I have a 2008 Gen 2 and a 2012 Prius V. Both have quickly gone through a factory battery, and I have replaced both with the Optima Yellowtop, which I am very happy with (as well as done so for several Prius owning friends). I can't seem to find any information on whether there is a model that will fit in the Prius C, though. Can anyone help with this?
Hi GuamKelly, Prius C uses the same aux. battery as the Gen 2 non-SKS. See my thread for the specs. of the OEM battery and you should be able to find the Optima equivalent. Vincent
