acpi -i crazy batter capacity on VAIO SVS13A

Hello all,

This is not really a issue as the battery percent and all other things related to sleep, suspend ans so on are working correctly.
if i run a cpi -i in a row i get different output every time:

[j0lly@0x0000][~]
08:16:30 $ acpi -i
Battery 0: Discharging, 67%, 02:40:27 remaining
Battery 0: design capacity 4708 mAh, last full capacity 4708 mAh = 100%

[j0lly@0x0000][~]
08:16:32 $ acpi -i
Battery 0: Discharging, 67%, 02:41:00 remaining
Battery 0: design capacity 4712 mAh, last full capacity 4712 mAh = 100%

[j0lly@0x0000][~]
08:16:33 $ acpi -i
Battery 0: Discharging, 67%, 02:41:00 remaining
Battery 0: design capacity 4712 mAh, last full capacity 4712 mAh = 100%

[j0lly@0x0000][~]
08:16:37 $ acpi -i

Battery 0: Discharging, 67%, 02:40:52 remaining
Battery 0: design capacity 4713 mAh, last full capacity 4713 mAh = 100%

[j0lly@0x0000][~]
