Almost certainly the eleven-umpteenth case of what I now call "Battery fatigue"........Batteries in Vipers (IN MY OPINION) should be changed routinely every 2 years ! It is not worth the grief to extend the battery use. (I do not sell street batteries...lighweight racing only!)
Not enough Amp-Hour capacity left in your battery. A DRB could have told you 'why' the first time, except you erased the codes when you disconnected it. {I would have, too!)
Buy a new battery! See if the new center-post gel Excide is available.....or modify your battery tray (be careful, it has a temperature sensor!) to accept a slightly-too-tall Optima.
Or consider a very lightweigt Oddessey racing battery
