I will second that.. Have had it happen in fact.
True story much longer condensed
OEM battery died (under warranty)
Opted for a better battery (Lifetitime warranty $60.00)
1 week later: Got new LIfetime battery (Warranted $0.00)
Many years later.. Started car, drove to dry cleaners,,, Picked up Uniform.. Car would not start, had to call AAA for a Jump
It went from GOOD to TOAST in less than 1/2 mile!!!!!
New battery (5 year warranty but grandfathered) would have cost 150.00 had I had to pay for it.. but $0.00... Best 60 bucks I ever spent!!!!
That battery... Outlasted the car.
