How to identify the authenticity of a battery? How to distinguish a genuine battery from a camera ba

When you can tell if the camera battery is original, just look at what the words on the camera battery are printed with. Because if this camera is laser engraved, then your battery is original. If it is printed on the inkjet printer, and the workmanship is very rough, not so delicate.

Then this camera battery has been stolen and replaced. Now this is the only way to distinguish the camera battery. Because there are very few high-fidelity camera batteries produced, there is no need to worry about this.

Moreover, when buying a camera, first look at the outer packaging to see if there are signs of being broken or opened. Because each brand has a seal on the opening of the camera, it is generally impossible for the seal to be torn apart and glued, whether the outer packaging is intact when you buy the camera, these are the basis for determining whether the camera is an original accessory.

Here's an exampleI'll use the battery of the Canon SX230 camera I bought to pass it up, landlord, you compare it and see if it's the original! Generally, it is impossible to find the original seal of Canon after the destruction of the remaining merchants. If you have touched the accessories, then the camera case cannot be sealed, so that you can see whether the camera has been passive or not.

Canon battery. Canon battery.

Whether it is a battery or other accessories, we generally cannot tell whether the battery is original or not. If the battery with high imitation difference can be seen at a glance, if it is a good battery, it will be difficult to do. At this time, we can see if the outer packaging of the camera has been touched.

Welcome to the photography tutorial exchange.

Hope you find the above helpful!

01 Appearance. The workmanship of the original iPhone battery is very exquisite, the surface of the battery is relatively hard and flat, and the feel is comfortable; The appearance of the fake battery is far inferior to the appearance of the **, and there may be some irregular protrusions or depressions on the surface of the battery.

02 Adaptation of the battery to the phone. The original battery is specially set for iPhone, the workmanship is more fine, it is easier to install the battery, and the battery is easy to snap in; The fake battery is often due to the lack of fine workmanship, it is easy to appear that the battery position does not correspond, and it is easy to have problems during installation.

03 Printed labels. The printed label of the original battery is printed by secondary printing technology, so the color of the label and the barcode will be different theoretically; The words on the label of the original battery are very clear, and the font on the fake battery is easy to blur.

04 The condition of the front and rear cases of the battery. The front and rear shells of the original battery are tightly bonded and not easy to open; In order to save costs, the adhesion between the front and rear shells of fake batteries is often not strong and is easy to open.

The battery (referred to as the battery) is a wearing part on the car, the first power of the automobile electrical power, and an indispensable key component when the car starts. When car owners replace the battery, they often choose some big brands, such as: Wanli, Sail, Camel, Valta, Bosch, Yuasa, etc., the picture is a worry-free and durable.

However, many of these big brands in the market are counterfeit or refurbished. So for car batteries, how do we identify authenticity?

Under normal circumstances, the service life of the battery is claimed by the manufacturer to be about 2 to 3 years, but if you usually use the car more care, the battery maintenance is better, and there is no problem with using it for more than 5 years. The battery of the car was scrapped after 7 years, and I have seen the longest used car owner, and the battery was replaced after 12 years of purchase, which shows that the original battery is so powerful. However, whether the battery can achieve the same effect as the original factory depends more than half of your eyesight.

1. Look at the packaging: there is a more obvious color difference with **.

The outer packaging box of the regular battery is finely made and has a seal. When the box is opened, there will be a clearly printed and beautifully printed warranty card and product manual. If you buy in the auto parts city, most of the same brand of a variety of models of batteries fall together, the outer packaging should not have color difference, if you find that there is color difference, please choose carefully.

2. Look at the anti-counterfeiting verification: whether the number of the shell and the production date are clear.

After opening the package, most of the ** battery will be affixed with anti-counterfeiting labels, scratch off the anti-counterfeiting coating, dial the anti-counterfeiting query**, according to the voice prompts to check the anti-counterfeiting password, the correct anti-counterfeiting password can only be queried once, of course, different brands of battery anti-counterfeiting methods are different. If there is no anti-counterfeiting code, be sure to check the number and production date on the plastic shell of the battery to see if it is clearly marked.

