My apologies, Bob. I shouldn't have taken offense at your reply, and I do appreciate your efforts to help me. It may have been my fault in not being clear with my question. I will try to be clearer.
The battery is labeled 10400 mAh and 11.1 V. I know the formula for mWh, and I expect that it will report a maximum capacity of 115440 mWh. Battery Bar Pro should show this as "Battery Wear: [X]% of [Maximum Capacity] mWh.
After calibration, Battery Bar Pro is showing the following: Battery Wear: "2.6% of 96,780 mWh"
96,780 is EXACTLY 11.1 * 8800. EXACTLY.
There are two possibilities - either the seller sold me an 8800 mAh battery, mislabeled as a 10400 mAh battery - or the seller is correct in telling me that the problem is with my computer. The seller is claiming that because of a limitation in its BIOS, my computer will not detect, or will not report, a 10400 mAh battery correctly. I have never heard of such a limitation, but I was hoping that someone on this forum might know more about this issue.
I have an Acer Aspire 5740-5513. I am running Windows 7 64-bit and BIOS V1.28 from Phoenix Technologies.
The original battery was a 4400 mAh battery.
I do not need to know whether my battery is dying, or cold, or how to convert Amp Hours to Watt Hours, or whether a battery really gets its full rated life. I need to know whether I have been defrauded.
