Check whether the appearance is clearly marked

Look at the appearance refers to the appearance, workmanship, size and process of lithium battery. Check whether the shell seam line width is not wide, whether there is burr or oil stain, and whether it feels good to the touch. Advanced processes are very comfortable to the touch. After polishing, rubber oil polishing materials have good hand feel and strong insulation performance. Whether the capacity is clearly marked. Lithium batteries without clearly marked capacity (such as 2200mAh or 4400mAh) are likely to use low-quality battery cells or recycled battery cells.

Reassemble the garbage battery. There are many cheap lithium batteries on the market, which are made of recycled battery cells or disassembled battery cells. Although the price is cheap, the life is short and the quality is unstable. Careless use may damage the mobile phone, or even explode.

Whether standby time is guaranteed

Standby time refers to the continuous use time from the time the lithium battery is loaded into the phone to the next charging. Generally, lithium batteries sold on the market cannot guarantee the standby time for customers. This is because the battery quality is unstable. Many cheap batteries use poor battery cells, so the standby time is very short.

Look at the protective board

Whether safety protection circuit is provided. The characteristics of the lithium battery determine that the lithium battery must be equipped with a protective plate to prevent overcharge, overdischarge and short circuit of the lithium battery.

The lithium battery without protective plate may be deformed, leaked and exploded. In the fierce price competition, battery packaging plants seek lower price protection circuits, or simply omit this device, making the market full of explosive lithium batteries. Consumers can't tell whether there is a protective circuit board from its appearance, so it's better to choose a reputable merchant to buy it.

Look at the brand

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