How to distinguish the true and false mobile phone lithium battery?

At present, nickel-metal hydride, nickel-cadmium, lithium-ion and lithium-polymer batteries have been used on the market to impersonate lithium metal batteries. Experts remind you that you can use the following methods to detect authenticity:

1, self-discharge rate. Lithium-ion batteries are 8 months per month; Lithium polymer battery is 20 m/month; Nickel hydrogen and nickel-cadmium batteries are 100 per month; The lithium metal battery is 1 <UNK> -2 <UNK> / month.

2, lithium series batteries have no memory effect.

3, insert the special test card into the digital machine, press the "#" key to enter the test state, and then press "490 #", if the mobile phone shows "BatteyRDFail" is a fake lithium battery.

4, lithium batteries are identified in English as Li, nickel-metal hydride and nickel-cadmium batteries are NIMH and NICD.

5, false lithium battery bar code dark layer.

6, the original battery plastic pressure film mold is precise, once formed, the appearance is neat, no hair thorn, feel good.

7, the battery label writing is clear, there is a battery scale corresponding to the battery type, with a metal marking and white scratch.

At present, the mobile phone is an indispensable tool for people, and it is very fast to upgrade. The battery life of the mobile phone is limited, so sometimes the cell phone is still good, but the battery is already very unused. At this time, it is necessary to buy a new cell phone battery. So, how do you pick lithium batteries for your phone? Let's follow the editor.

Method / step:

1, there is no indication of clear capacity. Batteries with no clearly marked capacity 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 equipment.

There is no guarantee of standby time. The standby time is the continuous use time of the battery from the time it is loaded into the device 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.

3, whether or not 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.

4, the battery tag writing is clear, there is a battery part number corresponding to the battery type, and the corresponding position below the electrode is marked with "+", "-'' mark.

5, charging test. If lithium-ion batteries are not charged for long, the phenomenon of scalding occurs, then the battery is probably inferior.
