There is another number (group) but 78 is what is recommended and what I bought. Google "Optima" and search for the best price.

There's been a slew of threads lately about Optimas crapping out in 4-6 months. The other alternative that has been brought up is an Exide Orbital from Napa. It's also an spiral wound gel battery and costs about $20-30 less. Another positive for some is that the top is also black, so it won't distract from other things (LIKE THE ENGINE) under the hood. They make a 75 size, just like stock. I peeled off the stickers to give the top a clean look.
