Get Most Years out of Battery?

Question

From Apple web site and posts here I know:
1. Battery should be discharged and fully charged once a month.
2. Doesn't matter whether you use 10% or 70% of the battery before you re-
charge it.
3. To make it last the longest, you should use it often.
My question: It says the battery should last 300 full charge and discharge cycles.
If that's the case, will my battery last longest if I only use 10% of the battery each day, and keep it plugged in the rest of the time? 10% per day x 30 days would be 300% or 3 full recharge cycles per month. That would be 36 full recharge cycles per year. 300 full recharge cycles would be a little over 8 years.
Is that a good way to go, or is 8years not likely?
Or would I get just as many years out of the battery by using up 50, 60 or 70% of the battery each day?
Thanks

Answer 1

1) Yes but no more than that.
2) No it doesn't.
3) Yes. Like us, batteries need exercise and the more exercise you give it the longer it's be able to maintain charge. You should look to have around 200-300 cycles on the clock by about the 2 year stage.
