14430 lithium ion battery is a rechargeable cylindrical battery commonly used in compact electronic devices and specialized applications. Its name is based on its dimensions, similar to other lithium-ion batteries (e.g., 18650, 21700): 14 refers to the diameter (14 mm), and 430 refers to the length (43 mm).

Common Applications
Due to their compact size, rechargeability, and high energy density, 14430 batteries are commonly used in solar garden lights, flashlights, medical equipment, small portable electronic devices, toys, consumer electronics, electric toothbrushes, and DIY electronics projects.
They are often chosen as a rechargeable alternative to AA or CR2 batteries when space is limited and higher voltage is required.
Precautions
• Not all devices that use AA batteries support 3.7V lithium batteries. Make sure your device can accept this voltage to avoid damage or safety hazards.
• Only use chargers designed for lithium-ion batteries. Do not use other types of chargers.
• Keep the battery away from high temperatures, humidity, or flammable environments during charging and in a well-ventilated area.
• Disconnect the power cord immediately after the battery is fully charged to avoid prolonged overcharging.
• Do not reverse polarity. Verify polarity during installation.
• Do not plug the battery into a power outlet.
• Do not connect the battery to the positive and negative terminals with metal objects (such as keys, hairpins, necklaces), and do not store the battery with metal objects.
• Do not pierce, strike, throw, or step on the battery to prevent internal short circuits, leakage, or explosion.
• Do not solder the battery yourself or pierce the battery with nails or other sharp objects.
• If the battery becomes hot, smokes, deforms, changes color, or emits an odor, stop using it immediately and remove it from the device.
• Do not place the battery near fire, heaters, or other high-temperature devices.
• Do not use or store the battery in high-temperature environments, such as in a car exposed to the sun or in direct sunlight.
• Do not dispose of the battery in fire, microwave ovens, or water to avoid explosion or combustion.
• If the battery leaks and the electrolyte gets into your eyes, do not rub them. Immediately rinse with clean water and seek medical attention.
• If any abnormality is detected during use or charging, immediately stop use and remove the battery from the device.
