Prius C $4627.25 repair estimate

Gen 2, Gen 3, and v have the battery under the right corner of the cargo floor, and use the same battery. S46B24R
The c has the battery under the rear seat and Gen 4 has it under the hood.
It looks like the c uses S34B20R

I'm still wondering about the ACDB24R - does anyone know if this will fit a 2012 C2, or not?
Thanks,
