WARNING:
-
Li-Ion cells are very sensitive to charging characteristics and may explode if mishandled.
-
Make sure user has enough knowledge on Li-Ion rechargeable batteries in charging, discharging and assembly before use.
-
Strongly suggest that you use PCB-module or a Li-Ion Battery recharger.
-
Never use conventional DC adapter.
-
We are NOT responsible for any damage that is caused by the misuse of the Li-Ion Battery
Caring for
-
Charge battery with good quality Lithium Polymer charger. A poor quality charger can be dangerous.
-
Set voltage and current correctly (failure to do so can cause fire).
-
Please check cell voltage after the first charge.
-
Example: 1-Cell: 4.2V (4.15 to 4.22)
-
-
Do not discharge battery to a level below 2.5V per cell under load. Deep discharge below 2.5V per cell can deteriorate battery performance.
-
Use caution to avoid puncture of the cell. Puncture of cells may cause a fire.
The symbol with the crossed out garbage can (§ 17 paragraph 1 Battery Act) means that the disposal of batteries and accumulators in the household waste is prohibited by law. On batteries and accumulators you can find the chemical signs "Hg" (mercury), "Cd" (cadmium) and "Pb" (lead) (§ 17 paragraph 3 Battery Law). If more than 0.0005 mass percent mercury, 0.002 mass percent cadmium or 0.004 mass percent lead is present, batteries and accumulators must be marked with the symbols "Hg", "Cd" and "Pb".
Cd = battery contains cadmium
Hg = battery contains mercury
Pb = battery contains lead
Mh = battery contains metal hydride
