Macbook shutting down with new battery with 15 minutes remaining (consistent)

Question

Just installed a supposed new battery for the White Macbook 4,1 model, from an Amazon seller.  The battery looks authentic, fits well, accepts and fully charges, but it is a little more yellow in color than the rest of the casing.  That's all I can find wrong with it.
The problem I am having is that the macbook will shutdown consistently with ~15 minutes left on the charge (under 10%).  I get no low battery warning.  I have tried numerous SMC and PRAM resets with no luck.  Battery temperature and computer temperature appear to be fine so the unit is not overheating.  The only indication I can assume is suspicious is that the battery will draw over 2 amps at times as that magic time remaining approaches.  Battery cycle count is 3 and remaining capacity is over 5300 mAh.
Here is the pertinent info from System Profiler:

I'm running Lion 10.7.2 with 4 gigs of RAM installed.  I've read the Firmware version of this battery (110) needs updating but I can't find an updater that will run in Lion.  I also don't understand what ASMB0?6 means in the device name (what's up with the ?).  Again, the battery appears to be a legit Apple product and brand new by the cycle count (3).
Can someone help me resolve this issue?

HI kostby,
I've been trying to calibrate the battery but can't do the 5-hour sleep procedure since the computer doesn't go to sleep.  Although I have noticed that the last time the shutdown occurred, the battery indicator light was one and blinking.  So the battery thinks it is drained but the computer does not (hence 15 minutes remaining and no low battery warning).  So I took the battery out of the computer last night with blinking indicator light and left it alone overnight.  I reinstalled the battery this morning and am charging it now.  Hopefully it calibrated.
If not, I am going to ask for a replacement from the Amazon.com seller, since I just bought it "new".
Thanks for your insights.
