I guess your not getting it.
The point folks have tried to get across to you is, When one buys a quality battery, such as a Odyssey, northstar or even Deka AGM, you dont need a warranty.
I'm afraid you're the one who's not, "getting it". None of what you said changes or answers anything I brought up. I'm not arguing that these "super batteries" lack quality. I get it, they're wonderful.
But the fact is your battery is going to fail.... PERIOD. I don't care if it was made by Canadians, Quakers in Pennsylvania, or Chinese Communists in Beijing. And it doesn't matter what the warranty is or isn't. Or how wonderful and powerful you think it is.
No one is doubting the fact your "super duper battery" may last a bit longer than most. And that's all well and good.
But eventually it will fail. It won't last forever.
And when it does, it will more than likely do so unpredictably and unexpectedly. Then what? After you find there isn't a store within 100 miles that carries that brand you want it replaced with, because it was such a fantastic battery. But now that doesn't mean crap, because it's dead.
Your car, and you, aren't going anywhere until you replace it. And that should be a fast and effortless process. It's not if you have to order the thing and wait days for it.
All I'm asking, is to show me a way I can get it replaced as quickly and effortlessly, as I can with ANY of the other batteries from the major auto parts suppliers, and I'll buy one in a heartbeat. You don't seem to want to understand convenience is the key here..... Not having the most powerful battery in a 20 sq. mile radius.
I would rather have to replace a battery a bit more often, than I would having to screw around taking the bus, while waiting days to have one delivered. Not to mention then having to do the installation myself, along with hauling the old core back. Which by the way, I don't mind doing at all. But there are many people, women included, who can't, or don't want to mess with that.
The point is when you need a battery, you need one immediately. Not in 2 days. And not next week.
This is the part you're not getting. Or else don't want to. Rapid replacement is key to automotive battery failure. Because most people don't have the time to screw around ordering batteries, and waiting days for them to be delivered.
Because their car is sitting dead, and they sit unable to go to work, the grocery store, or anywhere else. Again, this is that part that has to be addressed. Not how wonderful they are.
Batteries aren't tires and brakes, that you can gauge wear on, and replace at your convenience, when you have the time to deal with it.... You want the old one out, and a new one in as quickly and effortlessly as possible. So you can be on your way. This eclipses having some "super battery", that most people don't even require.
