Item Revisions changes the item from the original and as such can not and should not be used to describe the item in question when talking about an unmodified (barely modified) game that does not include the mod which this information comes from.
Wow, get agitated much? As it seems you're not able to let this go, let me remind you that the original questions was "what is the deal with the Ring of Energy?" and "does it really have limited charges?". IR, as you so astutely points out, is a mod, but Demi notes the changes he's done to an item compared to vanilla; hence the quote I posted answered both questions. At least that was my understanding.
If it turns out that I still was mistaken, then *GASP* someone was wrong on teh interwebs!!1!
