Built to deliver stronger, longer-lasting power so your cordless base performs reliably between charges. Key Specifications: - Battery Type: Ni-MH - Battery Voltage: 7.2V - Battery Capacity: 1000mAh - Battery Dimensions: 1.98" x 3.34" x 0.57" (50.29 x 84.8 x 14.37 mm) Durability & Safety: Kastar incorporates a mix-protection additive into the cathode to help prevent material degradation during charge and discharge cycles, extending usable life up to 1200 cycles. The cells are enclosed in a DBCK steel shell to help guard against explosion from overpressure. Low Self-Discharge: An embedded seal structure enlarges the crystal lattice space, creating more room for hydrogen and reducing self-discharge so these batteries retain charge longer than standard cells. Environmentally Friendly: These Ni-MH cells do not contain Hg/Cd/Pb, minimizing environmental pollution while providing a safer replacement for your Panasonic cordless station unit.
