CAUTION
1 Reverse charging is not acceptable.
2 Charge before use. The cells / batteries are delivered in an uncharged state
3 Do not charge / discharge with more than the specified current.
4 Do not short circuit the cell / battery. Permanent damage to the cell / battery may result.
5 Do not incinerate or mutilate the cell /battery.
6 Do not solder directly to the cell /battery.
7 The life expectancy may be reduced if the cell / battery is subjected to adverse conditions like:
extreme temperature , deep cycling , excessive overcharge / overdischarge.
8 Store the cell / battery uncharged in a cool dry place. Always discharge batteries before bulk
storage or shipment.
9 For storage of cells/ batteries over one year, in order to prevent the degrading of the function
of cells, cells / batteries should be at least charged and discharged once trimester.
Keep away from children. If swallowed, contact a physician at once.
10 Air ventilation should be provided in the plastic case of batteries,
otherwise it may have a risk of accumulating gas (oxygen gas, hydrogen gas)
generated inside the cell resulting in explosion triggered by fire sources (motors or switches).
Airtight battery compartments are strongly discouraged.
11 The batteries comply with Restrictions on Hazardous Substances (RoHS) Direction.
