I was at Costco the other day checking out a replacement battery for my 2006 MR. I was looking for a replacement for the stock group 35 battery that was lighter. They did not have any group 26 batteries but they do have the Honda group 51 battery.

I noticed the ratings are lower for this battery. For normal type driving you think it would make a difference? Is the Honda group 51 battery a viable option? Opinions? thanks
