Product Details
The GEB 742045 3.7V 630mAh Lithium Polymer (LiPo) Battery Cell (7.4×20×45mm) is an ultra-compact pouch cell specifically optimized for portable metal detectors, security inspection wands, and precision radio-frequency diagnostic devices. Delivering 3.7V nominal voltage and 630mAh rated capacity (2.33Wh energy content), this cell utilizes non-magnetic nickel tabs and ultra-low internal impedance (≤ 40–50 mΩ) to prevent electromagnetic interference with sensitive search coils. With continuous 1.0C discharge capability (630mA) and 2.0C pulse support (1260mA ≤ 5s), it ensures consistent operational voltage throughout demanding screening shifts. System designers should allocate 8%–10% thickness expansion margin in the battery compartment and verify connector specifications prior to mass assembly.
Product Overview
The GEB 742045 3.7V 630mAh Lithium Polymer Battery Cell is engineered to deliver reliable, long-cycle energy within space-constrained handheld electronics. Built with high-energy-density stacked electrodes and flexible multi-layer aluminum laminated film packaging, the cell measures 7.4 × 20.0 × 45.0 mm (±0.3mm) and weighs approximately 14.2g ± 0.8g. Designed for security walk-through hand wands, underground pinpointing probes, compact asset trackers, and medical diagnostic instruments, the cell can be ordered with bare solder tabs or equipped with a micro protection circuit module (PCM) featuring pre-crimped JST, Molex, or custom wire leads.
