinse the
affected place with plenty of water and consult a doctor. Protect the battery against unauthorised per-
sons and children.
- When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swelling, exces-
sive temperature), stop using the battery pack. Li-Ion batteries that are mechanically damaged, over-
charged or excessively discharged are not suitable for use.
- Any misuse of the battery may cause its permanent damage. This may result in the ignition. The seller
and the manufacturer shall not be liable for any damages resulting from improper handling Li-Ion battery
pack.
