Rated 5 out of 5 by awesome battery great price fast installation excellent product!!! February 3, 2015
Rated 5 out of 5 by Excellent Product Excellent product. I have used this product previously. January 16, 2015
Rated 5 out of 5 by this product stands up to the challenge. This is a great battery. It work well if you have allot going on in your vehicle. Ie. Powered everything, stereo systems or just simply more power. January 1, 2015
Rated 5 out of 5 by powerfull battery Upgraded from the red optima to the yellow. My red optima was 11 years old and was the best battery I have had in a vehicle but was starting to fade. The yellow optima has more power with the key off. I have many accessories which require more power. This battery takes care of all my additional power needs. December 23, 2014
Rated 5 out of 5 by Pep Boys was great at honoring Warranty ! I've used Optima batteries in all my vehicles, in my Vette and when I was in Alaska in my Navigator ! Can't beat them !!! November 29, 2014
Rated 5 out of 5 by Best Battery Anywhere I was tired of going through cheaper batteries every couple of years. Decided it was time to spend the money on a good battery, and with the discounts I got through Pepboys.com, it didn't hurt the wallet that bad. Would recommend an Optima battery to everyone!

Rated 5 out of 5 by So glad that I chose this one! This Yellow Top is a phenomenal battery! I am glad I decided on the purchase. September 19, 2014
Rated 5 out of 5 by Awesome Battery I would not hesitate to buy this battery. They are built like a truck and they always start. You really need this in today's vehicle that has a ton of accessories that drain your battery all the time. It may be expensive, however you will get your money's worth in both longevity and safety. You do not want your family stuck somewhere with a dead battery. These things will start even if you leave the lights on for a week. August 19, 2014
Rated 4 out of 5 by Good battery and only battery I use for my vehicle Great battery August 11, 2014
Rated 5 out of 5 by Optima Yellow Top Batteries The Optima yellow top battery is a great battery if you have any added accessories to your vehicle. I use the Optima battery because of my car audio system, and each battery that I've had has lasted me 4 to 5 years. They are the best bang for the buck. March 14, 2014
Rated 5 out of 5 by Battery works Great!! Due to the extensive electronics in my vehicle, Yukon Denali, the Yellow Top battery made everything work better. I know it seems crazy, but my mileage did improve. The battery in the Denali was working fine but I swapped in the Yellow Top and moved the Denali battery into another vehicle which needed a new battery. I was so satisfied, my son with an extensive sound system in his Firebird did the exact same thing with his vehicle. The Yellow Top does seem to be necessary for high electronics drain. I believe it helps the sensors throughout the vehicle maintain a constant voltage and doe not require a large capacitor that some amps need to maintain constant voltage. Just guessing, but I do believe what I see. October 31, 2013
