There are five types of watch batteries, namely lithium batteries, silver oxide batteries, silver peroxide batteries, solar batteries and lithium batteries. mercury oxide.
Lithium batteries mainly use metallic lithium as the negative electrode. They have the characteristics of high voltage, generally 3V, low self-discharge rate and long storage life. The silver oxide battery voltage is 1.55V, which is the most commonly used battery in quartz watches. It has high energy density and stability and has no environmental pollution. Silver peroxide battery, also known as divalent silver battery, has a voltage of 1.55V. It has high capacity but low voltage stability.
Solar cells can convert light energy into electrical energy. The voltage of the carbon oxide batterymercury is about 1.35 V. It is the first watch battery developed. It is rarely used due to environmental pollution.
Monitor battery life
Normally, the life of a new battery is generally two years. But this happens under normal conditions of use. If the inside of the watch becomes wet or the hands jump too quickly, the battery life will naturally be shortened. This period is usually a year and a half. For some electronic watches, if the user often makes phone calls or sends messages, these will consume a lot of power and therefore the battery life will be very short.
In addition, there are better quality batteries, which often last for several years. It mainly depends on the type of watch you are buying.
There are 5 battery modelss for watches. Watch battery models are mainly divided into five types, namely lithium batteries, silver oxide batteries, solar cells and mercury oxide batteries. Each of these five types of batteries has its own advantages and disadvantages. When replacing a watch battery, you should choose based on the type of watch.
Characteristics of watch batteries
Lithium batteries use lithium metal as the negative electrode and have high voltage (generally 3V), low self-discharge rate and long life. the duration of the conversation. The silver oxide battery, with a voltage of 1.55 V, is the most commonly used battery in quartz watches. It has high energy density and stability and has no environmental pollution.
Silver peroxide battery, also known as divalent silver battery, voltage 1:55V. It has a capacityhigh but poor voltage stability. Solar cells can convert light energy into electrical energy. Mercury oxide battery, the voltage is 1:35 V. This is the first watch battery developed. Due to environmental pollution, it is rarely used.
