Everstart is the brand name that the Wal Mart Corporation uses on the sealed lead acid (SLA) 12 volt 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.

1. Inspect and find Date Code

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.

2. Find the Month using the first Letter

Determine the month in which the battery was manufactured by the letter in the code. The letter "A" is the code for January, the letter "B" is the code for February and so on with "L" being December.

3. Find the Year using the numbers

Determine the year in which the battery was manufactured by the number(s) that follow the letter. The number(s) indicates the year. For example, a "0" means the battery was manufactured in the year 2000, a "1" means it was made in 2001 and a "9" means it was made in 2009.

4. Decipher Everstart Battery Codes

Put the month and year of manufacture together, and you have deciphered the Everstart battery code. This is similar for everstart maxx.


Try to find car batteries that have a two year warranty so you don’t have to buy a whole new battery if you have automotive troubles or corrosion. A replacement warranty will give you a free replacement in the situation of a dead battery or old battery with no core charge. Just check your battery warranty with the serial number. This can be found on a sticker on the top of the battery. You can do battery testing to make sure its good and works well with the charging system. It should come with a battery charger to avoid jump start. You can get a Walmart Battery or an automotive battery off of amazon.


if you’re having car troubles and think its your battery, make sure its not any other auto parts like your alternator. If not, then check your battery cables and battery posts. Then the issue is battery charge.
