The battery SR927SW has a large amount of electricity, and a multi-motor watch needs to use a battery with a large current, so this battery is suitable for watches running with multiple motors. The battery SR927W has low power and is only suitable for single-motor watches.
2. The water flow is different.
The battery SR927SW has a large amount of electricity, so the discharge current is large. The battery SR927W has a small amount of electricity, so the discharge current is small.
Extended data
Button cell is widely used in various microelectronic products because of its small size, ranging from 4.8mm to 30mm in diameter and from 1.0mm to 7.7mm in thickness. It is generally used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controllers, electric toys, pacemakers, electronic hearing AIDS, counters, cameras, etc.
Button cell is also divided into chemical batteries and physical batteries, of which chemical batteries are the most widely used. They are composed of anode (positive electrode), cathode (negative electrode) and its electrolyte. As shown on the right.
Its outer surface is made of stainless steel, which is used as the positive electrode and the negative electrode is a stainless steel circular cover. The anode and cathode are insulated by a sealing ring, and the sealing ring is made of nylon. The sealing ring not only plays an insulating role, but also can prevent electrolyte from leaking. There are many kinds of button batteries, most of which are named after the materials used, such as silver oxide batteries, lithium batteries and alkaline manganese batteries.
