whats the diffrence between the yellow top and the red??


  • The yellow top is a deep cycle battery for boats and stereo systems and things of that nature, and the red top is for simple replacement of your car battery. Basically the yellow tops are for more special needs that draw extra power other than what a all stock car would draw.

Interested... upgrades??? Im wondering if i need to upgrade my alternator or anything i JUST replaced the stock alternator after the "check charging systems" light came on and battery was drained...


  • It`s common for the Alternator to go out after plenty of use and easy to test the battery and alternator for propper function but there is no reason to upgrade your OEM Alternator for basic duties ,these batteries pride themselves on a quicker recharge and holding a charge longer than OEM on a OEM system..

Will this work fine with a stock alternator? Is this battery too much for a stock alternator, or would it be better to get a upgraded alternator also?


  • Get an upgraded alt and stop worrying about the batt as it will recharge it so fast you won't care, unless you are pushing a 1000w+ RMS (NOT PEAK) system.

I have a 04 v6 stang. Battery is running low on life. I have one of these yellow tops I got from work. When I looked it up on Optimas website it acted like it wouldn't work with my ride. I see plenty of people are using them. Any thoughts? Is it OK for these 04s?


  • The Optima Yellow Top Performance Battery (79-10 All) should work perfectly fine on your 2004 Mustang V6. The only issues that can arise with this Battery is that it may not sit properly in the stock battery tray because it is larger.

    This is a great battery!

    This battery easily powers everything in my car with lots of aftermarket lighting, dvd player, 2 1800w 12's, 2 1000w amps, 1 800w amp, and 4 400w speakers. The only reason I gave it 4 stars is because it does not fit in the stock tray for my 2000 Mustang GT. The car will not pass inspection now until I fix this.

    Optima Battery

    Old battery was corroding and losing charge causing my '01 GT to not want to start all the time. Pulled it out and wired this one in, instant and full strength start ups. Now thinking of putting Optima's in my other cars.

    Best Deep Cycle you can get...

    Pick one of these up if you want serious cranking amps. It's also the best for any audio or added electronics that have any considerable current draw.

    best ever!

    Awesome battery. starts in just one or two turn overs and super powers everything like it was new. the convertible top goes faster, the lights are bright again, and the horn is as loud as it used to be when I bought the car.

    Awesome Battery

    Bought this battery after the OEM battery starting giving me issues with my stereo amplifier. This battery is definitely worth the extra $$ and now that it is getting cold my car starts up right away, no hesitation. I would recommend this batter. The only thing was the connectors were a little off from the OEM battery but its not a big deal.

    Good product, has some flaws.

    Installed this with the intent of getting more cranking power and stereo power. First of all, it did not fit in the battery tray. I had to pull the plastic side off of the tray to get it to fit then I had to screw the nut down to keep it from getting loose. I did everything correctly and I turned on my car and it cranked like normal. Turned on the sub-woofers and again it dips up and down. Thinking now it could be the fuse to the subs. Probably going to get a performance starter to get the cranking up to a certain point. It is a great product, just wasn't what I expected...

    Must Have For All 2005 And Newer.

    If you have a 05' or newer Stang then you're aware of the battery issue's that no one has really been able to pinpoint. Put this battery in and Wow! Big difference. From being able to listen to the radio while drying off the car to even better shifting.(I have a 07'GT automatic.

    yellow top

    This is one of the best batteries u can get performance wise for this car the main thing is voltage once your voltage drop u loose hp this battery helps maintain that due to its dry cell properties, also to u guys who like to install audio systems its perfect for that.take my word this battery will wake your mustang up.

    good battery

    The battery that was in my car just could not keep up with my subwoofer and amp. I purchased this battery and it does a whole lot better. It did not fit my tray on my 97 cobra had to modify the tray to make it fit other than that no problems.

    Heavy Duty battery

    Ordered this battery and a chrome alternator Tuesday morning, and it was installed on Thursday afternoon. AM's the best on lighting shipping. I have 42K miles on my '07, and with winter coming soon, figured I'd be needing a new battery at some point. So sprinted for the big boy, and looks good under the hood. About a year after I bought my Mustang (new) the insulator cover that surrounds the OEM battery started falling apart and was a real eye sore. So this yellow Optima really was a nice replacement. Put the chrome alternator on today along with the battery, drove around a good while with lights on tunes blarin' and so far so good. They seem to make a good match together. AM IS #1 all way around.

    no better then anything else

    garbage this battery is no better then a regular one. put one in 4 years ago and it already has a bad cell. the only time this battery is better for audio/video equipment is if your alternater isent putting out the amps you need.and as for lasting twicw as long as a factory battery why is there only a 3 year warrenty ,such a waste of money changing to this battery and thinking things are working better is like washing your car and thinking its faster.

    Great Upgrade!

    As Tim "The Tool Man" Taylor would say, "More power! lol. I can now run my sound system and aftermarket accessories without it even breaking a sweat. My only complaint would be that the battery was missing one of the plastic side post covers, and part of included tray was broken off when it arrived. Not a huge deal, but still disappointing.

    This battery is Electrifing!

    I've had my yellow top for about 2 years. It has not given me one problem. I love the side mounts, it makes it so easy to install a sound system without having to bother the car wires. My lights used to dim when the bass would pound hard, but with my yellow top it has nearly stopped the dimming. On rare occasion I still get a dim, but with my old battery it was way worse, and I even tried to install a capacitor. Ultimately, this battery has helped more than anything with proving constant steady power to my car and my sound system both. Also, this battery is a dry cell, meaning it won't leak battery acid if tipped over, making it great to put in your trunk if you want to move your battery or use a 2nd battery for your sound system. I highly recommend this product! It always works, hot or cold outside. I have also left many accessories and lights running while the car was off, not that I reccommend doing that, but I have not had any problems with this battery doing that so far. Ive had a couple other wet-cell batteries that had died due to that!

    Great battery, deep cycle paid for itself

    I was having some parasitic power drain issues and kept killing batteries. I installed this thing and a couple days later I went back to the car to a completely dead battery. Being a deep cycle it was able to come back all the way to full strength with no damage. I've since tracked down the drain and fixed it but this battery is going strong and cranks in new england winters with no problem.
