Battery Capacity: 500mAh;
Battery Dimensions: 2.3" x 0.81" x 0.42" ( 58.24 x 20.59 x 10.63 mm).
Safety Assurance: A mix-protection additive is added to the cathode, shielding the material from degradation during charge and discharge, and extending service life up to 1200 cycles.
Low Self-Discharge: The embedded seal structure expands the crystal lattice space, creating more room for hydrogen, so the batteries retain power longer than others.
Environmental Protection: Ni-MH eco-friendly cell, free of Hg/Cd/Pb, causes no pollution to the environment, and uses a DBCK steel shell that guards the battery against explosion due to overpressure
