These cells deliver robust, long-lasting power so your light performs reliably for extended use. Battery specifications: Battery Type: Ni-MH; Battery Voltage: 6.0V; Battery Capacity: 3.5AH; Battery Dimensions: 178 x 33 x 33mm (7.0" x 1.3" x 1.3"). Built for durability — Kastar applies a mix-protection additive to the cathode to reduce material degradation during charge and discharge, extending the battery life up to 1200 cycles. The batteries feature a low self-discharge design: an embedded seal structure expands the crystal lattice, creating extra space for hydrogen so the cells retain charge longer than typical alternatives. Environmentally friendly Ni-MH chemistry contains no Hg/Cd/Pb. For added safety the pack uses a DBCK steel shell to help protect against explosion from overpressure.
