Introduction
When I evaluate a rechargeable lithium polymer battery for an OEM project, I do not look at capacity alone. For many commercial products, the battery must also fit the available space, meet electrical requirements, pass relevant safety evaluations, and provide documentation that can support the customer's compliance process.
That is why I am highlighting our AS502248 3.7V 500mAh lithium polymer battery cell in this article.
The AS502248 is a compact rechargeable LiPo cell with a nominal voltage of 3.7V and a typical capacity of 500mAh. Its compact cylindrical-free pouch construction allows the battery geometry to be considered more flexibly during product design.
More importantly for OEM customers, this cell has documentation covering UL1642, CB, CCC, KC, CE and UN38.3. This documentation gives customers a clearer starting point when evaluating the battery for new products, supplier qualification and regional compliance requirements.

Why Certification Matters for OEM Battery Selection
From my experience working with OEM battery projects, certification should not be treated as a substitute for engineering validation.
A battery can have the appropriate certification documentation and still be unsuitable for a particular device if its dimensions, current capability, connector, protection circuit, charging profile or operating temperature do not match the product.
When I evaluate a battery for an OEM application, I normally look at:
- Available battery compartment
- Required capacity
- Maximum charge current
- Maximum discharge current
- Operating temperature
- Charging IC compatibility
- Protection circuit requirements
- Connector and wire configuration
- Required certification
- Transportation documentation
Typical Applications for a 3.7V 500mAh LiPo Battery
A 3.7V 500mAh LiPo cell can be considered for many compact electronic applications, including:
- Wearable electronics
- Portable consumer electronics
- GPS and tracking devices
- IoT devices
- Smart sensors
- Beauty and personal-care devices
- Portable medical electronics
- Handheld instruments
- Small industrial electronics
- Smart home products
The final battery selection should always be based on the device's electrical load, mechanical space, charging system and required safety architecture.
