The re-chargeable battery is not replaceable. The current battery life span is approx. 5 years (it will still charge at that point but will gradually retain less and less power). Like a laptop, it will still be functional plugged in. We are in the process of sourcing a battery with longer life span and will provide an update once we confirm with our supplier.
The LED has an estimated life of 50,000 hours, which is approx. 6 years if left constantly on (12 years if you use it 12 hours/day). The LED won't die when it reaches 50,000 hours but will gradually get dimmer.
The built-in magnets in the cover are designed to be strong so Lumio can stay in place when you attach it a metal surface. It may impact certain magnetic media such as credit cards or other electronics if it's placed in close proximity. Your Lumio will come with a slim magnetic cover that you can easily attach to shield the magnetic force from harming other electronic devices. You can carry Lumio safely in your bag with other electronic devices. I will share detailed photos of the magnet cover on our 3rd project update. Feel free to send us a message if you have any concerns or additional questions.
