302025 3.7V 120mAh Lithium Polymer Battery

The 302025 3.7V 120mAh Lithium Polymer Battery from Vcell Power is a high-performance rechargeable lithium polymer cell for space-sensitive portable devices. As a national high-tech enterprise with over 20 years of R&D experience, this battery not only passes ISO9001 quality management but also, with its card-slim profile and excellent cycle stability, perfectly solves the design conflict between "small size" and "long battery life" for micro electronics -- an ideal power partner for OEM/ODM customers.

Core Advantages

Vcell Power condenses the technical strengths of this model into three core advantages, providing comprehensive protection for your products in terms of physical form, service life, and electrical safety.

Ultra-Thin: 3.2mm Breaks Space Constraints

Ultra-compact dimensions -- The 302025 3.7V 120mAh Lithium Polymer Battery achieves a total thickness (including PCM) of only 3.2mm, with a weight of approximately 4g, enabling seamless integration into space-limited devices.

Design freedom -- Ideal for smart remotes, anti-loss trackers, and Bluetooth earbuds, this battery eliminates the size constraints of cylindrical cells and unlocks more creative industrial design possibilities.

Stacked lamination process -- Utilizes advanced lithium polymer pouch technology to maximize energy density within an ultra-slim profile.

Long Cycle Life: Rock-Solid Reliability

Far exceeds industry average -- The 302025 3.7V 120mAh Lithium Polymer Battery demonstrates cycle stability well above the typical market level of 300-500 cycles, as verified by official aging tests.

Lower after-sales costs -- Extended cycle life significantly reduces post-warranty battery replacement rates, protecting your brand reputation and customer satisfaction.

Consistent long-term performance -- Devices powered by this cell maintain a strong "heart" throughout their entire lifecycle, ensuring reliable operation over years of use.

Built-in Multi-Protection: Safety Guardian

Four-layer protection -- An integrated high-precision PCM provides overcharge, over-discharge, overcurrent, and short circuit protection for complete electrical safety.

Stable under extreme temperatures -- The 302025 3.7V 120mAh Lithium Polymer Battery operates reliably from -20°C to 60°C (discharge) without swelling or leakage, thanks to its solid electrolyte design.

ISO9001-certified manufacturing -- Every cell is produced under strict quality control to eliminate micro-level instabilities that could lead to failures in miniature packages.

Diverse Application Scenarios

The ultra-thin and lightweight characteristics make this battery model perfectly suited for multiple application fields with strict space and weight limitations:

Smart Wearables -- Provides tailor-made invisible energy for smart glasses, Bluetooth earbuds, health monitoring watches, and activity trackers.

IoT & Micro Sensing -- Widely used in door/window magnetic sensors, temperature/humidity probes, and various industrial IoT tags for long-lasting, low-power maintenance‑free standby.

Portable Audio Recording -- For voice recorders and portable conference microphones, ensuring stable voltage output alongside high capacity.
