Optima Yellowtop Deep Cycle Car Battery Group Size 34/78DT is rated 4.9 out of 5 by 25.
Rated 5 out of 5 by from Outstanding power I replaced another brand of AGM battery in my ParkIt360 which I use to move my car trailers when I disconnect them from my truck. The last battery could never move the flatbed car trailer up the slight grade of the sidewalk. This battery used the immense torque in the electric motor and made the job without my personal efforts. I use Optima batteries in my 8 classic cars as well as my personal driver.

Rated 5 out of 5 by from Great Battery I replaced my old battery with the Optima Yellow Top as I am installing a winch & bumper on my truck & wanted the extra capacity of a deep cycle battery with the ability to be used for multiple starts & stops throughout a day of off road adventure without any problems. This battery has worked very well to fill my needs without any issues or having to wait for it to recharge. I do recommend this battery!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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 from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
