A few tips to help you choose a good lithium battery!

2022-09-28 15:00

Lithium ion battery has the characteristics of light weight, large energy storage, large power, non-pollution and so on, it is widely used in every fields, its research and production have made a great process. Lithium ion battery is used as power source on electric vehicles, which becomes a new trend in development of electric vehicles.


So how to choose a good lithium battery? The following tips can be used:


1. Check the appearance and packaging

Firstly, we can observe lithium battery products from the packing and appearance. Although the appearance may not represent the root of a product, but a good product will not leave the old appearance, appearance has a certain deceptive, but also can screen out some inferior products from the appearance.


2. Compare the weights

Although the volume of lithium ion battery is small and capacity is large, its weight is proportional to the capacity. If it is a polymer lithium battery, the difference of battery is too large, the capacity must be insufficient, although there are differences in the size of the capacity of some batteries themselves. In addition, you can only feel whether the weight of the battery is relatively heavy from the outer packaging. If the battery is heavy, it will prefer to be a high-quality lithium battery. Therefore, you can choose the relatively heavy lithium battery when you purchase.


3. Test internal resistance and maximum current

If conditions permit, you can choose the maximum current of the test internal resistance, because the fastest test method to determine the performance of lithium battery is to test the internal resistance and the maximum discharge current. For good quality lithium batteries, the internal resistance is very small, and the maximum discharge current is very large. For example, the multimeter with 20A range is used, and the two electrodes of the lithium battery are directly short-connected. The current should generally be about 10A, or even higher, and can be maintained for a period of time. The relatively stable battery is a good battery.


4. Detect live work

Generally lithium battery quality with high quality protection board is better than ordinary lithium battery. When lithium battery is under live working, continuously discharge for 10 minutes, if battery poles do not get hot, it means this lithium battery is with high quality protection board, and battery protection board system is perfect.


5. Check the cell  

Most of the cells used in lithium batteries are soft-pack cells and 18650 cells, which are also relatively common lithium battery pack cell materials.  First check whether the cell is new, because there are some bad small workshops on the market using second-hand cells to make lithium batteries.  Soft pack lithium cell, also known as polymer cell, is a kind of battery with soft and its electrolyte is gelatinous , which can be made into a variety of shapes, the battery safety is high and will not explode. 


During our lives, it is important to choose a good lithium battery for use, but we should also pay attention to the method of use and carry out appropriate operation.  At the same time, the lithium batteries with problems should be repaired or scrapped in time to avoid unnecessary trouble.
