Just bought an Optima DS46B24R YellowTop direct replacement battery for my 07 Prius. I will be paying less than $125 after tax, shipping, cash back, coupon code, and main-in-rebate. I'll post information on where I bought it from after I receive the battery. Check back in a few days. Here is the $25 rebate link Optima Battery Rebate
Don't think anyone with a V will need a 12v auxiliary battery anytime soon but here is the link to the 04-09 Prius forum where I will continue this post. http://priuschat.com/forums/gen-ii-...46b24r-yellowtop-under-125-a.html#post1515799
