Select the five kinds of electric lithium battery? Do you want to learn

Select the five kinds of electric lithium battery? You learn to pick the lithium battery method one: check the appearance and packing will be on the packaging and appearance to judge the lithium battery products. Although the general product appearance is deceptive, but also can filter out some bad products from the appearance. Selected lithium battery method 2: look at the product batteries first check for new batteries, because there are some bad small workshops on the market use used batteries production of lithium-ion batteries. Good batteries, higher safety, lithium battery quality is better! Selected method three: lithium-ion batteries in the process of testing work charged in lithium battery charged, 10 minutes continuous discharge the battery polarity if not hot, battery protection board system perfect, general with high-quality lithium-ion battery protection board quality is better than ordinary lithium batteries. Four selected lithium battery method: to compare the weight and the weight of the lithium battery capacity is proportional to the, if is the polymer lithium-ion batteries, the weight difference is too big, capacity is not for certain, but there are some differences between the size of the battery itself. In addition, from the outer packing perception about the battery weight is heavy, if the thick towards high quality lithium batteries at all. Selecting lithium battery method 5: test impedance and the maximum current actually, judge the fastest lithium battery performance testing method is to test internal resistance and the maximum discharge current. Good quality lithium battery, internal resistance is very small, maximum discharge current is very large. Using a range of 20 multimeter, short directly connect the two electrodes of lithium-ion batteries, generally should be around 10 a current, or even higher, and can maintain for a period of time, relatively stable is good battery. Above is the electric lithium battery to choose method of photoelectric for everyone to share.
