The 2NPP/B Battery from Antique Auto Battery in Hudson, Oh is a repop of the Ford Battery that came in a 57 Ford. I've had mine for about three weeks now and I can report it seems to work very well, even after the starter gets hot. This battery has the Odessy dry cell inside and claims 650 CCA. I've had no reason to check the advertised 650 CCA because it works so well.
The wet cell battery is a joke played on unsuspecting people and has only 285 CCA when advertised as 550. It would not start my car once the starter got hot.
