I think my battery is original from '93. The year sticker on the top of the battery has the 3 punched out, so I am guessing that means 1993. It is an Interstate battery, and it looks old. But, the engine starts instantly upon turning the key, and it only has to crank a second or two when it is really cold, ie 5-10 degrees. If I am misreading the sticker, please let me know as I have been wondering how long it has to live before replacement, especially since the truck only has the one battery.
