3 Storage and Disposal
3.1 Cells should be stored in a well-ventilated, dry area at temperatures below 70 deg C. The optimum storage temperature
for maximum life is -10 deg C to +25 deg C.
3.2 In the event of a cell leaking, it should be carefully isolated from any other cells and placed inside a polythene bag.
If leakage occurs from a cell whilst connected to a printed circuit board it should be removed from the board as soon
as possible in order to avoid corrosion.
3.3 Should liquid electrolyte come into direct contact with the skin it should be removed by flushing with warm soapy
water.
3.4 In the case of fire use a dry powder extinguisher based on graphite (LITH-X) or other suitable extinguishers designed
for alkali metal fires. Water, CO2, or Halon extinguishers should not be used.
3.5 Cells and batteries should be disposed of in a secured land fill by arrangement with the local authority or by an
indepenedent contractor. Do not dispose of in fire. Prior to their disposal, cell terminals should be protected by tape
or other suitable means and be sealed in polythene bags. Cells and batteries should be fully discharged before
disposal.
4 Handling and Use
4.1 Do not attempt to charge or reverse charge cells. To do so may cause the cell to vent or explode.
4.2 Connecting cells in series could lead to reverse charging and this should only be carried out after advice.
4.3 Where there is any possibility of a charging current flowing, it is essential that the circuit for these cells should include
a blocking diode.
4.4 Do not short circuit. This may produce high temperatures and cell rupture.
4.5 Terminations must be suitably protected at all times when not connected to a circuit.
4.6 Do not crush, puncture, open, dismantle, or otherwise mechanically interfere with or abuse these cells.
4.7 Cells should not be connected together to form a battery.
4.8 Do not replace a fuse in a battery by a higher rated fuse or attempt to bypass the fuse
4.9 Observe correct cell polarity when inserting into equipment
