Product Details
The GEB 221212 3.7V 10mAh Ultra-Thin Micro LiPo Battery Cell (2.2×12×12mm) is an ultra-miniature Grade-A Lithium Polymer pouch cell engineered for micro-scale electronic devices, delivering 3.7V nominal operating voltage and 10mAh rated capacity (0.037Wh energy content). Formed in an ultra-compact square pouch measuring just 2.2mm in thickness by 12.0mm by 12.0mm with a featherweight mass of approximately 0.5g, it delivers clean, stable DC output for extreme space-restricted wearable and biomedical hardware. Supporting 1.0C continuous discharge (10mA) and peak pulses up to 3.0C (30mA), it is optimized for wearable fitness sensors, in-ear hearing aids, true wireless earbud telemetry, and micro IoT sensor beacons. Designers should accommodate micro-soldering temperature profiles (≤ 280°C for ≤ 3s on nickel tabs) and incorporate PCM protection.
Product Overview
The GEB 221212 3.7V 10mAh Ultra-Thin Micro LiPo Battery Cell (2.2×12×12mm) pushes the boundaries of volumetric miniaturization. With calibrated physical dimensions of 2.2 ± 0.2 mm × 12.0 ± 0.3 mm × 12.0 ± 0.3 mm and a featherweight mass of Approx. 0.5g ± 0.1g, it provides high energy density in a sub-gram package. Utilizing high-purity cobalt-based active materials and precision micro-laser tab welding, it is specifically deployed in smart finger rings, compact hearing assistance devices, biometric ear sensors, covert tracking tags, and implantable sensor telemetry.
