Rated 4.6 out of 5 by 21 reviewers.
Rated 4 out of 5 by technology of AGM Many people think the AGM batteries are best for mounting location benefits. Although that is a benefit because they are non spillable, it is more about the way AGM batteries give up or deliver the energy stored within. The surface area of the Optima Red Top spiral technology is enormous compared to a traditional "wet" lead acid battery.The red top optima is able to receive a charge quickly too. The daily driver will benefit from the quick recharge and stable power delivery of this battery. Texas heat is brutal and the AGM works better than lead-acid. The price seems high until compared to benefits and the fact that the lead inside is purer. AGMs don't have to support hanging from tabs in a liquid like traditional plates do, those consist of alloys which reduces the reaction. Phone chargers, car audio, and other accessories will benefit from consistent stable power delivery. The 34/78 posts offer multi-purpose connections for fuse blocks or jumper cables without the hassle of trying to get them to stay on the little side post terminals. July 13, 2015
Rated 5 out of 5 by exactly what i needed great price and quick delivery. May 1, 2015
Rated 5 out of 5 by Best battery and best price on the market I have used Optima a Redtop Battery for my off road Jeep for years, always thought they were the best. Never even thought about an Optima for my work truck. This time I was checking around for a replacement for my truck and looked at the Optima. Liked what I saw on reviews and then in checking with suppliers, I found that Pep Boys were offering 30% of their initial price. That was even more than 30% lower than any other parts place. Great product and outstanding price. January 11, 2015
Rated 3 out of 5 by Put in truck and it started, Great Old battery was losing its charge put this one in and the truck started up, and it's continuing to start every time. Could have came with better vehicle specific installation instructions, comes with every adapter for all kinds of vehicles, and couple options for Ford. December 25, 2014

Rated 5 out of 5 by My 2nd Optima Battery & it works fine Although the Red Top Optima Battery had to have a Hold Down Puck Adapter for the installation in my Silverado Truck it came with the battery & was a cinch to install. Have had a Red Top Battery in my Jeep CJ5 for over 6yrs & it is still going strong. August 11, 2014

Rated 5 out of 5 by Best Battery on the Planet This is my 2nd optima battery purchase. The first one lasted approx. 7 years. and it really didn't go dead, but I was experiencing a weak start on occasion so I decided to replace it before I got stranded. Highly recommend the optima battery. September 23, 2013
