Common Button Cell Battery Models: Types, Specifications, and Applications

Button cells, also known as coin cells, are batteries shaped like small buttons. They are generally larger in diameter and thinner (compared to cylindrical batteries like AA batteries). Button cells are categorized by their shape; corresponding battery types include cylindrical, square, and irregularly shaped batteries. They are used in many electronic fields, making our lives more convenient and reducing the environmental pollution caused by batteries. However, with many button cell manufacturers and a wide variety of products, many consumers end up making purchases blindly.

With the proliferation of various electronic products in our lives, besides appliances that can be directly powered by electricity, some electronic products rely on batteries to operate, such as watches and calculators. Button batteries are also a common type of battery, widely used in many products due to their small size, resembling a button. What are some of the button battery models we commonly encounter in our daily lives? When choosing and purchasing button batteries, it is essential to select the appropriate model based on your device . Today, I will list some common button battery models for you.

• Button Battery Introduction

Button batteries are generally available in two types: rechargeable and non-rechargeable. Rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series) and 3V rechargeable lithium-ion button batteries (ML or VL series); non-rechargeable ones include 3V lithium manganese button batteries (CR series) and 1.5V alkaline zinc manganese button batteries (LR and SR series).

The CR2032 button cell battery is mainly used in electronic scales, watches, battery remote controls, etc. It uses mercury-free lithium battery material, which is more environmentally friendly and reduces pollution to water, soil and our lives. It also has a strong leak-proof design, is pollution-free and safer. Lithium batteries are more stable and reliable than ordinary batteries, and have a longer discharge time.

Another type of button battery is the LR44, with a voltage of 1.5V. It is commonly used in toys or calipers. It uses new-generation materials and high-quality cells, resulting in longer battery life and very low capacity loss during use. However, this type of battery must be connected according to the correct positive and negative terminals. Reversed connection or short circuit can cause an explosion. To ensure battery life, new batteries should not be used simultaneously with old batteries. The moisture-proof, sealed plastic packaging allows for convenient use, and when not in use, it provides better moisture protection than cardboard packaging.

The LIR2032 button battery, although also used in remote control motherboards, hand-cranked flashlights, badges, etc., is rechargeable and reusable. It costs 2 yuan per battery and can be charged and discharged more than 500 times. It can usually be charged in two or three hours. The voltage of this button battery is 3.6V.

• How to read the model number of a button battery

The letters preceding the model name of a button battery indicate the type of battery, and the numbers indicate the size; the first two digits represent the diameter, and the last two digits represent the thickness.

• Common and typical models

6F22(9V), 4F22(6V), 15F20(22.5V), 10A(9V), 11A(6V), 23A(12V), 25A(9V), 26A(6V), 27A(12), 476A(6V), 120H7D(8.4V), 2X625A(3V), etc.

• Button battery applications

Button batteries are widely used in various microelectronic products due to their small size. Their diameter ranges from 4.8mm to 30mm and their thickness from 1.0mm to 7.7mm. They are generally used as backup power for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc.
