My Optima red top just kicked the bucket after 5+ years of 1-2x a week use. I didn't buy another one as I couldn't justify the cost vs no real upgrade in performance (it was lighter than stock, yet the same weight as my new battery).

I found this interesting:
"The majority of car batteries are created by 3 manufacturers - Delphi, Exide and Johnson Controls Industries. Delphi makes some EverStart models sold in Walmart and ACDelco. Johnson Control Industries makes Duralast seen in Autozone stores, Diehard - sold in Sears, Kirkland - the Costco brand, Motorcraft - which Ford sells, some of the EverStarts, and Interstate. Exide makes Exide batteries, Champion, Napa and even a % of the EverStart batteries."
