    Conversion Equipment Lead Acid Battery Date View

    Batteries have a shelf life and will eventually die even if they're not used. To check the date on a battery, you need to know what the characters on the battery mean. The first character will be a number from zero through nine. The date on top of a battery corresponds to the year and month of manufacture. The number corresponds to the year and the letter corresponds to the month. So, if you see an 8D on your battery, it means that it was manufactured in April. “””The first number is the month and the letter is the year. For example, if the code is 3L, the battery was made in March of 2013. If the code is 11J, the battery was made in November of.
