Parameters test of mobile phone lithium battery

　　(1) The parameter test of mobile phone lithium battery is based on the general standard rules. The lithium battery of mobile phone has overcharge maintenance, overdischarge maintenance, short circuit maintenance and discharge function tests.

　　(2) When conducting charging, over discharging and short circuit tests for mobile phone lithium battery, it is required that the battery shall not show smoke, fire, explosion, liquid leakage, electric leakage and other phenomena. There are two forms of discharge function test: 0.2C5A and 1C5A. When conducting 0.2C5A discharge test, the regular time shall not be less than 5 hours; When conducting 1C5A discharge test, the regular time shall not be less than 51 minutes.

　　(3) When the lithium battery of mobile phone is used for function test, it usually uses a medium that can transmit current. For example, the high current spring sheet micro needle module can pass the current within 1-50A in the mobile phone lithium battery test, and play a good connection function; In addition, it has a reliable way to deal with small pitches, and maintains a stable connection in pitches ≤ 0.2mm, without pin jamming and continuous needles. The stable function of the connection module is conducive to improving the test power of the lithium battery in mobile phones.
