In Justice League: The Animated Series' Season 2 Episode 5-6 (Only a Dream), when Doctor Destiny is taking down all the Justice League members, only Batman and The Manhunter were able to escape his nightmare longer than anyone could.
In this two-part story, Batman goes (for what I could imagine) to go without sleeping at all for ~ 2 days. I remember reading somewhere that Batman could go up to 80 hours without sleeping (although he is known to take micro-naps/sleeps in between).
So in the comics, has Batman ever demonstrated this feat? If yes, how long has he gone without sleeping?
PS: Looking for answers where Batman goes completely sleepless, not the times where he takes short/micro-naps.
