Cosmos uses AA batteries in its controllers. A figure that has been previously reported is incorrect, and unfortunately, widely circulated. We’ve seen a wide range of performance and expect four to eight hours depending on light, environments, type of content, and other variables. The quality of the battery itself may also impact longevity. Our engineering team will continually work to optimize for performance. We’ve tested NiMH rechargeable batteries and found them to perform well.
