How are the new versions differentiated?
How do I know if I'm buying a new one with improved battery life?
Several different vendors have 512's for sale with an inspection date of December 20 2017, however there is no indication inside or outside the box of 250% increased battery life. They say they think these are the new ones because of different packaging, but aren't sure.
