Portable Health Monitoring Devices

The 502045 450mAh lithium polymer battery may be evaluated for compatible portable health monitoring equipment requiring a 3.7V rechargeable power source. Device compatibility must be checked against operating current, charging requirements and available installation space.

Smart Fitness Wearables

Wearable devices require careful battery selection to balance capacity, thickness, weight and operating time. The 502045 pouch cell can be considered where its verified dimensions and electrical characteristics meet the product design.

Compact GPS Tracking Devices

GPS tracking equipment may require rechargeable batteries capable of supporting standby operation and periodic current peaks during communication. The 502045 battery should be evaluated according to the device's peak current, temperature range and runtime requirements.

Smart Home Electronic Controls

Selected portable or backup-powered smart home control modules may use compact rechargeable pouch cells. The battery configuration should be verified against power demand, charging circuitry and operating conditions.

Wireless Audio Accessories

Wireless audio products often have strict mechanical and electrical requirements. The 502045 battery may be considered for compatible designs after confirming battery dimensions, charging characteristics and load current.

Selecting the Right 502045 450mAh Battery

Choosing a rechargeable lithium polymer battery requires matching the cell's electrical and mechanical characteristics with the device's requirements.

The 502045 battery has a nominal voltage of 3.7V and a rated capacity of 450mAh. However, these two values alone are not sufficient to determine whether the cell is suitable for a particular device.

Electrical Compatibility

Before selecting the battery, check the device's normal operating voltage, continuous current, peak current and charging circuit requirements.

Battery capacity affects potential operating time, while allowable discharge current determines whether the cell can safely support the intended load. The actual discharge characteristics must be confirmed with the product datasheet.

Mechanical Integration

For compact electronic products, battery dimensions and installation clearance are essential.

Customers should verify the approved cell drawing, dimensional tolerances, lead wire direction and connector arrangement before finalizing the device enclosure.

Protection and Charging Requirements

Rechargeable lithium batteries require compatible charging control and appropriate protection measures.

The availability of an integrated protection circuit depends on the supplied battery configuration. Device manufacturers should verify overcharge, overdischarge, overcurrent and short-circuit protection requirements during engineering evaluation.

OEM/ODM Lithium Battery Manufacturing

Mingyu Energy provides manufacturing and technical support for customized rechargeable lithium battery projects.

Depending on technical feasibility, customization requirements may include:

Battery selection and capacity requirements
Cell dimensions and mechanical integration
Connector type and lead wire configuration
Protection circuit requirements
Charging and discharge specifications
Product documentation and testing requirements

Customers are encouraged to provide their target application, battery compartment dimensions, estimated order volume and other relevant technical information.

Quality Control and Technical Documentation

Battery quality should be evaluated through appropriate manufacturing controls, inspection procedures and product testing.

For international projects, customers may request applicable technical documents, battery specifications and compliance information.

The availability and validity of certificates or test reports must be confirmed for the specific battery model and supplied configuration.
