Here's the deal. Apparently, it seems that Apple's battery creation has some weird anomalies that is.. well.. just weird. Here's how you do this: - Goto The "Apple" in the Top Left Corner, select "About This Mac" - Select "More Info..." - Goto "Power" on the side - Copy all info from "Battery Information" (Don't need System Power Settings) So far, I have: Battery Information: Model Information: Serial Number: DP-bq20z951-3a35-7112 Manufacturer: DP Device name: bq20z951 Pack Lot Code: 0000 PCB Lot Code: 0000 Firmware Version: 0042 Hardware Revision: 0001 Cell Revision: 0119 Charge Information: Charge remaining (mAh): 12489 Fully charged: Yes Charging: No Full charge capacity (mAh): 12518 Health Information: Cycle count: 26 Condition: Good Battery Installed: Yes Amperage (mA): -3048 Voltage (mV): 8188 or, 12518 mAh as 100% charged. It seems that one of the users here have over 17000 mAh, which is awkward because iFixit stated their test system only had 12xxx mAh also. I want to see how many people have the 12xxx mAh or if there's anyone else who is lucky, have over 17xxx mAh as their max capacity. Please also state if you have calibrated your battery or not.
