Product Details
The GEB 1.2V 2000mAh Ni-Cd Sub-C Industrial High-Drain Rechargeable Battery Cell is a rugged Nickel-Cadmium (Ni-Cd) cylindrical power cell engineered for extreme-duty commercial hardware and power tools. Delivering a verified 1.2V nominal working voltage and 2,000mAh rated capacity (2.4Wh energy), this Sub-C cell provides a sustained 10C continuous discharge rating (20A continuous) and 15C pulse capability (30A ≤ 5s). Built with heavy-duty sintered electrodes and an integrated resealable mechanical safety vent, it delivers exceptional overcharge and deep-discharge abuse tolerance and reliable operation across harsh ambient temperatures from -20°C to +65°C. System designers should calibrate charger cutoffs for constant-current timed charging (0.1C, 14–16h) or -ΔV (negative delta voltage) fast-charge termination.
Product Overview
The GEB 1.2V 2000mAh Ni-Cd Sub-C Industrial High-Drain Rechargeable Battery Cell is an engineered electrochemical solution designed for high-drain cyclic duty where standard lithium chemistries may be limited by thermal extremes or abuse constraints. Featuring a 1.2V nominal operating voltage and 2000mAh rated capacity, this industrial cell withstands aggressive 20A continuous discharge (10C rate) while maintaining high voltage plateau stability. Encased in a heavy-duty nickel-plated steel canister with an insulating PVC heat-shrink sleeve and integrated resealable pressure vent, it measures Ø 23.0 ± 0.2 mm × H 43.0 ± 0.3 mm (Standard Sub-C form factor) and weighs Approx. 48.0g ± 1.5g. Optimized for cordless industrial power tool packs (drills, impact wrenches), emergency lighting luminaires, automated guided equipment, and harsh outdoor field instruments.
