Wall clocks generally use carbon batteries.
Wall clocks use carbon batteries to prevent damage to the movement. Carbon batteries are primary batteries in chemical power sources. They are disposable batteries, also called dry batteries. Carbon batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also for various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine.
Please do not use Nanfu’s or rechargeable batteries or high-capacity alkaline batteries, because the capacity is too high and the current is too strong. (Alkaline batteries are 4-5 times the capacity of carbon batteries, and the price is 1.5 times that of carbon batteries. Carbon The battery is suitable for use in low-current electrical appliances, such as quartz clocks, remote controls, and batteries).
