Angry/CT/Me/Law/Guy makes it sound like every battery they sell has a 10 year warranty, with free replacements for the first 4 years, and free roadside assistance.
But can we trust them to tell us the whole story? Of course not!
It's really easy to find Crappy Tire batteries that have much shorter warranties - just go to their site!
Here's one that's only 6 years, with only 2 years free replacement, no roadside:

So, if any consumers were thinking, "Gee, Crappy Tire has good warranties on their batteries", think again.
Maybe some are good, but certainly not all of them.
And there's still no reason to think any are 'the best' - just another unsubstantiated claim by the Angry/CT/Me/Law/Guy.
Besides, what good is a warranty, if they just refuse to honour it?
