Do you still not know how to choose lithium batteries?

With the increase in market demand, the lithium battery industry continues to expand. There are many brands of lithium batteries on the market, and it is difficult to distinguish between good and bad.

1. Look at the appearance

Looking at the appearance refers to the appearance, workmanship, size and craftsmanship of the lithium battery. Check whether the seam width of the shell is not wide, whether there are burrs, whether there are oil stains, and whether the feel is good. Advanced technology feels very comfortable. The rubber oil polishing material after grinding feels good and has strong insulation function.

2. Compare weight

The weight of a lithium battery is proportional to its capacity. If it is a polymer lithium battery, if the weight difference is too large, the capacity will definitely be insufficient, but the capacity of some batteries themselves is different. In addition, you can also sense from the outer packaging whether the weight of the battery is heavier. If it is heavy, it tends to be a high-quality lithium battery.

3. See if the capacity is clearly marked

Lithium batteries that do not clearly indicate the capacity are likely to be waste batteries or recycled batteries that have been reassembled using inferior batteries. There are many cheap lithium batteries on the market that are made of recycled or disassembled batteries. Although the price is cheap, the life span is short and the quality is unstable. Careless use may damage the device or even explode.

4. Look at the battery

Most of the cells used in lithium batteries are soft-pack cells and 18650 cells, which are also common lithium battery pack cell materials. First check whether the battery is brand new, because there are some bad small workshops on the market that use waste batteries to make lithium batteries. Soft-pack lithium batteries, also known as polymer batteries, are batteries with soft-pack electrolytes in the form of gel. They can be made into various shapes, and the battery is highly safe and will not explode.

5. Look at the brand

There are many brands of lithium batteries, but it is difficult to see the quality from the appearance. In this case, you need to do more homework before you choose, and check the manufacturer's information online. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers who have been in this industry for a long time are more trustworthy than those who have just entered the industry. If consumers do not know which brand of battery is good when buying, they will directly ask for batteries from big brands, because under the influence of brand practicality, the reliability and quality of the battery will be well guaranteed.
