Product Details
The GEB 352028 3.7V 180mAh Lithium Polymer (LiPo) Battery Cell (3.5×20×28mm) is an ultra-compact, high-energy-density flexible pouch lithium polymer cell engineered for space-constrained electronics. Delivering a verified 3.7V nominal working voltage and 180mAh rated capacity (0.666Wh energy), this ultra-thin pouch cell features high-precision multi-layer stacking technology and low internal impedance (≤ 90 mΩ). Encapsulated in an ultra-slim aluminum-plastic composite pouch, it provides high volumetric efficiency for smart glasses, Bluetooth audio headsets, wearable medical sensors, and miniature IoT tracking nodes while maintaining stable thermal expansion control. Engineers must ensure an 8%–10% thickness swelling allowance in device enclosures across the cell’s cyclic life.
Product Overview
The GEB 352028 3.7V 180mAh Lithium Polymer (LiPo) Battery Cell (3.5×20×28mm) is a Grade-A flexible pouch lithium polymer cell developed specifically for ultra-compact electronic hardware. Delivering 3.7V nominal voltage and 180mAh rated capacity, this cell utilizes advanced high-energy-density stacking technology, ultra-pure electrolyte formulation, and low internal impedance. Featuring physical dimensions of 3.5 × 20.0 × 28.0 mm (±0.3mm) and a calibrated unit weight of Approx. 4.2g ± 0.3g, it is optimized for smart eyewear, handheld barcode scanners, POS micro-terminals, wireless headsets, and wearable medical diagnostic devices.
