"Die Hard" is a trade name of Sears Stores. When on sale they can be bought for $59 each or a little more if you do not have trade ins. They are low maintenance batteries and have a very large expansion area to capture the expanding acid when hot. I change mine every 6 years and give the old ones away to the local kids for their cars and have one in my own car for a couple of years. They even come with built in handles for easy handling and a 72 month prorated warranty. Three of them fit great in an 8D box. PS I don't sell'em, I just use'em. .
