Johnson Controls makes the batteries for a good number of different brands, shown here:

For my Golf TDI, there were matches for these brands: Everstart, Blaine Farm and Fleet, DieHard, Kirkland Signature, Optima, and Duralast.
The DieHard battery had less than 600 CCA.
The Optima Red Top, size 35, had 720 CCA. It may also be sold under the Blains Farm and Fleet brand same part number (RED35).
The Duralast Gold, size 94R, had 650 CCA and is sold at Autozone.
Sam's Club sells the Energizer (aka Kirkland Signature), size 94R, with 765 CCA.
The Everstart battery, size 94R, 910 cranking amps, 765 CCA, sold at Walmart. That's the one I bought. It had a three-year replacement warranty, nine year pro-rated warranty, and only cost $75!
Before going to Walmart, I took at look at what O'Reillys had to offer. They had Optima Red Tops, but I didn't feel like paying $150+. And something else but they would have had to order it. Walmart had several batteries in the correct size, ready to go.
