Modern smart devices continue to become smaller, creating higher requirements for battery size, weight and integration flexibility. The 08120 3.8V 60mAh rechargeable Pouch Polymer Li-ion battery is designed for applications where installation space is limited but stable power output is still required.
Compared with traditional rigid battery structures, the polymer pouch design uses an aluminum-plastic composite package, allowing more flexibility in product layout and reducing unnecessary weight. The compact form factor makes it easier for engineers to integrate the battery into miniature electronic products with restricted internal space.
Yideng develops small-format lithium battery solutions based on customer product requirements, helping manufacturers achieve better balance between device size, runtime and reliability.

The 08120 3.8V 60mAh rechargeable Pouch Polymer Li-ion battery adopts a 3.8V voltage platform with a 60mAh capacity, providing consistent energy output for low-power intelligent devices.
Through controlled manufacturing processes, the battery maintains stable capacity performance and low self-discharge characteristics during storage and operation. The lightweight structure helps reduce the overall weight of end products while maintaining reliable rechargeable performance.
With a cycle life of more than 300 charge and discharge cycles under standard conditions, this miniature Li-ion polymer battery is suitable for products requiring repeated charging and long-term usage.
Different electronic products require different connection designs. Yideng provides customized battery integration services to help customers match the battery with their product structure.
Available customization options include:
- Customized battery tabs
- Wire lead selection
- Connector configuration
- Protection circuit board matching
- Battery size adjustment according to product requirements
For manufacturers developing wearable devices, smart sensors and miniature electronics, Yideng can provide battery solutions from sample verification to mass production.
The polymer lithium battery structure provides advantages that are especially valuable for compact electronic products.
The aluminum-plastic composite packaging reduces battery weight while allowing thinner and more flexible product designs. Unlike traditional metal-cased cells, the pouch structure provides greater freedom for shape optimization and connection arrangement.
For designers working on small intelligent devices, this structure helps simplify internal layout and improves the possibility of integrating the battery into customized product designs.
Yideng supports customers throughout the battery development process, from early prototype testing to continuous production supply.
After receiving product specifications, our engineering team can assist with battery selection, connection design and sample preparation. Customers can verify battery performance, installation compatibility and product operation before moving to larger production orders.
Our customization service covers battery configuration, wiring solutions and protection circuit matching, helping customers shorten development cycles and improve product reliability.
A1: Yes. We offer OEM/ODM service. We can customise PCM, wire length and assemble different pin connectors according to your device demands.
A2: Our some batteries have passed UN38.3, RoHS, CE, BIS, KC, PSE, UL1642 and UL2054 Certifications, we support applying for extra certifications as required.
A3: Stock standard models support small trial orders. For fully customized cells with special size, wiring and protection circuits, the MOQ depends on technical requirements.
A4: Custom 10 ~ 20pcs samples take 3 ~ 7 working days. Mass production needs 18 – 30 days after sample confirmation. We will arrange priority production for urgent orders if schedule permits.
A5: Yes. All our batteries meet UN38.3 shipping standards. We provide complete DGM air and sea report.
A6: Under proper charging and usage conditions, our lipo cells achieve 300 charge cycles. Matching a suitable protection circuit board will effectively avoid overcharge and overdischarge to extend battery lifespan.
