Ahhh...
Yes, lithium batteries go dead over time even new in the box. They go dead faster if they are stored with their voltage not close to 40% full charge (too much or too little will both accelerate aging). I learned that years ago by buying an expensive spare (for later) and when I needed it, it was "already dead". Be sure to buy new stock to replace it. A battery from a salvaged kindle may have little life left in it.
