My AppleCare is about to expire with my battery at 81%. Is there a good way to get it to 79% so I can get a new battery?

AppleCare covers the replacement of a MacBook Pro battery if it drops below 80% capacity before 1000 cycles. I have until the end of the year and I'm at 81% and 300 cycles. It would be nice to get a new battery in exchange for the $379(?!!!) I spent for AppleCare. I'll get an extra year of warranty since I purchased it on my American Express, but I would like to get something out of what I paid for AppleCare+ rather than pay $200 for a new battery and harass my credit card company into reimbursing me. Any thoughts on what to do? Will Apple give me a new battery if I tell them I'm 1% away?
