Review & Installation Video

Premium Starting Power. The Optima RedTop high-performance AGM battery is the ultimate high-CCA (cold cranking amp) starting battery designed to deliver the strongest 5-second ignition power for a reliable start-up every time.

Superior Construction. Optima uses a patented SpiralCell construction that has faster recharging capabilities, more than fifteen times the vibration resistance, and twice the life of a standard automotive battery.

Versatile Design. Optima designed the Red Top battery to be maintenance free and completely spill-proof with dual terminals so that it can be mounted in any position necessary, great for custom applications.

Technical Note. Battery may be slightly larger than stock tray.

what would someone be looking for if they want this battery or the other? as you can see im not sure what these terms mean in the performance description of ether battery so i basically need a complete breakdown of both for ex. the red top is better at ... the yellow top is better at ...

  • The red top is for cars, trucks, SUVs, and hot rods in general and provides a 5 second burst of power for reliable start up. The yellow top is for cars running a lot of serious electronics (stereo) and higher amp alternators. Both are designed to be mounted in almost any postion, unlike traditional batteries that need to be mounted top facing up. The average car only needs the red top.

Does this battery add any horsepower?

would this battery fit 03 roush stage 2? whats better the optima red or the yellow one?

  • Unfortunately, the Optima website does not indicate that they produce a battery specifically for the Mustang. That being said, I seriously doubt they would advertise it unless they were sure. It will fit your Roush Mustang. Yellow top is designed for cars running a high electrical load, such as serious stereo equipment. They red top is for the average street rod, SUV, trucks, and high compression motors by providing a strong initial burst to get things rolling. Unless you added a lot of electronics, the red top is good for your car.

Is the battery chargeable? I have a AGM capable automatic charger. My current, cheap autocraft battery is not rechargeable and I don't want to make that mistake again. My car can sit weeks at a time and I want to be able to charge or float charge if I need to.

  • This Optima Red Top Performance Battery produces 800 cold cranking amps.


I have a 2010 Roush Mustang with the 4.6l V8. Will this battery fit in my car? I checked on the Optima site and it says they don't make a battery that will fit my car, yet on your site it says it will. I don't drive my Mustang very often and it sits for a week or more at a time and when I do drive it, it's usually just short trips. So there is a heavy load and little time for the alternator to replenish the charge. I need a battery that can stand up to this.

  • The Optima Red Top Performance Batteries are fairly universal and should fit in most cars. This battery should fit into a 2010 Mustang with no issues.

    fit is not nearly as wide as stock. various spacer included for solid fit, snug with tiedown strap. posts are bit further forward than stock so was bit tight without redoing cables. height is definitely taller than stock and pretty snug against hood. solid power now, great starts and power for all accessories.

    Great battery, fit my 2010 gt tray w/no issues. However the posts r backward I had to find slack in the harness to make the terminals reach. Lost one star for this no problems after 2 weeks.

    Never got to experience Optima

    I purchased this Optima battery in hopes of it being better than the standard car battery. Unfortunately for 2010 mustang owners the terminals are reversed and could not reach the battery. I tried turning the battery around as much as possible and in the end I just had to go with another option.

    Works but fitment issues

    Car fired right up! Only down side is the battery is taller than the stock one so the plastic battery covers I bought from here don't fit anymore which really sucks since u had them custom painted! Once the positive terminal is on and you shut the hood it hits the underside of the hood.

    Posts on Wrong Side

    The only complaint I have is that the posts are on the wrong side. I should have inquired on where the positive and negative post were because my terminals are opposite of them.

    Powerful battery, but the design had the terminals swapped.

    Great performance battery upgrade! But when I went to swap it with the dead stock one on my 2010 Mustang, it wasn't until I secured it in that I realized the and - terminals were swapped around. The cables could not reach them. Easy fix was to flip the battery around and bend the black end cable straight to make it fit over the top. But I would definitely recommend this product!

    Powerful battery

    After letting my Mustang sit for the winter, my battery was completely dead. No charging would bring it back to life. So, I decided to spend the change and get a battery that has a great name, warranty, and looks. I decided to go with the Red Top and upon just taking it out of the box and installing it, I was happy. It fired my Mustang right up, out of the box, and quickly. I also bought the PA performance terminals which make a nice combo. I bought this battery knowing that it wouldn't fit my factory battery tray, which is fine, a little modification never hurt anybody. So, so far, so good. This is my first Optima battery, and I'm hoping it continues to impress.

    The battery is taller than the stock battery, and the terminals are on the opposite side from stock. After rerouting the cables, and adjusting the positioning of the battery, I was able to make it work. It works as advertised.

    Optima Red Top Battery

    Comes with several adapters for different battery trays to fit multiple vehicles. I was able to install it in my 2009 Mustang with the factory hardware and no adapters needed. Looks great and adds confidence the car will start after sitting up for a few weeks without use. Worth the extra money if it lasts longer than the typical auto parts store brand.

    Great Battery

    Ive been wanting one of these for a while now and finally picked one up. It is heavy. And they do not fit all the way in the tray. I had to squeeze mine in. But it shouldnt move at all. Optima does make a slightly smaller one that should fit. But on any 94-04 at least, you will need to do some finageling to get it in there. But its a good battery so it is worth it

    Good Battery

    My battery died and I wanted to upgrade. Finally decided on this and found a good price and knew it was reliable to order from AM. My car started right up and feels good. Install was ok. The battery didn't naturally fit the current tray so I forced it in and clamped it down. The shipping box could've used some extra cushioning as the battery got a bit banged up. After initially being disappointed that the battery wasn't treated like a princess, I quickly got over it and now I'm happy with my purchase.
