I'm sure its true, for one cell in perfect lab conditions. One of those conditions is that it pretty much never sits there in a hot garage or parking lot, fully charged. The other is the cell can cool itself while it discharges, all alone on that lab bench.
Put it in a pack with hundreds of other cells, and park it out there in the real world, and you aint gonna see 3000 cycles.
2-4 years is typical for most of us. Number of cycles may not mean a thing, but number of days out in real world weather does.
