I just replaced my Everstart 24f Value battery after about 65k miles and 3 years this month worth of service. It was $50 3 years ago. They are about ten dollars higher now. I think for the money spent they are outstanding batteries. The CCA is 585 which is like 120 CCA lower than the OEM. But, living in Arkansas I dont deal with a lot of that cold stuff. I will say though, in the dead of winter it never had a problem starting.
