How to choose lithium-ion batteries correctly

1. Is the capacity clearly marked? Batteries without a clearly marked capacity (such as 1000mAh or 1000 mAh) are likely to use inferior batteries or recycled batteries. Many cheap lithium-ion batteries on the market are made from recycled battery cores. Although they are cheap, they have short lifespan and unstable quality. Careless use may damage the phone. 2. Is there any guarantee of standby time? The standby time is the continuous use time after the battery is installed in the phone to the next charge. Generally, the batteries sold in the market cannot guarantee the standby time for customers. This is because the quality of the power lithium-ion battery is unstable, so the standby time is very short. 3. Whether to install a safety protection circuit board. Without the protection circuit board, there is a danger of deformation, leakage, and leakage of the lithium-ion battery. Under the vicious price cut competition, various companies seek low-priced protection circuit boards, or omit this device at all, making the market full of dangerous lithium-ion batteries. Consumers cannot tell from the appearance whether there is a protective circuit board, so they choose to buy from a reputable merchant. 4. Detection of live working. During the live working process of the lithium-ion battery, continue to discharge for about 10 minutes. If the battery poles are not hot, it proves that the battery protection board system is perfect. Generally, the quality of lithium-ion batteries with high-quality protection boards is better than ordinary lithium-ion batteries. Great. 5. Comparison of weight The weight and capacity of lithium-ion batteries are directly proportional. If it is a polymer lithium-ion battery, if the weight difference is too large, the capacity will definitely be insufficient, but there are differences in the size of the capacity of some batteries. In addition, you can also feel the weight of the battery from the outer packaging. If the weight is heavy, it is biased towards high-quality lithium-ion batteries. Whether the capacity is clearly marked. Lithium-ion batteries without a clearly marked capacity (such as 2200mAh or 4400mAh) are likely to be garbage batteries reassembled with inferior battery cells or recycled battery cells. There are many cheap lithium-ion batteries on the market, which are made from recycled or disassembled battery cells. Although they are cheap, they have short lifespan and unstable quality. Careless use may damage the phone or even explode. 2 Whether to guarantee the standby time. The standby time is the continuous use time after the lithium-ion battery is loaded into the mobile phone to the next charge. Generally, the lithium-ion batteries sold in the market cannot guarantee the standby time for customers. This is because the battery quality is unstable. Many cheap batteries use poor-quality battery cells, so the standby time is very short. 3Whether with safety protection circuit. The characteristics of lithium-ion batteries determine that lithium-ion batteries must be equipped with a protective plate to prevent overcharge, over-discharge and short circuit of lithium-ion batteries. Lithium-ion batteries without protective plates may deform, leak, and explode. Danger. In the fierce price competition, various battery packaging factories seek lower-priced protection circuits, or omit this device at all, making the market flooded with lithium-ion batteries that are dangerous for explosions. Consumers cannot tell from the appearance whether there is a protective circuit board, so it is best to choose a reputable merchant to buy.
