WALTON WLED-BTR-CELL-2000MAH 3.7V 2000mAh Lithium-Ion Rechargeable Battery Cell

WALTON WLED-BTR-CELL-2000MAH 3.7V 2000mAh Lithium-Ion Rechargeable Battery Cell

Power emergency lights, portable devices, battery packs, and backup power units with the WALTON WLED-BTR-CELL-2000MAH 3.7V Rechargeable Lithium-Ion Cell. Built with a guaranteed minimum 2000mAh capacity and a low internal impedance of ≤45mΩ, this cell delivers stable power output and efficient energy density.

Operating at a 3.7V nominal voltage, it utilizes a standard CC-CV charging method (4.2V max) and safely discharges down to its 2.7V cut-off limit. Ideal for replacing internal cells in emergency lighting fixtures, rechargeable fans, torches, and custom DC power projects.

• Verified 2000mAh Capacity: Guarantees solid runtime and steady power output for portable DC applications.

• Low Internal Impedance (≤45mΩ): Reduces voltage drops and minimizes thermal losses during active operation.

• Standard CC-CV Charging: Safe and reliable charging cycle with 0.2C constant current up to 4.2V peak voltage.

• Wide Device Compatibility: Excellent replacement cell for emergency security lights, backup power banks, and electronics.
