来自市场反馈的有关钮扣电池的 10 大常见问题

A 钮扣电池 (also known as a coin battery) is a small, round primary battery designed for compact electronic devices. Despite their size, button batteries deliver stable voltage, long shelf life, and precise energy output.
Huatai manufactures button cell batteries using advanced sealing technology and high-purity raw materials to ensure reliability across global markets.

Button batteries are generally divided into three main categories:
Zinc Air Button Batteries
AG Alkaline Button Batteries
CR Lithium Button Batteries
Each type serves different devices and usage scenarios, and choosing the correct chemistry is critical for performance and safety.

Zinc air button batteries use oxygen from the air as a reactant, giving them extremely high energy density for their size.
Typical applications include:
Hearing aids
Medical hearing devices
Specialized medical instruments
Huatai zinc air button batteries are designed for stable discharge and high consistency, making them suitable for medical-grade supply channels.

AG alkaline button batteries (such as AG1, AG3, AG10, AG13) are among the most widely used button cells worldwide.
Key features include:
稳定的电压输出
Affordable cost
Reliable performance for daily electronics
Common applications:
Watches
计算器
玩具
Laser pointers
Small electronic devices
Huatai AG alkaline button batteries are produced under strict quality control, ensuring long shelf life and reduced leakage risk.

CR lithium button batteries (such as CR2032, CR2025, CR2450) use lithium manganese dioxide chemistry.
Advantages include:
High energy density
保质期长（长达 10 年）
Wide temperature tolerance
CR lithium button batteries are ideal for:
Car key fobs
Motherboards
Smart meters
医疗设备
IoT sensors
Huatai CR lithium button batteries meet international safety and export standards for global markets.

类型 电压 保质期 Best For
