CONFIGURATION, DIMENSIONS AND MARKINGS Please refer to the attached drawing. Within 1hour after standard Charge, 24h with 1 /cell load. The charged battery is stored for 1 days at 33±3 O C and 8±5% of relative humidity. Forced discharge is conducted for 1hour at a constant current of 17mA(1C) after pre-discharge at a constant current of 34mA(.2C) up to V. The battery is subjected to a drop, which has a height of 45cm(17.7 inches) to an oak board of 1mm or more thick in a voluntary axis respectively 3 times. 6. EXTERNAL APPEARANCE The cell/battery shall be free from cracks, scars, breakage, rust, discoloration, leakage nor deformation. (see Note 5)
7. 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 our 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 adverse conditions like: extreme temperature, deep cycling, excessive overcharge/ over-discharge. (8) Store the cell/battery uncharged in a cool dry place. Always discharge batteries before bulk storage or shipment.
8. Notes: (1) Approximate charge time from discharged state, for reference only. (2) We recommend cells or batteries are charged at least once every 6 months.
