How to distinguish the quality of lithium batteries

1. The fastest test method is to test the internal resistance and maximum discharge current. Regarding high-quality lithium batteries, the internal resistance is very small and the maximum discharge current is very large. The 20A range multimeter is used to directly short-circuit the two electrodes of the lithium battery. The current should be around 10a, or even higher, which can be maintained for a period of time, and relatively stable is a good battery. 1. Look at its appearance. The fullness of the appearance, such as a general 2000mAh lithium battery, is larger. The craftsmanship is more refined or the packaging looks fuller. 2. Look at the hardness. The middle part of the lithium battery can be clamped manually or moderately. The hardness is moderate and there is no soft squeeze feeling, which proves that the lithium battery is a relatively high-quality battery. 3. Look at the weight. Remove the outer packaging and check whether the battery is heavy. If it is thick, it is a high-quality battery. 4. During the live working process of the lithium battery, if the two poles of the battery do not burn for about 10 minutes after continuous discharge, it proves that the battery protection board system is perfect. Generally speaking, the quality of high-quality protection board lithium batteries is better than ordinary lithium batteries. These are the issues that robots should pay attention to when buying lithium batteries, and how to detect the quality of lithium batteries.
