no, 1000 cycles doesn't mean 1000 charging events will end it. 1000 cycles from 100 to 0% will end it, and if its like current batteries, you get more than say, 10X as many cycles when you only use 10% of the battery per cycle

In addition to what you said, after the rated cycles most Lithium batteries still work and can still hold 70~80% of their original capacity.

Once charging/discharge times come down, trickery can be used to turn 1000 into 10,000 cycles easily. If you can charge fast, you can isolate cells alto charge/discharge them individually, only jumping to other cells once the first is full. Essentially, it's wear leveling of batteries as done with flash memory. At the moment individual cells cannot charge/discharge fast enough to fully enable this.
