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.

  • 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...

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.

    Optima Battery

    October 16, 2010

    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 ever!

    December 11, 2010

    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

    December 07, 2010

    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.

    January 26, 2012

    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.

    January 30, 2011

    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

    August 05, 2012

    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

    February 13, 2011

    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

    September 06, 2012

    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.
