So my battery died yesterday and I'm looking at this as an opportunity to upgrade. I heard great things about the optima red top but I'm not sure which one I'm supposed to get. At their website, its says:

Part Number: RED35
CCA: 720
Model Name: Optima
Battery Group Size: 35O


Part Number: RED75/35
CCA: 720
Model Name: Optima
Battery Group Size: 75DTO

Whats the diff? And anyone know the pricings? Thanks.

 

jeez man just get one at advance

 

I picked up the 75/35 at AutoZone for $99 but....I work there :-)
