Ok, only two batteries are known to BIOS, one is NiMH, the other is Li-Ion.
Li-Ion has hard-coded design capacity of 0x1770 or 6000.
So, this is bug in BIOS of your machine, you might call technical 
support if you care.
I am not aware of any actual use of design values, so you are pretty 
safe while ignoring them.
                If (^^PCI0.LPCB.EC0.MBNH)
                {
                    Store (0x2328, Index (PBIF, One))
                    Store (0x1C20, Index (PBIF, 0x04))
                    Store ("OANI$", Index (PBIF, 0x09))
                    Store ("NiMH", Index (PBIF, 0x0B))
                }
                Else
                {
                    Store (0x1770, Index (PBIF, One))
                            ^^^^^^
                    Store (0x39D0, Index (PBIF, 0x04))
                    Sleep (0x32)
                    Store ("LION", Index (PBIF, 0x0B))
                }
