Buckle battery with excellent volume advantages and product cost performance and service life of the outstanding performance, and can win the praise of the public, in daily life buckle battery has also been widely used, such as: car keys, TWS headphones, smart watches, etc., so, then about the knowledge of the buckle battery, how much do you know, such as everyone daily replacement of the button battery will look at the positive and negative poles of the button battery?

How to view the positive and negative poles of the clip battery
1, the positive and negative poles of the buckle battery, look at the + sign, the + sign indicates the positive pole, the -sign indicates the negative pole, and one side of the buckle battery will directly mark the + sign, then this side is the positive pole, and vice versa is the negative pole.
2. Generally speaking, the buckle battery will have a relatively flat and smooth side and a raised other side. On this smooth side, the model of the battery itself, the manufacturer and the voltage at which the battery operates are printed, and the button battery is marked with +, which represents the positive electrode of the battery, then this side is the positive electrode of the battery. In most cases, the flat, smooth side of the clip cell battery is the positive electrode. Correspondingly, the other side is the negative electrode of the battery.
3, the positive and negative poles of the buckle battery, look at the model, the buckle battery is marked by the model, as shown in the figure, there are signs such as the model, voltage, negative electrode, etc., then it is the negative pole, and the positive pole is not marked.

4, the positive and negative poles of the buckle battery, look at the surface shape, if you look carefully, we can find that the front and back of the buckle battery are not the same shape, one side is flat, the other side is the arc surface, the surface is flat is the positive pole, and the arc surface is the negative pole.
5, the positive and negative poles of the buckle battery, the most special thing about the concave and convex point buckle battery is that one side is all concave and convex, and the concave and convex points are the negative poles, and the other side is smooth is the positive pole.
6. Multimeter measurement and discrimination can also be used:
(1) Open DC DC voltage file.
(2) Use the red and black pens of the multimeter to contact the two sides of the buckle battery separately.
(3) When the display voltage value is positive, the multimeter red meter pen is connected to the positive pole, and the black meter pen is connected to the negative electrode.
(4) When the display voltage value is negative, the black meter pen of the multimeter is connected to the positive pole, and the red meter pen is connected to the negative electrode.
The above is how to view the positive and negative methods of the buckle battery, Grepp as a professional button battery R & D and manufacturing manufacturers, Grepp button battery using laminated production process is different from the traditional winding technology production process, while Grepp to help downstream customers avoid infringement risks, Grepp accelerated the construction of battery intellectual property protection system, the company has applied for 74 button battery related patents, obtained 42 authorizations, its production of GRP1254, GRP1054 buckle battery is widely loved by customers, It is widely used in TWS headsets, car smart keys and other fields!
