Analysis: the lithium battery capacity of qi unknown side!

This is a rechargeable battery empty mark the story behind the capacity! Qi is false and exaggerated, amplify the original parameters ( Exaggerated) To attract attention; So virtual battery capacity mark behind what is the secret of the unknown, can with this article trickled in together. 1, what is the battery capacity empty mark? Battery capacity is the enlarged or overstate actual battery capacity parameters, the purpose is to attract consumer attention and can sell a good price. For example A: suppose section 18650 li-ion battery of battery capacity is 2200 mah, manufacturer logo on battery is 5000 mah, then it belongs to the battery capacity qi phenomenon. Rechargeable batteries, for example, B: in this paper, the title is' empty mark the unknown story behind the capacity! ', if I will be the title as' new technology, single section 18650 battery capacity exceeding 30000 mah ', so this is attractive, but there is no truth, illegal. 2, what's behind the 'dirty' manufacturer of battery capacity of qi interest? Basically is to 'fetch a good price. For example, C: suppose a 3. 7 v2000mah lithium-ion battery pack, its battery power is 7. 4 wh, so if the lithium battery pack are identified as 3. 7 v5000mah, then its battery power becomes 18. 5Wh。 If per Wh to 2. 5 yuan tax price, battery manufacturers can sell 27. 75 yuan, the profit for 'dirty' workshop of the factory is very yearning. Extension: battery energy X = nominal battery voltage battery nominal capacity. 3, the most easy qi? Qi capacity seemingly begins shanzhai mobile phone battery, the earliest known early popular shanzhai mobile phone ring tones, battery capacity just a look at more than 3500 mah, mostly are the time square aluminum shell of the battery capacity is hard do 3500 mah should be. Qi began spreading at this moment, such as mobile phone sd card standard capacity, cell phone memory capacity of qi, u disk capacity of qi, mobile power supply capacity of qi, etc. , in fact, the most easy to see how should belong to the mobile power charging treasure qi, some around the train station has a lot of street type of selling rechargeable batteries treasure, but most of these charge treasure capacity is 10000 mah, which sells for about 30 yuan, you can imagine. 4, how to identify the battery capacity virtual standard. Net friend gave a picture, this picture is the empty mark your battery capacity, as a case, a description. Above the battery logo is 7 18650. 4 v - 5200 mah, could see plainly it was 2 18650 batteries, lithium batteries, so why is it empty mark? Together to do A simple analysis is as follows: A, if the two batteries in series voltage is 7. 4 v, this was no exception. B and 18650 normal batteries in the majority with 2600 mah capacity, parallel to 5200 mah also no exception. Key lies in the single 18650 batteries, no 5200 mah, including import samsung batteries, panasonic, SONY battery, etc. , the author also consulted the domestic 18650 batteries manufacturer, 18650 batteries does 3000 mah capacity. Small extension knowledge: this 18650 lithium batteries nominal voltage is 3. 7 v, in series to increase voltage, in parallel to increase capacity. Given above batteries capacity is 2600 mah, then the problem is here. If the above two batteries of lithium-ion battery pack for the tandem, then its logo should be 7. 4V 2600mAh。 If the above two batteries of lithium-ion battery pack for parallel, then it's logo should be 3. 7V 5200mAh。 So make sure above the battery logo has a lot of empty mark, encounters this phenomenon should be looking for relevant departments complaints. Read the article do you have your own ideas or opinions? Virtual target is illegal, if your battery is suspected of qi, do not find the author talk about prevention, together to analyze the complaints.
