Reliable, high-capacity spare cells from Kastar — five 7.2V 2600mAh Ni-MH batteries designed to deliver extended runtime and stable performance for compatible alarm and control units. Key specifications: - Battery Type: Ni-MH - Battery Voltage: 7.2V - Battery Capacity: 2600mAh - Battery Dimensions: 50.29 x 42.4 x 14.37mm (1.98" x 1.67" x 1.15") Durability and cycle life: Kastar adds a mix-protection additive to the cathode to reduce material degradation during charge and discharge. This reinforcement helps extend the usable life of the cells to up to 1200 cycles. Improved self-discharge characteristics: An embedded seal structure increases the crystal lattice space, creating more room for hydrogen and reducing self-discharge so these batteries retain charge longer than typical cells. Safety and environmental profile: The cells are Ni-MH eco-friendly units that do not contain Hg/Cd/Pb. A DBCK steel shell is used to help protect the battery against explosion caused by overpressure. These replacement batteries provide a straightforward swap for the listed compatible models, delivering dependable power and long service life.
