Here is what happy customers are saying:

So far great battery! I’ve used Optima for about 15years now through a variety of cars, trucks and Jeep’s. This installed in my 07 Jeep Wrangler JKUR. I purchased this because I need the extra posts to connect my winch.

Best boat battery I’ve ever bought. I use on our runabout and we never have to worry about starting, radio, or any of the electronics. So much better than the cheaper batteries I had to replace after 1 or 2 seasons. My battery from 2008 is still running strong. Stored it on the boat disconnected all winter long and it was still at 12.5v and started the engine no problem. Just bought a second one (going with two of these vs one starter and one old style DC). Amazon super saver shipping delivered it to my door in 2 days! Love Optima and love Amazon to buy them!
