My MacBook Air7,2 has a claimed battery cycle count of 1000.
It has a current cycle count of 114.
My question is, will I halt the cycle count while ever I use the Mac on mains power?
In other words, does the Mac draw power from the battery when it's connected to mains power?
And If perchance it doesn't, will having the Mac on mains power all day harm the (lithium ion) battery?

Apple does not claim or guarantee that a battery will last 1000 cycles. Apple says that the battery is DESIGNED to last up to 1000 cycles.
The more you use the battery with the charger, the less cycles will be accumulated. That said, do not do that 100% of the time. At least once per month use it under battery power so the battery gets some 'exercise'. Lithium batteries other wise will deteriorate at a faster pace.
There are rare instances when the Mac is being pressed for electrical resources where the battery may be tapped for additional energy when being powered by the charger.
Ciao.

Oh, okay the plot thickens.
In five years time, I should have enough spirit of adventure to remove the back of my Air and replace the battery.
Either that or I'll be considering upgrading to the latest manifestation of MacBook.

My rule of thumb is, regardless of the number of cycles, replace the battery prior to 5 years of use. Old lithium ion batteries can expand and damage the Mac.

Thanks Ciao
I take your point about 'Designed', and the further info has given me confidence that I can extend the battery's longevity, which is what I was hoping for.
