3.8V 3090mAh Cell for iPhone 6SP, 6P. and about the cell information as following: About Shock Test, The Cell is to be secured to the testing machine by means of a rigid mount which supports all mounting surfaces of the Cell. Each Cell shall be subjected to a total of three shocks of equal magnitude. The shocks are to be applied in each of three mutually perpendicular directions unless it has only two axes of symmetry in which case only two directions shall be tested. Each shock is to be applied in a direction normal to the face of the Cell. For each shock the Cell is to be accelerated in such a manner that during the initial 3milliseconds the minimum average acceleration is 75g (where g is the local acceleration due to gravity).The peak acceleration shall be between 125and175g. Cells shall be tested at a temperature of 20±5°C (68±9°F). About Forced-Discharge. A fully discharged Cell is to be force-discharged by connecting it in series with fully charged Cells of the same kind. The number of fully charged Cells to be connected in series with the discharged Cell is to equal the maximum number less one of the Cells to be covered for series use. Five Cells are to be fully discharged, at room temperature. Once the fully discharged Cell is connected in series with the specified number of fully charged Cells the resultant battery pack is to be short circuited. The positive and negative terminals of the sample are to be connected with a resistance load of 80±20mΩ. The sample is to discharge until a fire or explosion is obtained，or until it has reached a completely discharged state of less than 0.2 V and the battery case temperature has returned to ±10℃ of ambient temperature. The voltage at the end of the test may not reach 0.2 V due to operation of protective devices in the circuit. The return to near ambient of the Cell casing is an indication of ultimate results.
