Button cell refers to a battery that looks like a small button. Generally speaking, it has a larger diameter and thinner thickness. Button batteries are divided into cylindrical batteries, square batteries and special-shaped batteries according to their appearance. The size of button batteries usually uses the new numbering method of IEC. The first two digits are the diameter and the last two digits are the thickness. For example, the size of CR2032 is 20 mm in diameter and 3.2 mm in thickness.
Common button batteries include rechargeable and non-rechargeable types. Among them, the charging types include 3.6V rechargeable lithium-ion button batteries (LIR series) and 3V rechargeable lithium-ion button batteries (ML or VL series). Non-rechargeable types include 3V lithium-manganese button batteries (CR series), and 1.5V alkaline zinc-manganese button batteries (LR and SR series).
Button batteries can be divided into chemical batteries and physical batteries, among which chemical batteries are the most widely used. They usually consist of anode (positive electrode), cathode (negative electrode) and electrolyte. The positive electrode of the battery is made of stainless steel, while the negative electrode consists of a stainless steel round cap. There is an insulating sealing ring made of nylon between the positive and negative electrodes. Nylon not only insulates, it also prevents electrolyte leakage. There are many types of button batteries, and their names are mainly based on the materials used, such as silver oxide batteries, lithium batteries, alkaline manganese batteries, etc.
CR2354 is a non-rechargeable 3V lithium coin cell battery with a capacity of 560mAh, designed for small electronic devices requiring low power consumption. It is commonly used in keychains, calculators, digital watches, toys, wearable electronics, medical equipment and CMOS backup batteries, etc. Its annual self-discharge rate is typically in the 1-3% range, giving these batteries a shelf life of at least three to ten years. Due to its lithium manganese dioxide chemistry, CR2354 batteries have a very wide temperature range, typically -30°C to 60°C. Its packaging is made of clear plastic and is airtight to protect the battery, with identification labels, safety warnings and disposal instructions.
Alternative models:
• BR2354
• CR2412
• DL2354
• KL2354
• LM2354
As depicted in the image, the CR2354 battery measures 23mm in width, 5.4mm in height, and weighs just 5.8g. This battery is both compact and lightweight.
1. Excellent heavy load discharge characteristics
2. With 3V high energy density: When the voltage is 3V, the voltage is about twice that of alkaline button batteries and silver oxide button batteries.
3. The discharge characteristics are stable and maintain low internal resistance and high operating voltage throughout the discharge process: Due to the use of electrolyte with high conductivity, the battery has low internal resistance and stable operating voltage. No matter under room temperature, high temperature or low temperature conditions, the working voltage changes little and can provide stable power supply for the equipment.
4. Especially suitable for memory and RTC backup power: maintain stable operating voltage for a long time under low load conditions.
5. Excellent leak-proof performance and excellent storage characteristics: Due to the use of leak-proof organic electrolyte, the leak-proof performance of this battery is better than other alkaline electrolyte batteries. In addition, by using a highly sealed sealing structure and fine sealant treatment, the battery's self-discharge rate can be reduced to only 1% per year.

• BR2354 batteries are typically used in devices that require longer life and lower current requirements, such as remote controls, sensors, and small wireless devices.
• LIR2354 batteries are commonly used in devices that require higher voltage and performance, such as some medical equipment, handheld electronic devices, and electronic cameras.
CR2354 is a mercury-free 1HF/1HE lithium battery that uses conventional charging equipment for charging. When charging, it is recommended that the charging voltage is 3.6 to 3.8V and the charging current is 0.1 to 1.0A. Be careful not to overcharge or overdischarge, as this will cause damage to the battery. At the same time, there are certain safety risks when charging the battery. In order to prevent accidents, we should avoid placing the battery in an environment with high temperature, humidity, direct sunlight, and place the battery within the reach of children and pets.
When the CR2354 battery is not used for a long time, we need to remove the battery from the device and store it in a low temperature and low humidity environment. If the battery terminals become dirty, wipe them with a dry cloth before use. Batteries should be used and stored away from static electricity, and kept in an environment of 10°C to 25°C (not exceeding 30°C) and a humidity of 45% to 75%.
