The 16340 flashlight generally has a capacity of around 400MAH, the maximum capacity is 800MAH, and the CR123A is generally 1400-1500MAH. Nowadays, marketers have falsely high standards for making money, and consumers have no way of knowing this without professional testing. Equipment. We also do this type of battery. The volume of the lithium battery directly determines its capacity. 16340 cannot make more than 800 a of water. There is no darkening process when the power is exhausted. discharge current. If the current is very high, you cannot see this process, so it is normal.
The SMD components on the lithium battery protection board only have Y8 and the rear number 5 prints on it. What model does it represent? Does anyone know the components?
18650 is the most common cylindrical battery cell packaging method, withc a diameter of 18 mm and a length of 65 mm. It is widely used in power banks, laptops, power tools and other fields. Currently, common capacities are 2600 mAh, 2800 mAh and 3000 mAh. LG's new battery cell model is LGABE11865, and the rated capacity in the official PDF is 3,200 mAh. The 11865 lithium battery is the product code of LG and belongs to the category of 18650 lithium batteries. Their length and diameter are the same.
According to the information provided, there are only two screen printed logos: "Y8" and the inverted "5". , and specific details cannot be determined. The chip component model. Usually, the screen-printed logo on electronic components does not directly indicate the model number, but is used to indicate the manufacturer, date, batch and other information of the component.daring.
Therefore, to determine the model of this patch component, more detailed information is needed, such as size, number of pins, color, material, etc. This information can be identified by observing components using a microscope or magnifying glass, or measured and analyzed using component testing instruments.
At the same time, if you know the manufacturer and model of this lithium battery protection board, you can find the relevant technical manual or datasheet and search the component information of the corresponding patch . These manuals usually include detailed information such as circuit diagrams, component lists, parts layout, etc., so that the specific model number of each component can be determined.
In short, to determine the model of the chip component, you need to collect as much informationions as possible, use professional tools to observe and measure, find relevant technical information for reference, and make logical decisions based on this inference and analysis.
