I have used a bunch of the #41-4 batteries from Walmart. My lil cousin tortures his and this is after it got us home from picking up the car 2 hrs without an alt belt. We stopped at a Walmart on the way and picked up a spare in case the 1st died. Drove with 1 headlight for the last 1/2 hour and still made it home on the 1st one. Otherwise it's a steal, Euro car batteries are usually $100. Funny thing is the computer at Walmart does not offer MANY of the cars the thing fits, but I knew how to cross-reference it in my head. Consumer Reports put Advance Auto at #1 quality and Walmart in the middle, Die Hard was a bit lower.
