does anyone in houston know of a local shop where i can find a good replacement battery? factory one keeps dying...have read up on it in some threads in the forum, apparently the factory battery doesn't have great capacity. thanks for any info.

Go get a Sears Diehard Platinum. I have one in my Infiniti. It's the best battery I've bought as a replacement.

Also, get a Battery Tender. It'll keep your battery charged. I use one on both the GT-R & Infiniti. I've never had a dead battery.

Just had mine replaced under warranty; it had a bad cell.
