9, aging test
1, the test steps:
①, assembled semi-finished products, with 20W / 5R resistive load will be put (1A load).
②, will be finished the finished semi-finished products, with a 5V / 1A charger to charge it, observe the status of the display and whether the same OK.
③, will be fully charged semi-finished products, with 20W / 5R resistor load on its discharge, observe the status and specifications are consistent OK, the test is completed.
④, will be finished finished semi-finished products, with a 5V / 1A charger to charge, to reach 70% stop charging, can be assembled products.
⑤, assembled after the finished product, with 20W / 5R resistive load and 5V / 1A charger to do charge and discharge testing to prevent damage during assembly.
