The problem is here:
                   Store ("Bat 8Cell", Index (Arg1, 0x09))
                   Store ("236", Index (Arg1, 0x0A))
                   Store ("Lion", Index (Arg1, 0x0B))
                   Store ("Acer", Index (Arg1, 0x0C))

If you look at the value being dereferenced as the destination arg, it's 
a string.  So this should really store a string to a string.  For some 
reason, ACPI-CA is attempting to convert the string to an Integer before 
storing it.

                         Name (BT0I, Package (0x0D)
                         {
                             0x01,
                             0x19C8,
                             0x19C8,
                             0x01,
                             0x39D0,
                             0x014A,
                             0xDC,
                             0x012C,
                             0x0294,
                             "ANA",
                             "110",
                             "Lion",
                             0x00
                         })

Looking more carefully, it looks like commenting out just the last line 
("Acer") would suffice.  Index 0xC is actually an integer (0x00) so this 
is what triggers the Integer conversion.  I'm not sure how the 
conversion rules should be modified to take this into account.
