Battery

The majority of car batteries are created by 3 manufacturers Delphi, Exide and Johnson Controls Industries. Delphi makes some EverStart models sold in Walmart and ACDelco. Johnson Control Industries makes Duralast seen in Autozone stores, Diehard - sold in Sears, Kirkland - the Costco brand, Motorcraft - which Ford sells, some of the EverStarts, and Interstate. Exide makes Exide batteries, Champion, Napa and even a % of the EverStart batteries. A car battery is one of the few things that you will most likely have to replace if you own a car more than about 3 years. Most other parts and accessories will last longer, but the battery in a car needs replacing every 3 years or so. Eastpenn-Deka Sold by Carquest, Napa ect.

Buy a fresh battery—one manufactured less than six months earlier. Batteries are stamped with a date code, either on the battery's case or an attached label. The vital information is usually in the first two characters—a letter and a digit. Most codes start with the letter indicating the month: A for January, B for February, and so on. The digit denotes the year: 0 for 2000, say. For example, B3 stands for February 2003.
