8. Mechanical Characteristics
 
  8.1 Drop Test
Test method: Cell(as of shipment or full charged) drop onto the oak-board
(thickness:  ≥ 30mm) from 1.5m height at a random direction 6 times.
      Criteria: No leakage
   
8.2 Vibration Test
       Test method: Cell(as of shipment) is vibrated along 2 mutually
                   perpendicular axes with total excursion of 1.6mm and with   
                  frequency cycling between 10Hz and 55Hz by 1Hz/min.
Criteria: No leakage
 
9. Safety
 
  9.1 Overcharge Test
      Test method: To charge the standard charged cell with 12V and 2.6A at 25℃   
                  for 2.5 hours.
      Criteria: No fire, and no explosion.
 
  9.2 External Short-circuit Test
      Test method: To short-circuit the standard charged cell by connecting positive and   
                  negative terminal by less than 50mΩ   wire for 3hours.
      Criteria: No fire, and no explosion.
 
  9.3 Reverse Charge Test
Test method: To charge the standard charged cell with charge current 2.6A   
By –12V for 2.5 hours.   
      Criteria: No fire, and no explosion.
 
9.4 Heating Test
        Test method: To heat up the standard charged cell at heating rate 5℃  per minute up to
                  130℃  and keep the cell in oven for 60 minutes.
      Criteria: No fire, and no explosion.
