Holy old thread! Hey my Orbitals are still going, so to speak. I killed one of them running my seat heaters all day more than a few times, it wouldn't hold a good charge anymore even removing it and trickle charging overnight. But Checker gave me a deal on the replacement, I think they prorate the cost over the 80 months or something, anyway it was about half price for a brand new one. So I've got one newish (6 months?) battery, and one 3 year old battery, both doing well.
I'm still happy with the decision and would recommend it- buy a super common battery from a chain store that comes with a warranty, so you can get a new one just about any time, any where. Not the place to be "exclusive," IMO.
edit: And in my first and only yellow top experience, Crash that battery I bought from you is still doing well. It spent a brief tenure in the plow truck, then moved over to to Subaru, then it went camping on the Ouray trip in the camper, then it rested inside the garage for a few months. When it started getting cold I brought it inside the house and stuck it in the closet. And wouldn't you know it, two weeks ago someone
left something on and ran the battery down in the Subaru, so I swapped in the yellow top and voila back in business. After trickle charging and testing the other battery it's back in there now, with the Optima back on the shelf ready for its next job.. one thing I learned last winter being an hour away and 10° colder than everyone else is having a nice warm backup battery inside the house can be a wonderful thing, glad I got one of the good ones!
