Lithium batteries are divided into lithium-ion batteries and polymer lithium batteries. The electrolyte of lithium-ion batteries is flowing, while the electrolyte of polymer lithium-ion batteries is solid. Therefore, lithium-ion batteries are more unstable than polymer lithium-ion batteries, and may cause battery explosions when hit by external forces or when using non-standard chargers. Therefore, when purchasing lithium batteries, it is important to pay attention to the following points:

Check if the appearance is clearly marked

Looking at the appearance refers to the appearance, workmanship, size, and craftsmanship of a lithium battery. Check whether the seam line of the shell is wide, whether there are burrs, oil stains, and whether it feels good to the touch. Advanced technology makes it feel very comfortable. After polishing, the rubber oil polishing material not only has a good feel, but also has strong insulation performance. Is the capacity clearly indicated. Lithium batteries without clearly labeled capacity (such as 2200mAh or 4400mAh) are likely to use inferior or recycled battery cells,

Reassembled garbage batteries. There are many cheap lithium batteries on the market, which are made from recycled or dismantled battery cells. Although they are cheap, their lifespan is short and their quality is unstable. Improper use may damage phones and even cause explosions.

Is standby time guaranteed

The standby time refers to the continuous usage time from the lithium battery installed in the phone to the next charging. Lithium batteries sold in the general market cannot guarantee standby time for customers due to unstable battery quality. Many cheap batteries have short standby time due to the use of poor quality battery cells.

Look at the protective board

Is it equipped with a safety protection circuit. The characteristics of lithium batteries determine that they must be equipped with protective plates to prevent overcharging, discharging, and short circuits from occurring,

Lithium batteries without protective plates pose a risk of deformation, leakage, and explosion. In the fierce price competition, battery packaging factories are seeking lower priced protective circuits or simply omitting this device, making the market full of lithium batteries with explosive risks. Consumers cannot distinguish whether there is a protective circuit board from its appearance, so it is best to choose reputable merchants to purchase.

Look at the brand

There are many brands of lithium batteries, but the quality is difficult to see from the appearance. In this situation, everyone should do more homework and check the manufacturer information online before making a choice. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers who have been in the industry for a long time are more trustworthy than those who have just entered the field.
