I bought a interstate deep cycle 24 battery from gander mountain in september of 2012. I used it twice in my camper on hunting trips. Battery wont hold charge and leaks acid from the top. I brought the battery back to gander mountain in forest lake, mn. The battery has the dates on the battery on the day purchased, a gander sticker on the battery and a card on the side of the battery with the date purchased. The store manager told me no returns with out a receipt. I just wanted to exchange under warranty.
