User questions & answers

Question:	will it fit and work with my ford
Answer:	Most Fords have 65 group batteries in them some have 34 group all that don't matter what matters is what side the positive post is on. If the positive is on the right side then you will need a reverse post battery. I believe a 9020-164 has a reverse post. But for the battery box size these optimas are universal and will fit almost any battery box in the western hemisphere. So just take a peek at yours if the label is facing you and red on right then you have a reverse post, but if not then the standard 34/78 will fit perfectly. On the optima box it's self there is a packaging cover that comes will all optimas and. There is several adapters to make the 34/78 battery fit most cars and trucks.
Question:	Right now i have 2 yellow tops, 1 under the hood for engine, and 1 in the trunk for my sub. would i be better off putting a red top for engine/4eat
Answer:	From what I have been told---the Red top has higher initial cranking power and the yellow top has better storage capabilities---I have them on my trailers.
Question:	Does the optima battery come with a warranty
Answer:	Optima batteries are made in Mexico. They only honor the 36 month warranty on the 1st battery, not the replacement. Save your money.
Question:	Ok so I have a aftermarket stereo double din and big speakers. I read yellow top was better for my use. Is this battery good too
Answer:	The Yellow Top might be better for your needs. Red Tops provide more cranking power. Yellow Tops provide more reserve if you listen to your stereo with the engine off. I had a Yellow Top in a car with an underdrive pulley on the alternator and a 1,200 watt system (RMS not that peak rating crap either) and that battery lasted through 5 years of torture.

Gentlemen, Start Your Engines

The RedTop high-performance AGM battery is the ultimate starting battery designed to deliver a powerful burst of ignition power for a reliable start-up every time. It will withstand hard launches, extreme corners and is race proven for every road every day whether it's used as a truck battery, automotive battery, or for other applications. Its reputation as a truck battery or automotive battery is unsurpassed.

SpiralCell Technology

At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.

The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored.

OPTIMA has built over 100 million individual spiral cells since the early 1990’s.

RedTop

For normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed.

This would describe most stock vehicles, including: automotive and RV underhood starting, heavy equipment where starting is the primary function, and diesel vehicles without aftermarket electronics.

YellowTop

Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators. This can also include vehicles with a lot of factory electronics such as power sliding doors and a DVD player. Examples also include: racing vehicles without a charging system, dedicated drag racers, diesel powered vehicles with aftermarket electronics, and vehicles with inverters, winches, or other accessories.

BlueTop

The BlueTop starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. Use a BlueTop starting battery for marine applications and RVs when the battery's only function is engine starting.

The dual purpose BlueTop (light gray case) can be used for both starting and deep cycling -- it is a true deep cycle battery with extremely high cranking power. Uses include: trolling motors, marine applications with heavy electrical accessories, and RVs.

User questions & answers

Question:	which of these batteries would fit into a 1979 MG midget, 2 door convertible
Answer:	I believe all of them would fit into a 1979 MG Midget. They're not that small.....
Question:	This says unboxed. How is it packaged? Does it come with all the accessories in the retail box including spacing adapters
Answer:	Yes, mine came with the appropriate spacers for my particular form factor. I have a 2001 f-150 and I am sure glad it came with the spacers because I had to use one of them to get it to fit. I comes in a box with the spacer inside of it. So as far as the spacers go, Optima thought of everything! I am very pleased with the product!
Question:	does this battery come fully charged
Answer:	Mine came fully charged, my vehicle indicates 12.0V (engine not running) and ~13.8 to 14.0V (engine running). I keep this vehicle hooked up to a Deltran Battery Tender and it did not take too long for the Battery Tender to register Green (fully charged) once hooked up (~a few hours or so).
Question:	I see concerns about an Amazon warranty after 1 year yet the warranty noted in Amazon for the red top is clearly 36 months. What's the real deal
Answer:	It's 36 months through Optima. Unlike going back to the parts store what you have to do is file a claim with Amazon customer service. They do all the leg work from there. So here is the issue you have to decide if it's worth it or not. It can take a week between customer service contact, optima approves, new battery received. Can you make it a week without a battery??I have only seen one issue with an Optima battery back when I worked at a marine dealer. We sold a hundred or so a year (was there 2-1/2 years). Mine is only a couple months old, but I did accidentally kill it installing amps, subs, stereo, and it recharged and has no issues. Hope this helps.

User questions & answers

Question:	Can these be wired in series, I know you can buy 12 volt but 6 volt wired in series work much better in RV's
Answer:	Wired in series gives you 12vdc. Wired in parallel gives you 6vdc with more current. My scissor lift uses 4, 6vdc batteries wired in series to get 24vdc at 200 amps.
Question:	hi will this battery fit a 1955 series 1 chev 6 cyl pick up
Answer:	I have the 6 volt version in my 1952 Chevrolet Hardtop. The battery will fit in the battery box at an angle. It is longer than the standard GM battery but much narrower, therefore you can angle it in the box and support the hold-down at the opposite corners and it will work fine. I had my Optima for 6 years in my Chevy.
Question:	Does the description's height of 7 13/16" (7.8") include the terminal posts? If not, what is the height of battery from base to top of posts
Answer:	Hi BrianI measured my battery roughly using a cheap tape but here goes. I measured the height of the plastic casing at approx. 7 1/4 by 10 inch long and 3 1/2 inch wide but from the bottom of the case to the top of the post is approx. 8 1/8 inches. Strange enough this battery would lie flat on it side in the battery tray with the posts towards the engine in my 40 Ford. I could stack two of them on their side if I had the right cable hook up. Nice battery, small for the standard tray but has decent power and holds its charge very well just sitting in garage 6 months. Hope this helped somewhat.Wayne

