First, look at the trademark

When you buy a SONY battery, look at the manufacturer's logo on the battery surface, including the logos of "Sony" and "infoLITHIUM" and the product model. The logo on the surface of the original SONY battery is clear and accurate, and there is a black and white "Sony" logo on the back of the battery. Some fake batteries don't. If the logo on it is distorted and the font is wrong or unclear, it must be fake.

Second, the safety sign

There is a Sony safety sign on the outer packaging, which is also a very obvious difference between genuine and fake batteries: the real battery safety sign has a strong three-dimensional sense, like the surface of our ID card now, while fake batteries generally have no three-dimensional sense and the font is relatively vague, and some people even arrange different orders.

Third, observe the printing quality

Besides looking at the trademark, you can also tell the difference by the printing quality on the battery surface. The fonts printed by real batteries are the same size and can be read clearly; On the other hand, the typography of fake batteries suddenly became thin and fuzzy. And the location of the "qualified" label. The "qualified" label of the real Sony battery is under the battery, and the "qualified" label of the fake battery is above the battery.

the last trick is to look at the quality of the packaging. The outer surface of the real battery is smooth, while the outer surface of the fake battery is rough and uneven. The plastic shell of a real battery will fluctuate up and down with the shape of the battery, with edges and corners, while the plastic shell of a fake battery has no edges and corners. Finally, remind consumers to polish their eyes when buying Sony batteries, so as not to cause unnecessary economic losses

Extended information:

Maintenance and use of Sony batteries:

1. Avoid full discharge

2. Always charge and discharge lithium batteries, charge them when they are not fully discharged, use an external power supply, use them while charging, or continue after charging.

3. When it is not used for a long time, the lithium battery should be taken out and placed in a cool and dry place. Never freeze to avoid water vapor erosion. If it is stored for a long time, charge the battery to 4% and leave it.

4. The battery needs to be activated

from the battery factory to the user's hand, which sometimes takes a long time, ranging from one month to half a year. At this time, because the battery electrode material will be passivated, the manufacturer suggests that the battery used for the first time should be fully charged and discharged for 3-5 times in order to eliminate the passivation of the electrode material and reach the maximum capacity.

5. It doesn't need to be charged for 12 hours for the first three times

Because of the need for replenishment and trickle charging process, it may take about 5 hours to reach the most perfect state of charge, but it doesn't need 12 hours. The constant current and constant voltage charging characteristics of lithium-ion battery determine that its deep charging time does not need 12 hours.
