First: The new model uses a more flexible PP material, which has higher strength and toughness, no longer cracks, and greatly increases the service life. At the same time, the case is processed into a frosted translucent effect, which is less prone to wear and aging.
Second, the mold is designed with a convex fixed card slot, so that the two ends are no longer simply fixed by the precision of the material.
Third, the negative electrode directly uses the exposed negative electrode of the No. 7 battery.
Fourth, the newly designed positive electrode (marked "+") uses an extended pure copper nickel-plated positive hat, which is suitable for electrical appliances with deeper positive electrode slots. At the same time, the touch part between the inside of the adapter tube and the battery is enlarged, which greatly reduces the touch resistance.
No. 7 to No. 5 tube, you can use No. 7 batteries as No. 5 batteries. In daily use, when the No. 5 battery is out of power, and there is a No. 7 battery nearby, this can come in handy; the No. 7 battery is light in weight and can be used in wireless mice and other devices after conversion, with good results.
