I've got the same laptop with one battery, but I'm using ACPI. None of the current user-space utilities parse this stuff particularly well (the filenames in /proc/acpi have changed), but the data all look reasonable.
#cat /proc/acpi/battery/BAT1/* alarm: 3000 mWh present: yes design capacity: 57420 mWh last full capacity: 57420 mWh battery technology: rechargeable design voltage: 14800 mV design capacity warning: 3000 mWh design capacity low: 1000 mWh capacity granularity 1: 200 mWh capacity granularity 2: 200 mWh model number: LIP8084DLP serial number: 40086 battery type: LION OEM info: Sony Corp. present: yes capacity state: ok charging state: charging present rate: unknown remaining capacity: 56670 mWh present voltage: 16746 mV
