I've bought for a friend and will ship it for him along with some other items. Unfortunately, as I went to post it turns out you can't post anything with a Lithium Ion battery via air (given I've had tons of devices imported, not to mention I use laptops etc on planes, I didn't realise this was even a thing). So he asked for me to leave the laptop and post the rest. On the postage box I received from Apple itself with the time capsule it had a battery warning sticker. Which made me think, does the time capsule have a battery too? I have tried searching and 1 Amazon listing does make mention of a battery, however nowhere else does. I've looked at pictures of a teardown and can't see a battery either: https://www.ifixit.com/Teardown/AirPort+Time+Capsule+A1470+(Mini!)+Teardown/15067 Anyone know for sure whether there is, or isn't, a lithium ion battery in the latest time capsules?
