Some members have said they liked the DieHard Platinum Automotive battery. Thought I'd get one. I think the G37 takes a Group 35, it's like ~$220.00 regular price, Sears has it at ~$155.00 today, online, store pickup if you're looking for one. Here's a link:

$220 or even $155 is WAY too much for a Group 35 battery. Just my .02

$125 for an optima yellow top sounds better to me:

Optima YellowTop 12V AGM Car Battery for $125 after rebate + pickup at AAP - DS46B24R

it says for prius, but using the same code and rebate you should be able to apply it to the correct battery

The die hard platinum is a rebadged odyssey battery which one of the best commercial batteries avail. Much better battery than the optima red/yellow/blue tops.

It appears the sale was only a one day deal. :-( I hope a forum member or two saved some bucks.
