Product Details
The GEB 18650 3.6V 2400mAh Cylindrical Lithium-ion (Li-ion) Battery Cell (18×65mm) is an industrial-duty cylindrical cell providing a stable 3.6V nominal plateau and 2,400mAh capacity (8.64Wh). Built inside a heavy-duty nickel-plated steel shell (18.3 × 65.0 mm, ~44.0g net weight), this cell features an internal safety valve and high thermal tolerance (-20°C to +60°C discharge range). Optimized for long operating life (≥800 cycles @ 80% DoD) and steady 1.5C–2.0C continuous load discharge, it is an ideal choice for hazardous environment flashlights, warehouse barcode scanners, two-way radios, and commercial monitoring electronics.
Product Overview
The GEB 18650 3.6V 2400mAh Cylindrical Lithium-ion (Li-ion) Battery Cell (18×65mm) is a robust, field-tested cylindrical lithium cell engineered for dependable daily cycling in rugged commercial equipment. Offering 3.6V nominal voltage and 2400mAh rated capacity (8.64Wh total energy), it combines automated electrode winding with an explosion-proof safety vent and high-purity electrolyte. With physical dimensions of Ø 18.3 ± 0.2 mm × H 65.0 ± 0.3 mm and a net weight of Approx. 44.0g ± 1.5g, it is engineered for miners’ cap lamps, intrinsically safe explosion-proof torches, rugged logistics barcode scanners, two-way mobile radios, and smart commercial thermostats. Flat-top cells allow rapid pack welding, while button-top versions provide immediate replacement in industrial equipment battery compartments.
