Put the power in clear lighting. Compatible exclusively with the COAST HX5R, HX6R and HX7R Flashlights, the Z555 ZITHION™ 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.
