Should I keep it in the fridge? Should I constantly discharge and recharge? Should I keep my hopes up or should I buy a new battery?

There is no hope for li-ion batteries in my experience, if they get old, they just get old, buy a new one, recycle the old one properly.
Li-ion batteries usually last a finite amount of time, regardless of use, though use will speed up the degradation process. Unfortunately it's just how it is. Read here for more on Li-ion batteries.

Agree. When you have noticeably reduced runtime, your battery pack has lost a cell. There's no coming back from that (other than tearing the pack open and replacing the cell, a procedure not recommended for non-techies). Aug 5, 2014 at 19:39
