Great battery. Bought this for my boat. This cost less than the auto parts stores, yet is made by the same company (Interstate). Even though the group number was the same as my old battery, this was larger. It wasn't a problem for me, but if you have a tight space you might want to verify the actual dimensions. We took the boat out on the lake and it was obvious how much more power there was to the starter. Another thing to note is that I bought this online with the option to pick it up at the store. That worked fine, until I tried to get my core charge back. The only way they could do that was to cancel the online order altogether then re-ring it up. It wasn't that big of a deal, but they should make it easier to get the core charge back.

I havent had time enough to evaluate these. I hope they last longer than six months. Chain store deep cycle 100$ batteries last three months. Don’t waste your money on them. See photo - junk to the right.
