Button battery is a common battery in our daily life, widely used in a variety of small electronic devices, such as watches, calculators, remote controls and so on. However, due to the wide range of button battery brands and types on the market, how to choose a good quality and long life button battery has become a problem faced by many consumers. This article provides you with some guidelines for selecting button batteries.

There are two main types of button batteries: alkaline button batteries and lithium batteries. Alkaline button batteries are suitable for low-power devices, such as watches, calculators, etc., while lithium batteries are suitable for high-power devices, such as electric toys, remote controls, etc. When purchasing button batteries, select the appropriate battery type according to the device requirements.


The capacity of the battery refers to the ability of the battery to store electrical energy and is measured in milliampere hours (mAh). The capacity is higher, the battery life is longer. When purchasing a button battery, check the capacity of the battery and choose a battery with a higher capacity.

When choosing a button battery, it is recommended to choose a well-known brand. Well-known brands usually have higher technical strength and good product quality, and can provide more reliable products. At the same time, well-known brands often have perfect after-sales service to ensure the rights and interests of consumers.

The shelf life of a button battery refers to the time the battery can maintain a certain capacity under normal storage conditions. Generally speaking, the shelf life of button batteries is 2-3 years. When purchasing button batteries, please pay attention to the production date and shelf life of the battery, and try to choose fresh batteries.


Button batteries have a variety of sizes and shapes, and different devices have different requirements for the size and shape. When purchasing button batteries, please choose the appropriate battery size and shape according to the requirements of the device.


When choosing a button battery, you need to compare the price of the battery. Higher-priced batteries tend to have better performance and longer service life, but that doesn't mean you have to choose the most expensive battery. According to your actual needs and economic ability, choose the battery with the right cost performance.


In short, when choosing a button battery, you need to understand the type of battery, capacity, well-known brand, shelf life, size and shape, and compare the price of the battery. Through the above guide, you can better select the button battery that suits your needs, and provide reliable power protection for your equipment.
