Questions about IAM-T2 Calibration, Firmware Update, and Battery

I just got my IAM-T2 today. I want to know when I should use the “Automatic Calibration” feature and when to use the “Factory Reset CO2 Accuracy” feature. Or do I never need those options?

About the Firmware Update, it does nothing when tapped. I also saw the same issue with another user who posted a review on Youtube. Is this normal?

For the battery, both the website and the manual says it uses Lithium battery. Lithium batteries are not rechargeable. Might it just be a typo of what should have been rechargeable lithium-ion battery? ——— Also, will it alert when the battery is full or do I just look at the battery indicator? Like many devices, I probably received my IAM-T2 with approx 40% charge. The manual says charging time is 6 hours so I’m assuming that to charge full, it should take at least 3 hours. But I’ve only been charging for 30 minutes and the battery meter shows full bars. Thoughts?

Thanks for the help!
