High-capacity replacement batteries engineered for extended camera use. These Kastar Ni-MH cells deliver 6.0V at 2100mAh to keep compatible Pentax models running longer between charges. Battery Specification: Battery Type: Ni-MH; Battery Voltage: 6.0V; Battery Capacity: 2100mAh. Package Includes: 4-Pack Battery. Durability and cycle life are improved by Kastar's cathode formulation: a mix-protection additive is incorporated into the cathode to slow material degradation during charge/discharge cycles, helping the cells reach up to 1200 cycles. For reduced self-discharge, an embedded seal structure increases the crystal lattice space, providing more room for hydrogen and allowing the batteries to retain charge longer than standard cells. These batteries use environmentally conscious Ni-MH chemistry and do not contain Hg/Cd/Pb. A DBCK steel shell is used to reinforce the cell and help protect against explosion caused by overpressure. Compatible with the following Pentax models: R-100 R-200 R-300 R-100X R-115 R-115N R-125 R-125N R-127 R-135 R-135N R-122 R-122N R-123 R-123N R-200DN R-200X R-202N R-202NE R-225N R-2422NM R-315 R-315N.
