The difference between ordinary dry-cell batteries and silver oxide battery

　　Ordinary dry-cell batteries voltage will be used as decline gradually, and silver oxide battery voltage only near the end of life time, voltage plummeted, this feature to ensure accuracy of quartz watch when there is a lot of benefits. But the problem is not simply by measuring the battery voltage method to judge whether the capacity of the battery is enough, it is said that now is no quick and nondestructive instrument, to do the measurement.

　　Good quality batteries, surface polishing is very bright, logos and letters mark clear, its sides are typed a child of the mother, said the production date. Fake batteries are coarser, mark, and life is very short. Watch battery is famous brand: Switzerland has "RENATA" (it) each cell is independent packing, Japan‘s SEIKO SEIKO, SONY SONY, pine valley, the quality is pretty good. Good to must choose quality quartz watch batteries, inferior battery will often bring harm to watch.
