Product Details
The GEB 502535 3.7V 450mAh Lithium Polymer (LiPo) Battery Cell (5×25×35mm) is a compact, high-efficiency lithium polymer pouch cell delivering a verified 3.7V nominal working voltage and 450mAh rated capacity (1.665Wh total energy). Designed with an ultra-thin 5.0mm profile and advanced micro-stacked electrode sheets, this cell exhibits low AC internal impedance (≤ 45–55 mΩ) and supports steady 1.0C continuous discharge (450mA) with 2.0C peak pulse output (900mA ≤ 5s). It is ideal for compact handheld electronics, medical sensors, miniature asset tracking tags, and portable telemetry badges where minimal enclosure thickness is paramount. Engineers must allocate an 8%–10% thickness expansion tolerance in product casings and ensure CC/CV charging regulation does not exceed 4.20V.
Product Overview
The GEB 502535 3.7V 450mAh Lithium Polymer Battery Cell delivers stable energy density and proven cycling reliability for compact commercial and industrial electronics. Featuring physical dimensions of 5.0 × 25.0 × 35.0 mm (±0.3mm) and a lightweight construction of Approx. 9.8g ± 0.5g, it is engineered for devices with strict z-height constraints. Typical applications include handheld GPS navigators, portable patient monitors, smart security badges, wireless remote sensors, and wearable IoT devices. The cell can be supplied with bare nickel tabs or configured with a miniature protection circuit module (PCM), custom wire leads, and specified connector plugs.
