Product Details

Direct Answer / Engineering Summary

The GEB 3.6V 2000mAh AA Ni-MH Rechargeable Battery Pack (3S Pack for Solar & Backup) is an industrial Nickel-Metal Hydride power pack constructed from three matched AA cylindrical cells in series (3S1P). Providing a verified 3.6V nominal working voltage and 2,000mAh rated capacity (7.2Wh energy), this pack is engineered for high cycle endurance (≥ 500–1,000 cycles under IEC standards) with zero memory effect. Assembled with precision spot-welded nickel tabs, built-in PTC over-current protection, and pre-attached UL1007 wire leads, it delivers dependable standby and cyclic power for solar outdoor lighting, emergency exit signs, remote telemetry sensors, and PCB memory retention.

Engineering Overview

Product Overview

The GEB 3.6V 2000mAh AA Ni-MH Battery Pack offers an inherently safe, environmentally compliant alternative to legacy Nickel-Cadmium (Ni-Cd) packs while delivering more than double the volumetric energy density. Built from Grade-A AA cells (14500 cylindrical size) arranged in an inline flat configuration measuring 43.5 × 14.5 × 50.5 mm and weighing Approx. 85g, it is encased in protective blue PVC heat-shrink tubing. Each string includes an integrated positive temperature coefficient (PTC) thermistor that automatically throttles current under external short-circuit events, resetting once the fault clears.

Engineering & Integration

Integration & Operational Boundary Conditions

Solar Panel Matching & Charging: When deploying in solar garden lighting fixtures, ensure the solar charge controller maintains a trickle charge current of 0.05C–0.1C (100mA–200mA) and prevents overcharge voltage from exceeding 4.50V across the 3S pack.

Over-Discharge Safeguard: Disconnecting loads when pack voltage drops to 3.00V (1.00V/cell) is mandatory. Operating below 2.4V (0.8V/cell) causes cell reversal, venting, and premature failure.

Storage & Self-Discharge: Store in a cool, dry location at 40%–60% state of charge. Ni-MH chemistry maintains an open circuit voltage around 1.25V–1.28V per cell (3.75V–3.85V for 3S pack) when healthy. Refresh every 90–120 days during prolonged warehouse storage.
