The Optima Yellow Top for the Prius is a 38Amp-hr battery! The battery may be slightly bigger size wise, but that does NOT mean it has a larger capacity, as is the case here. Optima’s use of spiral cells is the reason why lower capacity, b/c the spirals waste sapce, unlike a traditonal plate design (no wasted space). Bigger IS NOT always better.
