So my X2 died again today. (It stopped working last week, then suddenly started working again, only to die again today...) And I was on here reading and I was curious because it seems the answer is whatever the poster at the moment thinks. What is the lifetime of these batteries? Seems kind of crazy to spend 40 dollars on a battery only for it to last such a short time. (From what I am reading most people only get a few months of life out of these style batteries.) So I was wondering does anyone know what the average life span of the X2/Twist 1300mah variants?
