Everstart is the brand name that the Wal Mart Corporation uses on the sealed lead acid (SLA) batteries that it sells for automobile, marine and other motorized vehicles. There are just three major automobile battery manufacturers in the United States, although each of these makers may label their batteries for different brands. When purchasing a battery, it is wise to make sure that you are buying a fresh battery, and not one that has been sitting on the store shelf for many months. These three major battery manufacturers use a date code that is stamped on the battery.

Step 1

Inspect the battery to locate the date code. It will be stamped on the battery case or on the label that is on the battery. Look for a code that begins with one of the letters of the alphabet (A through L) and is followed by a number.
