Duracell GoPro Hero 4 accu double pack

It Works but doesnt last as long as my previous battery. This new one last only an hour. Thats half as long as my other one. But it is jus a spare so...

I love how fast it charges but I don't like how it sometimes loses battery life while the camera hasn't even been turned on. Overall, good battery. I have only had two incidents where it died on me during a shoot.

I am very please of the result on buying this product from B&H.the help i recieved from customer service and technician need to be commended.Good job people very satisfied.

Great price for the real thing, not a cheap lookey likey one.

I only buy GoPro when it comes to batteries. It charges fast and does what its made to do.
