How to tell how old an electric golf cart interstate battery is?

To determine the age of an Interstate battery in an electric golf cart, you can look for a stamp or label on the battery itself. Interstate batteries typically have a date code that indicates the month and year of manufacture. The date code is typically a combination of letters and numbers, with the letter indicating the month (A for January, B for February, etc.) and the number indicating the last digit of the year (8 for 2018, 9 for 2019, etc.). For example, if the date code on the battery is C7, it means the battery was manufactured in March 2017. If you are unable to find a date code on the battery, you can contact Interstate Batteries directly for assistance.
