402030 polymer battery (Polymer Battery), usually refers to a lithium polymer battery (Li-Po or Li-Poly) with a size of 40mm x 20mm x 30mm. This type of battery is widely used in various portable electronic devices and is favored for its lightweight, high energy density and thin design. Lithium polymer battery is an improved form of lithium-ion battery. It uses solid or gel polymer electrolyte instead of liquid electrolyte in traditional lithium-ion battery, which makes the battery safer, lighter and has better shape flexibility.
Main features of 402030 polymer battery
Size and capacity:
Size: 40mm (length) x 20mm (width) x 30mm (thickness), this size is suitable for small electronic products that require compact design.
Capacity: The specific capacity depends on the manufacturer and the specific design of the battery, but the common capacity range is about 500mAh to 1500mAh. For batteries of this size, the larger the capacity, the heavier or thicker it usually means.
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:
Lithium polymer batteries have a high energy density, which means that they can store more energy in a relatively small volume, making them ideal for portable devices.
Cycle life:
A typical lithium polymer battery can withstand hundreds to thousands of charge and discharge cycles, depending on usage conditions and maintenance.
Safety:
Polymer electrolytes reduce the risk of leakage and are less likely to have internal short circuits, making them safer than traditional lithium-ion batteries.
Shape flexibility:
Due to the use of flexible packaging materials (such as aluminum-plastic film), lithium polymer batteries can be customized into different shapes as needed to suit the design requirements of specific products.
Light weight:
Compared with other types of rechargeable batteries, lithium polymer batteries are lighter, which helps reduce the overall weight of the final product.
Application areas
Drones: Provide enough energy to support flight control and other functions.
Smartphones and tablets: Integrated into the device to provide long battery life.
Smart wearable devices: such as smart watches, fitness trackers, etc., these devices usually require very small and light batteries.
RC models: including remote control aircraft, cars, etc., require fast response and high power output.
Portable medical devices: such as blood glucose meters, pulse oximeters, etc., require stable and reliable power supply.
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 the original or compatible charger to charge, and avoid overcharging or discharging.
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, the battery 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, you can consider the following common alternatives:
Larger capacity lithium polymer battery: If your application requires longer battery life, you can choose a battery of the same size but with a higher capacity.
Cylindrical lithium batteries (such as 18650): Although they are larger in size, they also have a correspondingly increased capacity, making them suitable for applications that are not space-sensitive.
Other shapes of lithium polymer batteries: Depending on the needs of the product design, lithium polymer batteries of different shapes and sizes can be selected.
Notes
Match device needs: Make sure the selected battery is fully compatible with the device, especially in terms of voltage and physical size.
Mixing risks: Do not mix old and new batteries or batteries of different types (such as lithium polymer and lithium ion) to avoid device damage or safety hazards.
Protection circuits: Many lithium polymer 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
402030 polymer batteries are ideal for many small electronic devices due to their small size, light weight, and high energy density. 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 help, please consult a professional or refer to the user manual of the relevant product.
Choose the right battery supplier
Evaluate products from multiple suppliers: Compare the technical parameters of 402030 polymer batteries from different suppliers, such as capacity, cycle life, safety certification, etc.
Get samples for testing: Request samples from potential suppliers and conduct comprehensive tests in a lab environment to determine the best battery for your product.
Design optimization
Ensure good heat dissipation design: Considering that lithium polymer batteries are sensitive to temperature, effective heat dissipation measures such as vents or heat sinks should be incorporated into the product design.
Protection circuit integration: Ensure that the battery is equipped with appropriate protection circuits to prevent problems such as overcharging, over-discharging and short circuits.
