The exact battery capacity is not in the specs, or otherwise officially revealed. And that's the case generally for all Garmin devices. However at some past models, you can find testimonies from people who disassembled some of the devices. For example you can find several such posts about some Garmin models at http://www.f-blog.info/garmin-fenix-6x-pro-disassembly-or-teardown-whatever-you-say/ Guessing from similar posts available online, I'd tell the capacity of Instinct 2 will be roughly around 1-2 Wh too. The long times Instinct 2 can reach, are not really coming from an exceptionally big battery, but rather from optimized hardware and software.

Operational time what matters at the end of the day. I only wanted to calculate approx. current consumption based on the capacity/operation time. Just out of curiosity.
