Put the power in clear lighting. Compatible exclusively with the COAST HX5R, HX6R and HX7R Flashlights, the Z555 ZITHION(TM) rechargeable lithium ion battery recharges by quick connection to the integrated USB-C charging port located directly onto the flashlight-creating a no-hassle, lightweight power solution. Overcharge/discharge protection circuits make powering up as simple and safe as possible. The battery is backed by COAST's one-year warranty against defects in materials and workmanship.
