I decided to make a Google Drive spreadsheet to track my battery life.
I numbered my batteries 1, 2, 3, 4. I put them on a spreadsheet. I track the flight time and mah required to recharge the battery, then have the spreadsheet calculate what my maximum flight time would have been for that flight.
For example, I finished a 7.5 minute flight, and battery 3 needed 1384 mah. My formula reads: ((MaxMAH*.8)/(mah/flight time)), which gives me 21.68 minutes.
After each flight, I can charge the batteries, plug in the mah and flight time, and see the max minutes of flight time I would have had (max minutes still saving battery power).
Battery 2 went on a 16 minute flight, and needed 3223 mah. That gives me 19.86 max minutes I could have had on that flight.
I could make additional notes, like how much extra cargo I was carrying, if I did stunt flying, etc. I'm trying to see how long the batteries last on challenging maneuvers, so I'm going up and down like an elevator, climbing fast to 100+ meters, then falling fast to a few feet off the ground repeatedly.
I made the spreadsheet public in case you want to check it out: https://docs.google.com/spreadsheet/ccc?key=0AuBYCq7XpKkLdHVJNDNkN1dCd0lUdXpXSjExOUF2a3c
