Not sure if you are asking the right questions. Why did this happen? Did your battery discharge last winter? Was it on a battery tender? If it did discharge below a certain point, the lead can flake off the plates inside the battery reducing the battery's life. If severe enough (and I don't know if modern designs mitigate some of this) plates can short out and kill one cell - the battery is completely dead. Obviously this did not happen. Since we have had decent weather, have you been riding the bike with no problems?
Was your Unreliable Battery a dry charge type that you added acid to? Was it a flooded or an agm type? Was it a premium name brand battery? Was it a cheap battery of dubious origin? Was there a warranty? The latter are usually prorated, and you might get some money back toward a new one (haven't seen warranties on bike batteries, but maybe...).
Your choices will depend on how much you want to spend and what sorts of backup you have (roadside assistance) and your tolerance for dealing with problems at the side of the road.
I tend to go with a name brand (Yuasa), and have always had lead acid batteries in the past. Next time I will probably consider a Lithium Iron because of the weight and the fact that I tend not to ride in cold weather. Only fly in the ointment w/ Lithium is they require a special charger, so I'd have to buy yet another one.
