My battery died last Christmas and since my Jetta's had the same Optima in it for 10 years now, I was going to get the same one for my .:R. I checked in with a number of people, including the local folks at Batteries Plus, and they ALL said Optima batteries aren't what they used to be. I believe the Batteries Plus guys also mentioned that they're now built in a different facility or something like that too.
Anyhow, to keep me in line with the Optima-type 'class' of batteries, they recommended me the Odyssey X2 (SLI47AGM). It's an Absorbed Glass Mat (AGM) - type battery, which is also resistant to vibration. It has an OEM fit, so you can use the existing battery cover, insulating pad, cables, and mount.
