The mobile phone lithium battery is a finished battery composed of battery cell and battery protection board. The mobile phone lithium battery will be activated before leaving the factory. After a series of processes of filling the battery case with electrolyte-sealing-forming-dividing, the activation of the mobile phone lithium battery is completed.<\/p>\n

The activated mobile phone lithium battery also needs to be functionally tested. The purpose of the test is to verify whether the battery quality is qualified and to prevent the circulation of inferior batteries from the source. The mobile phone lithium battery test mainly uses power, switches, electronic loads, multimeters, and other instruments to test the battery\u2019s over-current and over-voltage, and checks whether the battery protection board can react quickly to protect the battery.In this process, we also need to use the battery test module \u2013 high current shrapnel microneedle module, which is mainly used for conducting current and transmitting signals.<\/p>\n

Mobile phone lithium battery testing is mainly carried out for functions such as functionality, safety, and reliability, because lithium batteries are prone to heat, expansion and even explosion due to overcharge, over-discharge, short circuit, and other reasons, so they must be tested to confirm whether it can be applied.<\/p>\n

The purpose of a mobile phone lithium battery functional test<\/strong><\/span><\/h2>\n

To test whether the function of the battery can be achieved. The test content: high and low temperature charge and discharge, charge retention capacity, battery rate, capacity, life cycle, etc.<\/p>\n

\u00a0<\/p>\n

The purpose of a mobile phone lithium battery safety test<\/strong><\/span><\/h2>\n

To test whether the battery protection board can cut off the current loop in time when the battery has abnormal conditions to avoid the occurrence of dangerous accidents. Test content: overcharge, over-discharge, abnormal charge, forced discharge, external short circuit, power limit detection, etc.<\/p>\n

\u00a0<\/p>\n

The purpose of a mobile lithium battery reliability test<\/strong><\/span><\/h2>\n

To test whether the battery can work normally in different external environments. Test content: low pressure, vibration, impact, crush<\/a>, free drop, impact, temperature change, shell stress, etc.<\/p>\n

\u00a0<\/p>\n

The mobile phone lithium battery test must ensure the stability of the current flow. As a battery test module, the high current spring micro pin module has good current transmission ability and can carry out current transmission in the range of 1-50a, and the over-current is stable and smooth, with no current attenuation. In the small pitch field, it can adapt to the pitch value between 0.15mm-0.4mm. It has excellent service life and stability, can maintain a good connection, and won\u2019t be stuck with a PIN or broken needle.<\/p>\n

In addition to battery quality, cell phone lithium battery testing must also consider how to increase battery output, reduce production costs, and maximize benefits. Under the high-frequency test, the average service life of the high current shrapnel microneedle module can reach more than 20w times. If the operation, environment, and maintenance are good, the service life can reach 50w times, and the shrapnel head has a self-cleaning design, which can maximize the use, and greatly improve the testing efficiency of mobile phone lithium batteries.<\/p>\n

In addition, the high-current shrapnel microneedle module has a short delivery time and high yield, which\u00a0can maintain long-term stability in the mobile phone lithium battery test. It is a battery test module with absolute advantages and ultra-high adaptability.<\/p>\n
