Extend the run-time of your GoPro HERO4, HERO3+, or HERO3 by up to five times with the black ALL DAY 2.0 5000mAh extended battery from Brunton . The battery is designed to integrate with the GoPro Standard Housing, serving as its own backdoor for a water-tight seal. Like the Standard Housing, the battery is waterproof to depths of 131' feet, making it ready for any adventure. Additionally, the battery can be used to charge your phone or select tablets using the 5V, 2.1A USB output concealed behind a water-tight side access door. Behind this door you'll also find the micro-USB input for charging the device. A 2-in-1 charging cable is included which features Apple Lightning and micro-USB connectors on one end and a full-sized USB connector on the other.

Note: The battery attaches to the back of the GoPro Standard Housing, not the Dive Housing (or the original HERO3 housing).
