How to fix the cr927 button battery to the pcb board? This kind of battery needs a battery holder to be fixed, so when you draw the PCB board, you must first put a battery holder package.

Can quartz watch batteries LR920 and cR927 be used in common?

LR920 is an alkaline battery, also known as AG6 or Type 371 battery, commonly found in some small electronic devices and watches. cR927 is a silver oxide battery, also known as SR57 or 399 battery, which is commonly found in some high-end watches and electronic equipment. Although the two batteries may be similar in shape and size, they may differ in parameters such as electrochemical properties and voltage. Therefore, LR920 and cR927 batteries are not universal and cannot be used as substitutes for each other.

In addition to batteries, the maintenance of quartz watches also includes the following aspects: 1. Water resistance: Some quartz watches are waterproof, but not all quartz watches can be used in water. If your quartz watch is not water resistant, try to avoid submerging it in water. If your quartz watch has waterproof function, you should also pay attention to regular replacement of the sealing ring to ensure waterproof performance. 2. Cleaning: The surface of a quartz watch is susceptible to dirt and dust and should be cleaned regularly. You can use a soft cloth to gently wipe the surface, avoid using chemical cleaners or too wet cloth. 3. Avoid vibration: The movement of the quartz watch is very precise, so it should avoid severe vibration and collision, so as not to affect its normal operation. 4. Regular maintenance: If your quartz watch will not be used for a long time, you should take out the battery to prevent battery leakage from affecting the movement. At the same time, it is recommended to send the quartz watch to a professional repair shop for maintenance and maintenance at regular intervals (usually 2-3 years) to ensure its normal operation and service life.
