    Safety test method

     

    drop test method

     

    the battery should be No explosion,No leakage,No fire

    The battery to be fully charged in accordance with stnadard charge condition, then drop the battery three times from a height of 1,0 m onto a concrete floor.

    The batteries are dropped so as to obtain impacts in random orientations.

     

    Vibration test method

     

    the battery should be No explosion,No leakage,No fire

    After standard charging, fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz and 55Hz, the excursion of the vibration is 1.6mm.

    The cell shall be vibrated for 30 minutes per axis of XYZ axes.

     

     

     

    Crush test method

     

    the battery should be No explosion,No fire

    Fully charged the battery in accordance with standard charge condition, the battery is to be crushed between two flat plates. Continuous to applied force on battery of 13kN(17.2Mpa),stopped until a pressure reading of 17.2Mpa is reached on the hydraulic ram

     

     

    Shock test method

     

    the battery should be No explosion,No fire

    The fully charged battery 

    The battery is subjected to a total of three shocks of equal magnitude.

    The shocks are applied in each of three mutually perpendicular directions.

    At least one of them shall be perpendicular to a flat face.For each shock the cell or battery is accelerated in such a manner that during the initial 3 milliseconds the minimum average acceleration is 75 gn.

    The peak acceleration shall be between 125 gn and 175 gn. Cells or batteries are tested in an ambient temperature of 20~25℃

     

    ALL SAFETY TEST FOLLOW THE UN38.3 STANDARD

     

    Warranty:

     

    1 Tac battery will be responsible for replacing the cell against defects or poor workmanship

    2 for 1years from the date of shipping.

    3 Any other problem caused by malfunction of the equipment or mix-use of the cell is not under this warranty.
