So are they programmed to die at a certain cycle? if one had the ability to reset the cycle , would it come back to life?
No battery lasts forever and if your using an older laptop chances are its not lithium.
No, nothing is preset to die.

I seem to be seeing this more and more often these days...both on genuine/original batteries(Apple in my case on all the laptops I deal with) and aftermarket

Aside from the swelling, though, I've also seen some batteries spectacularly fall on their face in ways that I've never seen before recently. 6 months ago or so I was given a 2012 MacBook Air primarily because the battery was bad. A couple of different battery diagnositic tools showed me that it was at ~25% capacity(relative to new) with under 700 cycles. Apple rates their "non-replaceable" batteries to hold 80% of their design capacity after 1000 cycles-most I see do better than this, so finding one that's that bad is kind of a rarity in my experience. I haven't fixed that one since I don't really care to sink $100+ in it(I'm picky and only use either genuine Apple or NewerTech, and usually the latter, batteries in computers without user-replaceable batteries-NewerTech usually runs around $100 and Apple generally charges $130).
As a side note, as long as you have a battery that will hold at least a little bit of charge, and isn't swollen, I suggest leaving it in your computer. Most laptops-regardless of brand-made in the last ~15 years or better take a performance hit without a battery in place. The reasons for this is that the charger usually isn't sufficient to power the computer when you're really hitting the CPU hard, so they will draw from the battery(even if it's only a few seconds at a time) as needed. I've never done it, but I've seen people doing sustained heavy computing(either gaming or scientific computing) actually drain their battery with the computer plugged in. Most people won't do THAT, but computers do still tend to throttle their performance pretty shockingly with no battery installed so that they don't get into danger of needing the battery. In my experience, the performance hit is noticeable even in browsing, word processing, and other "light" tasks as it will effect the overall responsiveness of the computer.
