In lithium battery production test, self-discharge has always been an important consideration. The traditional test method will be used to test the battery's open-circuit voltage (OCV)test, through the observation of the open-circuit voltage over time can be calculated by the battery's values, but this traditional test method needs a long time to stand still to make the open-circuit voltage sufficiently change. However, this traditional test method requires a long period of time for the open- circuit voltage to change sufficiently to determine whether the self-discharge capability of the product is within the permissible range. Because of the large production capacity of current battery manufacturers, this method of testing can result in the production of batteries bei<span style=";font-family:'Times New R
l Fast recognition of the self-discharge current with a minimum time of 30min;
l Output voltage 0.5V-5V;
l Ultra high output stability, voltage output fluctuation Vpp<10μV;
