Pay attention to the points of choosing lithium batteries

Lithium batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of a lithium-ion battery is fluid, so it is more unstable than a Lithium-Polymer battery, hitting an external force, or using a non-standard charger can cause the battery to explode. Many portable electronic devices such as mobile phones and laptops use lithium batteries. For safety reasons, what are the precautions we have in purchasing lithium batteries?

See if you can guarantee standby time.

The standby time is the continuous use of the battery from the time it is loaded into the phone to the next charge. Batteries sold on the general market can not guarantee standby time for customers. This is because of the unstable quality of batteries. Many cheap batteries have a short standby time because they use poor quality battery hearts.

First, see if there is a clear capacity.

Batteries with no clearly marked capacity(such as 1000 mAh or 1000 mA hours) are likely to use inferior batteries or recycled batteries. Many of the cheap batteries on the market are made from recycled battery cores. Although the price is cheap, the life span is short and the quality is unstable. Careless use may damage the mobile phone.

Third, see whether to install a safety protection circuit board.

Without a protected circuit board, lithium batteries are in danger of deformation, leakage, and explosion. Under the vicious price reduction competition, each family seeks lower price protected circuit boards, or omits the device at all, making the market full of lithium batteries that are dangerous to explode. Consumers can not tell from the appearance whether there is a protected circuit board, so it is best to choose a reputable merchant to buy.
