Can you help us locate and read battery codes? Yung manufacturing date sana. Salamat in advance. I bought an AC Delco S54459 car battery.
Locate the dot matrix stamp on your car battery. There should be one. It's an alphanumeric code. I bought the same battery last year.

Here's how to decode your AC Delco battery's date stamp.

Ex. KH5I24 - The third character (number) refers to the year of manufacture, 5 is 2015. 4th character (letter) corresponds to the month, I is September. The last 2 characters (numbers) corresponds to the day. In this example, KH5I24 was manufactured in September 24, 2015.

I am not entirely sure what the first two letters stand for. Best guess is the factory code where the battery was manufactured.

Hth. Cheers!