User questions & answers

Question:	i am looking to use in a race car with no charging system, we manually charge between races, would this be better than red top
Answer:	My short answer is Yes - the yellow should be better. Deep cycle type batteries do better than regular batteries. They can be run down and then charged back up without consequence, whereas the red is not a deep cycle, so it might not like it as much.Heres my long version. The yellow top has the properties of a deep cycle where it's the better type to use if you have an audio/video system that you sometimes run with the car turned off for a long period of time (and it gets charged back up later when running), so from that perspective, it sounds pretty similar to running it in a race car.But here's where I would be out of my element a bit. It seems to me that it would depend on the type of race and what the power requirements would be. If it was just a drag race where it's starting off charged, and then run for maybe 15 minutes while getting ready for an 11 second run, then I bet either would work well and the determining factor of the winning choice would be weught. And maybe even an entirely different and significantly smaller (lighter) battery altogether might be a better choice. But your question was about yellow or red. I think their weights are pretty similar, so I think you'd get the best performance from the yellow. I believe a deep cycle is made to be more durable and provide sustained power longer (that's the general purpose of a deep cycle from what I remember reading). And they don't have issues being run down and charged back up, so the yellow deep cycle should be better for the guy at a car audio video show, or a race car driver, or i bet even a person that just has a failing alternator, but a short drive to work and a garage and place to park and charge his battery each night.The yellow is a better battery, and I was very pleased with the price I paid for mine too through Amazon. Hope that helps!
Question:	how many amp hours? not cca
Answer:	I have one in my Tahoe and if the voltage drops below 11.5 dcv it will not start. keep it at 12 to 14 Volts!!
Question:	If Amazon is not an authorized dealer what is the impact on the manufacturers warranty? If any
Answer:	Amazon has sent me two emails saying that they do not honor the 36 month warranty. Mine failed after less than 2 years. Very disappointing for a $300 battery.
Question:	Is this battery good for operating temperature around -15 to 20 Degrees Fahrenheit , and whats the difference between blue , yellow and red tops
Answer:	Blue is for marine use. Yellow top is called a "deep cycle" battery and is for high demand use such as vehicles with high wattage sound systems or electrical systems that draw a lot of power like off-road lights, snow plows, etc. The red top is for most vehicles on the road and the one I've had the best luck with. The yellow top, if not cycled and/or charged properly runs a higher risk of shorting out, not common, but possible (I did it to one) but I've never had a problem with the red tops. As for the temperature range, it's not going to be much different than a standard batter. Their advantage is they use a a spiral "cell" as opposed to plates that standard batteries use. In theory, their life cycle should be longer as there is less of a chance for the batter to short out as plates are typically close together where in the Optima, the spiral is in a tube/cell of it's own. Hope that helps.

Product description

Battery

• Note: Refer a user manual before use
• Durable design protects against the worst enemy of a truck battery – road vibration (compared to standard flooded batteries)
• Calcium alloy is optimized to produce a fine grain, corrosion-resistant grid, maximize cycle life and minimizes water consumption for battery durability
• Fully charged ACDelco Batteries (OCV is >12.5) should be stored in an upright position at temperatures between 32°F and 70°F. When a battery is stored, a very slow chemical reaction takes place between the plate materials and the electrolyte, causing a slow discharge. This reaction, called a self-discharge, occurs more rapidly at higher temperatures. Therefore, it is not recommended to store next to a furnace or other heat source. If an ACDelco Battery is completely discharged, the electrolyte will freeze when stored below 30°F. To prevent electrolyte freezing and battery damage, do not store ACDelco Batteries below 30°F if their OCV is less than 12.5 volts. Check battery every 2 months and maintain a voltage of 12.4 volts or higher

User questions & answers

Question:	Does this battery ship charged? Can it go straight from Shipping into the car without any charging
Answer:	You should ALWAYS charge a battery before installing it. Most are delivered below 100% charged. You need to use a microprocessor based smart charger that is capable of charging an AGM battery! Do not charge an AGM (absorbed glass mat) battery with a traditional SLI (starting lighting & ignition) lead acid battery charger. Batteryminder has a very affordable smart charger that will safely charge AGM and SLI. Batteryminder model 1500. Good luck
Question:	Will this fit a 2009 prius without modifications
Answer:	I bought this battery because the previous response to fitting on a 2009 Prius. It does NOT fit in my 2009 Prius- it is 1.5 inches too long. I am hoping to return it.
Question:	Is this battery fits in 2008 smart key prius
Answer:	This is a perfect fit for a 2008 Toyota Prius. I installed it a couple of weeks ago and it has performed fine. It seems like the car's fuel economy went up a little also. I watched a couple of videos online that showed installation of battery and would recommend that if your during a self installation.
Question:	What is a smart key
Answer:	A Prius equipped with smart key entry sends out a radio signal looking for a remote key. When you approach your car with the remote on you the car senses it and allows you to open the doors and start the car with out a key. This is important for the battery because, unless you disable it, the car transponder runs constantly and you need a deep discharge battery. It is recommended that you disable smart key if you are parking longer than a couple days to avoid depleting the 12 volt battery. The disable switch is on the dash below the steering column. This is fully described in the owners manual.
