I ended up with a Yellow Top from Mopac. Despite recent criticisms regarding Optima's quality control, I felt that it was worth it for a couple reasons
1. Sourcing the battery was a large factor. If I had more time I'd probably try to find the Deka Intimidator cheaper or research other options. Orbitals at Canadian tire were comparable to red top Optimas not the yellows, and the marine version albeit extremely stout is not meant for winching, its designed for slower continuous draw.
2. Most bad Optima batteries fail in about a year or sooner, Most Exide orbitals fail out the warranty period (at least pro rated). (Optima warranty is 3 years full replacement)
3. I didn't go pricier because I felt it was unnecessary for my application, If my Optima is decent it should give me years of service at a level of performance that satisfies me. I paid 251 for the yellow out the door
To the above post, I figured as much. They basically give you a discount (pro rated warranty) on your next battery purchase so you keep buying batteries from them. Its important to remember big chain stores don't offer these "great" warranties to lose money.
