Common fake battery identification method

1. The average Ni-cd battery is 500mAh or 600mAh, and the Ni-mh battery is only 800-900mAh. The capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the time for the lithium battery to be fully charged is about 1.5 times that of a nickel-hydrogen battery is about 3.0 times that of a nickel-cadmium battery. If you find that the working hours of the lithium-ion mobile phone battery block you purchased are not advertised or as long as specified in the manual, it may be counterfeit.

2. If we find that the battery is extremely hot or smokes or even explodes during charging, the battery is definitely fake.

3. If a lithium-ion mobile phone battery block is faked with a cadmium-nickel or a hydrogen-hydrogen battery block, it must be composed of five single-cell batteries. The charging voltage of a single battery generally does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75V. When the total charging voltage of the battery block is lower than 8.0V, it may be a Ni-cd or Ni-mh battery.
