![]() Its GRP1254 and GRP1054 button batteries are welcome with customers and widely used in TWS headphones, smart car keys, and other fields! In general, either look at the signs ("+, -") or look at the shapes.Īs a professional manufacturer of button battery R&D and manufacturing and can provide customized services, Grepow uses a lamination production process that is different from the traditional winding technology. Meanwhile, to help downstream customers avoid the risk of infringement, Grepow has accelerated the construction of a battery intellectual property protection system and has applied for 74 patents related to buckling batteries and obtained 42 authorizations. The above are 5 ways how to check the positive and negative poles of a button battery. (4) When the displayed voltage value is negative, the black pen of the multimeter is connected to the positive pole, and the red pen is connected to the negative pole. (3) When the displayed voltage value is positive, the red test lead of the multimeter is connected to the positive electrode, and the black test lead is connected to the negative electrode. (2) Use the red and black test pens of the multimeter to contact the two sides of the button battery respectively. The positive and negative electrodes of the button battery, the most special feature of the button battery are that one side is full of concave and convex points, the one with the concave and convex points is the negative electrode the other side is smooth is the positive electrode. One side is flat, the other side is curved, and the surface is flat. ![]() If you look carefully, we can find that the front and back of the button battery are of different shapes. The positive and negative electrodes of the button battery, look at the shape of the surface. Most button batteries have at least one side marked with a positive and negative sign "+" or "-" of course, some are not marked, what should I do? The following continues to introduce 3 methods to distinguish the positive and negative of the button battery. Grepow Rechargeable Button-cell battery (Coin cell ) The positive and negative poles of the button battery, see the model, the button battery is marked with the model, as shown in the figure, there are signs such as model, voltage, negative pole, etc., then it is the negative pole, otherwise, the positive pole is not marked. Then correspondingly, the other side is the negative electrode of the battery. In most cases, the flat, smooth side of a coin cell battery is the positive side. The button battery marked with + means the positive electrode of the battery, and this side is the positive electrode of the battery. ![]() On the smooth side, the model of the battery itself, the manufacturer, and the operating voltage of the battery will be printed. ![]() Generally speaking, the button battery will have a relatively flat and smooth side and a convex side. Positive and negative terminals of Button cell batteries ![]() One side of the button battery is directly marked with the + sign, then this side is the positive electrode, and the other side is the negative electrode. How much do you know about button batteries? Do you check the positive and negative poles of the button battery when you replace the button battery every day?įor the positive and negative electrodes of the button battery, look at the + sign, the + sign indicates the positive electrode, and the - sign indicates the negative electrode. Button batteries have also been widely used in daily life, such as car keys, TWS headphones, smartwatches, etc. The button battery has won the praise of the public with its excellent volume advantage, high-cost performance, and excellent service life. ![]()
