How To Tell How Old Your Battery Is

Knowing the age of a battery can help you to determine its condition and whether it needs replacement. Though some batteries have expiration dates printed on them, others do not. Fortunately, there are a few ways to tell how old your battery is.

Here are the steps you can take to find out the age of your battery:

• Check the expiration date if printed. Some batteries will have their expiration date printed on the battery itself. If this is the case, the expiration date will tell you how old the battery is. An expiration date will be written as a month and year, such as “EXP 05/2021” or “EXP May 2021”.
• Look at the manufacturing code. If a battery does not have an expiration date printed on it, you can find out the age of the battery by looking at the manufacturing code. The manufacturing code will also be printed on the battery. The code will be four numbers, such as “3413” or “1432”. The first two digits of the code indicate the year in which the battery was manufactured. The last two digits indicate the week of the year in which the battery was manufactured. For example, if the code reads “4321”, this means the battery was manufactured in the 42nd week of the year 2043.
• Check the battery's condition. Even if you cannot tell exactly how old the battery is, you can usually tell if it is relatively new or old by looking at its condition. If the battery looks worn or corroded, it is likely that it is old and may need to be replaced. On the other hand, if the battery looks new or has very little wear, it is likely that it is relatively new.

Knowing the age of a battery can help you to determine its condition and decide whether or not it needs to be replaced. If the battery has an expiration date printed on it, you can use this to find out how old it is. If not, you can look at the manufacturing code to determine the age of the battery. Additionally, you can use the condition of the battery to get an idea of how old it is.