3. Look**: low-cost batteries are greasy.

There are many battery models, and ** is also quite different. As far as the most commonly used 60 mAh battery for family cars is concerned, the price of ** in the auto parts city is about 450 yuan. If it is an imitation or refurbished battery, it may be more than 300 to buy, this kind of battery is not guaranteed at all, most of them are prepared for taxis, so you can't buy a battery cheaply.

4. Look at the weight: focus on comparing the weight of the old and new batteries.

Netizens who have experience in changing batteries must have this feeling, and the weight of a battery is really not small. Yes, that's right, because the cost of the battery is on the substrate made of lead alloy, and counterfeit batteries will make a fuss on the substrate to reduce the cost. Therefore, it is recommended that when you buy a new battery, you should weigh the weight to see if it is the same as the battery weight of the original car, if you feel that the new battery is not as heavy as the old battery, then it is likely to be a counterfeit.

There is a factory date on the upper side of the sail battery, preferably no more than 6 months after leaving the factory, and there is an anti-counterfeiting label on the upper end of the battery.

The upper face of the Varta battery has the date of appearance of the laser spray, the number indicates the year of manufacture, and the letter indicates the month.

Other manufacturers are also sprayed with the factory date, the best anti-counterfeiting is to find a more trustworthy company to replace, and don't be greedy for cheap, battery sales competition is fierce, the profit margin is less than 10%, if a certain ** is obviously low, you better not buy.

Method steps.

Method. 1. Amateur identification method:

1) For batteries of the same capacity, lithium batteries are lighter than nickel-metal hydride and nickel-cadmium batteries.

2) Charge the battery with a special charger for lithium battery, if the battery is heated during charging, it is a nickel-metal hydride and nickel-cadmium battery, and if there is no major change in temperature, it is a lithium battery.

3) Place the battery positive, negative, and pole"Instantly"Use after a short circuit, such as the battery"No power"It is a lithium battery, if still"There is electricity"It is nickel-metal hydride and nickel-cadmium batteries.

Method. 2. Professional identification methods.

1) With the help of special tools to identify anti-counterfeiting marks, there are more and more types of batteries on the market, and counterfeit technology is becoming more and more sophisticated, and some large companies are constantly improving anti-counterfeiting technology. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for people to identify the authenticity of batteries from their appearance.

2) Use a special detector to identify the quality of the battery, and it is difficult to distinguish the good and bad from the appearance alone. To this end, a battery detector has been launched on the market, which can detect and judge the capacity and quality of various batteries such as lithium, nickel-metal hydride and nickel-cadmium with a voltage and a capacity of less than 1999m·h, and has the functions of activation, charging and discharging. The whole process is controlled by the micro lithium according to the characteristics of the battery, which can realize the digital display of the measured voltage, current and capacity and other technical parameters.

Method. 3. Performance identification method.

To examine the battery performance, usually the battery working time is a relative concept, in short, the rated capacity of the battery should not be less than 95% of the standard capacity, fully charged for 28 days, the minimum capacity is not less than 60% of the rated capacity, and the battery life is not less than 400 times. If the battery does not meet the above criteria, it can be judged to be a fake. 4 methods.

4. Battery Trademark Inspection Law.

Check the identification of the battery, the state stipulates that the outer packaging of the battery should clearly indicate the trademark, factory name and address, the positive and negative poles of the battery, the rated capacity and the material, etc., of which the rated capacity is an important factor in measuring the mobile phone battery. If there is no logo or the mark is incomplete, it is considered to be a defective product.

In addition, the logo of the real battery is pasted with super glue, which is not easy to tear off. Fake batteries, on the other hand, may be able to tear off the entire label with just a single tear. 5 methods.

5. Charging process inspection method.

Observe the abnormal situation of charging, generally, there should be an overcurrent protector inside the lithium battery, and in the case of excessive current caused by external short circuit, etc., the circuit will be automatically cut off to avoid burning or damaging the electronic products. The lithium battery also has an overcharge protection circuit, which will automatically cut off the power supply when using non-standard electrical appliances and excessive alternating current. If in the process of charging, it is found that the battery is seriously heated or smoking, or even **, it means that the electric ground is fake.
