So which is correct
I agree a FULL refresh charge is needed every once in a while

I went to a Lithium battery manufacturer site and this is what they say:
"The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three year life expectancy for batteries that do not run through complete charge cycles."

The 15% signal set by Amazon in the Kindle Fire prevents a full discharge which could damage the battery if it happens too many times. Occasional full discharge can re-calibrate the battery meter. I've noticed all my devices do this on their own about once every couple of months. I never had to do that intentionally.
Lots of small cycles could end the battery life before its time.
Within 12 to 18 months Amazon will have a newer eReader on the market. At that time most of us will upgrade to the new eReader. Thus, in all probabilty, we will never see our Lithium battery die unless it is defective and dies within the first 6 months.
I don't own any Lithium battery devices older than 3 years. They have all been discarded.
Obsolescence will destroy our gadgets, not battery death.
