What's your battery's mAH (June 2009 Unibody only!)

Yeah it's fine. For the 17" it should be around 13000 mAH, but for some reason coconut battery reports the original as 1300(missing a 0 there). It's just an error, ignore it.
One of my 17 inch-ers reports 13269, however my newer one reports 12890 (hasn't been calibrated yet though).
Without calibration and only one use without power adapter yet.
Three days old, to replace a stolen MBP.

13" MBP, typical use is streaming Hulu or Netflix, surfing, email etc.. last nite I watched 2h 40m from Hulu, then surfed around reading forums and watching a few Youtube video's for 2h and change, battery showed 1:13 after that. I don't have 10+ applications open at once, don't see the need, since I'm working on one at a time, but usually when surfing have itunes running. When I'm watching Hulu, nothing but mail is open in the background. I've had this now for about a week and easily see 4 hours+ video playback/surfing/iTunes/email type usage.
Today I'm going on my 3rd hour of email's, browsing while listening to iTunes and batter shows now 2:25 to go. I have wifi on, BT off, screen brightness at 60%. Run the math all you want, fact is I'm getting well over 4 hours a session and not making any sacrifices to what I want to do with it.
On the math topic.. here is from my system profile
Charge Information:
Charge remaining (mAh): 2167
Fully charged: No
Charging: No
Full charge capacity (mAh): 5450
Health Information:
Cycle count: 4
Condition: Good
Battery Installed: Yes
Amperage (mA): -1092
Voltage (mV): 11169
Clearly it's pulling -1092 Ma, take the total... 5450 divided by usage 1092 = 4.99 hours, that's how the 13" MBP is getting 4+ hours easy.

bought my system about 3 weeks ago, I just did that battery test, and I think I did it wrong, I let the battery die out until it went into sleep mode, the problem is the system was completely shut down and I just started charging. Now my battery at fully charge only says 96%, what the hell it that about.
Some of you say keep it in that dead sleep state for 3 hours before charging, thats what I forgot to do, now what should I do? Should I let it die again and try this all over again?

I think I need to take mine back. I have the 15" and its a week old now. On the second day though it dropped to 6300/6500 and now its 6288. I'mm gonna do a full charge and drain and see what happens then. Otherwise I want to take it back for a battery replacement (I'd rather them not replace the whole laptop). I'm at 96% now after a week...
ok in another week im down another 200mAH. I'm now at 6100/6500 or 93%. This is nuts. My two week exchange period is expired this weekend, but I am not even in town to take it in. Should I call, or go in next week and explain. I'd like them to just replace the battery, not the whole laptop. Unless there is a chance something is wrong with the charging circuit. What do you guys think? I have tried a full drain and charge twice, waiting the 5 hours like I'm supposed to.
13" MBP / 2.26GHz default config.
98% health after 7 cycles (5386 mAh)
I haven't done a battery calibration yet but I should probably do it soon!

Call me not entirely convinced its going to achieve the
Presuming its linear (which it likely isn't, but we have no evidence any which way at the moment). After 1000 cycles it looks like I would be down to max of 50% charge.

Good enough for me. Don't think I'm at 99% health than I was when I was new ^^
