Kastar 4-Pack 6V Ni-MH 4400mAh Replacement Battery for Streamlight 9032, SL20, SL20S, SL20X (W/AC, W/DC), SL20XP LED W Steamlight SL-20XP-LED

High-capacity 4-pack of Kastar Ni-MH replacement cells designed to extend runtime and deliver reliable power. Each rechargeable battery is 6V with a 4400mAh capacity and measures 178 x 32 x 32mm (7.0" x 1.25" x 1.25"). Durability and cycle life: Kastar adds a mix-protection additive to the cathode to protect the active material from degradation during charge and discharge, helping the cells last up to 1200 cycles. Low self-discharge design: An embedded seal structure enlarges the crystal lattice to create extra room for hydrogen, reducing self-discharge so these batteries retain charge longer than many alternatives. Environmentally conscious construction: The Ni-MH chemistry contains no Hg/Cd/Pb and is more eco-friendly than older chemistries. A DBCK steel shell surrounds each cell to provide protection against overpressure and reduce the risk of explosion.
