Some points that must be paid attention to when purchasing lithium batteries

Buying a poor-quality lithium battery pack is like putting a time bomb around you. Therefore, consumers must pay attention to the following points when buying lithium batteries: 1. Whether the capacity is clearly marked. Lithium batteries that do not have a clearly marked capacity, such as 2200mAh or 4400mAh, are likely to be worn-out batteries or recycled batteries assembled from scratch. 2. When purchasing a lithium battery pack, customers should choose products from a regular lithium battery manufacturer. The specifications of the lithium battery should be consistent with the specifications of the mobile phone, and it is best to buy the original battery. 3. Whether to guarantee the standby time. Standby time refers to the continuous use time from the time the lithium battery is loaded into the mobile phone to the next charge. 4. Whether there is a safety maintenance circuit. The characteristics of the lithium battery solve that the lithium battery must be added to the maintenance board. In order to prevent the occurrence of lithium battery overcharge, overdischarge and short circuit, the lithium battery without a maintenance board will cause the lithium battery to deform, leak, and explode. 5. Look at the appearance, craftsmanship, size and technology of the lithium battery pack energy storage power supply. Look at the seams of the shells, see if the width of the seams is not wide, whether there are burrs, or oil stains. It feels good and does not feel good. The advanced technology is very comfortable. After polishing, the rubber oil polishing material has a good feel. The upper insulation function is very strong. 6. Choose manufacturer and brand. There are many domestic lithium battery energy storage power supply brands, which are difficult to see from the appearance quality. In this case, we must do more homework before choosing, and more information about the manufacturer goes to the Internet. Generally speaking, professional manufacturers are more reliable than small workshops; companies with long-term relevant experience are more trustworthy than those new to this field. 7. Product parameters. The energy storage power of the lithium iron phosphate battery pack is the most important parameter inside the battery, and it is the best choice for the lithium iron phosphate battery as the battery power source. 1. Take a look at the battery. The most commonly used lithium batteries are soft pack batteries and 18650 batteries. First, check whether the batteries are brand new, because there are bad examples of small workshops using second-hand batteries to make lithium batteries. The soft-packed lithium battery, also known as a polymer battery, is a battery with a bendable, gel-like electrolyte that can be made into various shapes. The battery is safe and will not explode. In 18650, the liquid electrolyte has a large capacity, may explode, and has a low safety factor. 2. Weight The weight of a lithium battery is directly proportional to its capacity. If it is a polymer lithium battery, the weight difference is too large, and the capacity will inevitably be insufficient. But the size of some battery capacity is different, so this is also attributed to that, so find some relatively high lithium battery manufacturers to promise good battery operation, in order to reduce costs, many people use batteries with poor quality and maintenance, empty standard capacity , So you must be careful when buying to prevent being deceived.
