Pop a fully charged GoPro Rechargeable Battery into your HERO5 Black or HERO6 Black and capture your adventures. This rechargeable battery is based on a lithium-ion chemistry and has a capacity of 1220 mAh, slightly larger than the previous generation battery. Despite the size improvement, charge times have improved as well with this generation by taking advantage of the USB-C rapid charging feature. Additionally, an integrated authentication chip handshakes with compatible cameras communicating exact battery percentage, so you know when it's time to recharge.
