Powerful, high-capacity replacement cells from Kastar designed to give your camera longer runtime and reliable performance. Battery Specification: Battery Type: Ni-MH; Battery Voltage: 6.0V; Battery Capacity: 2100mAh. Package Includes: 4-Pack Battery. Safety features include a mix-protection additive applied to the cathode to protect electrode material during charging and discharging, helping to slow degradation and extend service life up to 1200 cycles. The batteries use an embedded seal structure that expands the space of the crystal lattice, creating extra room for hydrogen and reducing self-discharge so they retain power longer than many standard Ni-MH cells. Environmentally friendly Ni-MH chemistry — contains no Hg/Cd/Pb — and a DBCK steel shell that offers protection against explosion from overpressure.
