Product Details
The GEB 651235 3.7V 200mAh Lithium Polymer (LiPo) Battery Cell (6.5×12×35mm) is an ultra-compact, high-energy-density pouch cell engineered for micro-wearables, smart eyewear, and miniature medical instrumentation. Delivering a verified 3.7V nominal voltage and 200mAh rated capacity (0.74Wh energy content), this cell features an advanced aluminum laminated barrier pouch that minimizes thickness while maximizing volumetric efficiency. With a calibrated mass of just 4.5g (±0.3g), an internal impedance of ≤ 80–120 mΩ, and standard 1.0C continuous discharge capability (200mA), it provides stable discharge voltage curves across diverse operational temperatures. Designers should confirm compartment dimensions (6.5 × 12.0 × 35.0 mm) and specify lead wire terminations (bare nickel tabs or JST/Molex micro connectors with integrated PCM).
Product Overview
The GEB 651235 3.7V 200mAh Lithium Polymer Battery Cell is engineered to meet the demanding spatial and weight constraints of next-generation portable electronics. Featuring a 3.7V nominal operating voltage and 200mAh rated capacity (0.74Wh energy), this pouch cell utilizes precision-coated cobalt/NCM cathode formulations to achieve high energy density in an ultra-slim footprint. With physical dimensions of 6.5 ± 0.3 mm × 12.0 ± 0.3 mm × 35.0 ± 0.5 mm and a featherweight unit mass of Approx. 4.5g ± 0.3g, it is optimized for AR/VR smart glasses, biometric tracking rings, handheld medical diagnostic pens, and Bluetooth audio transmitters. Factory-installed Protection Circuit Modules (PCM) prevent overcharge, over-discharge, and short circuits.
