16340 battery

release time:2025-01-03 Hits:     Popular:AG11 battery

The 16340 battery is a cylindrical lithium-ion rechargeable battery with a diameter of 16 mm and a length of 34 mm. This type of battery is widely used in various portable devices due to its small size and moderate capacity, especially in small electronic devices that require higher energy density. The 16340 battery is sometimes also called RCR123A, where "RCR" indicates that it is a rechargeable CR123A battery.
Main features of 16340 battery

Size and capacity:
Size: 16mm diameter, 34mm length.
Capacity: The specific capacity depends on the manufacturer and the specific design of the battery, but the common 16340 lithium-ion battery capacity ranges from about 600mAh to 1500mAh. Some high-capacity versions can reach or even exceed 1800mAh.

Voltage:
The nominal voltage is generally 3.7V, and can reach 4.2V when fully charged. Some special high-voltage versions may reach 3.8V or 4.35V full charge voltage.

Energy density:
Due to their moderate size, 16340 batteries are able to provide high energy density, which means that they can store more energy in a relatively small volume, making them ideal for portable devices.

Cycle life:
Typical lithium-ion batteries can withstand hundreds to thousands of charge and discharge cycles, depending on usage conditions and maintenance. High-quality 16340 batteries generally have a long cycle life.

Safety:
Modern lithium-ion batteries usually have built-in protection circuits to prevent overcharging, over-discharging, short circuits, etc., which improves the safety of use. In addition, many high-quality 16340 batteries also use more advanced safety features such as thermal protection and explosion-proof design.

Shape flexibility:
The cylindrical design makes this battery easy to manufacture and integrate into various devices, and can provide good mechanical stability when multiple batteries are combined.

Application areas

Portable lighting equipment: such as flashlights, headlights, etc., which require high power output and long-term operation.

Outdoor sports equipment: such as GPS trackers, walkie-talkies, etc., require a stable and reliable power supply.
Medical equipment: such as portable blood glucose meters, pulse oximeters, etc., require long-term stable power support.
Smart home devices: such as smart locks, security cameras, etc., require reliable power support.
Drones and other small aircraft: provide enough energy to support flight control and other functions.
Portable audio devices: such as Bluetooth headsets, portable speakers, etc., need to be lightweight and have a long battery life.

Usage suggestions

Choose a reliable brand: Try to choose batteries from well-known brands when purchasing to ensure performance and safety.
Follow the correct charging method: Use original or compatible chargers to charge, avoid overcharging or discharging. Do not mix batteries of different brands or models.
Pay attention to the storage environment: It should be stored in a dry and cool place, avoiding high temperature and high humidity environments to avoid affecting battery performance.
Check the battery status regularly: Even if the device is not used frequently, it should be checked regularly and replaced as needed to prevent leakage from damaging the device.
Dispose of used batteries properly: Dispose of used batteries properly in accordance with local regulations to avoid environmental pollution.

Alternative options

If you need a battery with different specifications or characteristics, here are some common alternatives to consider:

Larger capacity lithium-ion batteries: If your application requires longer battery life, you can choose a battery of the same size but with a higher capacity.
Other types of cylindrical batteries: Such as 14500, 18650, etc., although larger in size, have a correspondingly increased capacity, which is suitable for applications that are not space-sensitive.
Polymer lithium batteries: If your device allows the use of non-cylindrical batteries, you can consider using polymer lithium batteries of the same capacity level, which are usually thinner and lighter.

Considerations

Match device requirements: Make sure the selected battery is fully compatible with the device, especially in terms of voltage and physical size.
Risk of mixing: Do not mix old and new batteries or different types of batteries (such as lithium-ion and nickel-metal hydride) to avoid device damage or safety hazards.
Protection circuits: Many lithium-ion batteries have built-in protection circuits to prevent overcharging, over-discharging, and short circuits. It is important to ensure that these protection mechanisms work properly.

Summary

16340 batteries are an ideal choice for many devices that require long-term operation or high power output due to their small size and moderate capacity. Understanding their characteristics and how to use and maintain them properly can help you better manage and extend the life of these devices. If you have questions or need further assistance, please consult a professional or refer to the user manual of the relevant product.
