You’ll see, hundreds of batteries are clamped into vertical and horizontal battery cell capacity grading machine in battery cell manufacturing factory or battery pack assemble plant. Row after row, each cabinet can put hundreds of cells, namely hundreds of test points. The lithium cell is converted here to get the capacity, and know the size of the capacity, is the capacity. Through the capacity grading , to determine the level of the cell, (of course, to determine the level of internal resistance and other indicators) from this point we can see that lithium cell production is "electricity", and not some people think in the "no power state, and need to be activated before use"

Production of lithium batteries are not immediately sell, should be put in storage save less 15 days, in the meantime, some inherent disadvantages were shown, for example self-discharge is too big, and so on, in the garage reach the shelf life of batteries, after get the order, then take out again detection capacity, that is charge and discharge, the capacity can not meet the level, Or quality problems are eliminated, and then to maintain about 50% of the power to the sales department.

In effect, the cabinets are like chargers, except that they charge a large number of cells simultaneously and are managed by a computer to obtain data from each inspection point.

Battery cell assembly plant with battery cell capacity grading machine commonly, after received the batteries from batteries factory, to avoid to be deceived by batteries factory, and responsible for the consumer, the batteries for battery assembly again into machine capacity, through this process, the total can pick out some do not conform to the requirements of batteries, lithium battery testing mechanical testing, we can see, batteries, and through the charging and discharging,It's "powered."So some customers get the battery has little electricity, is normal.
