Battery Specification: - 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 x14.37 mm) Long Runtime: High-capacity Ni-MH construction supplies stronger, longer-lasting power so your cordless handset performs reliably between charges. Durability & Cycle Life: A mix-protection additive is incorporated into the cathode to reduce material degradation during charging and discharging, extending service life to up to 1200 cycles. Low Self-Discharge: An embedded sealed structure increases crystal lattice spacing to accommodate more hydrogen, which reduces self-discharge and helps the batteries retain charge longer than standard cells. Eco & Safety Features: Environmentally friendly Ni-MH chemistry contains no Hg/Cd/Pb. A DBCK steel shell surrounds each cell to help prevent rupture or explosion from overpressure.
