What should you pay attention to when shopping for lithium batteries?

The news about the "mobile phone explosion" is endless. Fake and shoddy batteries are the culprits of the mobile phone explosion. At present, the batteries used for mobile phones are mostly lithium batteries. Experts remind consumers that the following points should be noted when purchasing lithium ion batteries for mobile phones:

First, look at the nickel-cadmium battery with a general capacity of 500mAh or 600mAh, and nickel-metal hydride battery is only 800-900mAh; The capacity of lithium-ion cell phone batteries is generally between 1300 and 1400 mAh, so lithium-ion batteries are used about 1.5 times as long as nickel-metal hydride batteries and about 3.0 times as nickel-cadmium batteries.

Second, look at the appearance of the original battery anti-wear surface is uniform, the use of PC material, no brittle cracking phenomenon; Counterfeit batteries without anti-wear or too rough, the use of recycled material, brittle crack. The surface color of the mobile phone battery is clear, uniform, clean, and without obvious scratches and damage. The hardware sheet has no obvious scratches and black and green phenomena. The color of the battery bottom shell is the same as that of the mobile phone body. It matches well with the mobile phone and the lock is reliable.

Third, look at the logo of the original battery label should be printed with the battery model, type, rated capacity, standard voltage, positive and negative pole logo, manufacturing factory name.

Fourth, look at the protection device. There should be an over current protector inside the mobile phone battery. If the external short circuit causes excessive current, automatically cut off the loop so as not to burn or damage the mobile phone. If the battery is found to be seriously hot, smoking, or even exploding during the charging process, the battery must be false.

Fifth, look at the Anti-Counterfeiting logo, such as the NOKIA original battery sticker hidden under the embossed NOKIA words, Motorola battery's Anti-Counterfeiting trademark is diamond, and from any angle, flashing has a three-dimensional effect. On the contrary, the Anti-Counterfeiting logo is dark in color and not enough in three-dimensional sense, it may be a fake.

If the battery blocks of nickel-cadmium and nickel-metal hydride are used to counterfeit the battery blocks of lithium ion mobile phones, the voltage measured must consist of five single batteries. The charging voltage of a single battery generally does not exceed 1.55 V. When the total voltage of the battery block is less than 8.0 V, it may be nickel-cadmium and nickel-metal hydride batteries.
