Anyone have experience with Rayovac car batteries?

[TowX]

So the temps dropped into the low 20's yesterday and of course the X5 battery decided to crap out when it was time to come home from the inlaws after turkey dinner yesterday. Normally I'd just get an Interstate but my favorite local shop is closed until Monday so I went to my neighborhood Batteries Plus to get a Werker, and a new PC680 Odyssey for the race car.

No more Werker in a Group 49 size, but they now sell a Rayovac- 850 CCA and an RC of 180. 2 year replacement warranty, 84 month prorated. But I've never seen a Rayovac car battery before. $119 after a $10 coupon discount since this store just opened. But I didn't see a nipple for a vent on the battery so I opted out. Any input?
