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 1990βs.
What's the difference between OPTIMA RedTop, YellowTop, and BlueTop Batteries?
|
|
|
---|---|---|
RedTopFor 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. |
YellowTopUse 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. |
BlueTopThe 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. |
Product Description
Optima 25 RedTop is designed to deliver high power cranking ability even in harsh weather conditions. This battery is great for heavy use by hot rods and off-roaders with its leak-proof, high power, and starting ability. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The higher reserve capacity gives you a longer shelf-life to give you the power when you need it, where you need it.

~~~~Update: Aug 28 2019~~~~ There is some hope for resolution. Optima batteries don't charge well if they've been drained under 10 volts. (Conventional car batteries can't pull voltage up that that low.) So, Optima customer support suggested I charge the battery in parallel with a good battery, which will bring up the voltage to a level where a charger can take over.
~~~~~Update Sept 3 2019 ~~~~~~
I was able to get the battery charged back up to 12.35 volts, and it's holding steady.
These Red Top batteries cannot be charged with a battery charger if they get below 8 volts or so. So, Optima customer service stated I needed to hook the dead battery up in parallel with a good battery, and then do the charging again.
This worked. the dead battery got up to 11 volts over a couple of hours of parallel charging. Then, I charged it on its own overnight, slow charge, and it's up @ 12.35 volts.
So, there are a lot of people who reviewed this battery high. and I haven't given up on it. I know now, with this battery, it can't sit in a car unused for 1-2 weeks without needing some extra TLC.
On the bright-side, Optima customer care were helpful. And they told me that if the battery could not be charged back up, they would stand by their warranty, and work with Amazon to get a replacement. That's pretty cool.
3 stars = not a great product experience, being without a working battery for 1-2 weeks.
but an extra star because Optima customer service was great.
1) I called Amazon customer service and they informed me that I had to call Optima to handle the warranty claim.
2) After spending some time navigating the Optima customer service line, I was informed by Optima that Amazon needs to handle the warranty claim and that they frequently have "misinformed" Amazon reps directing the claims to Optima. Optima has repeatedly asked Amazon to put a "pop-up" notice for the Amazon reps so that they realize that indeed Amazon should be handling the claim. Looking at the product description, I still see confirmation that the Optima reps are correct when Amazon is the seller (as it was in my case) "Please contact Amazon Customer Service with your warranty claim. For purchases from Amazon Merchant sellers please contact the seller directly for warranty support."
3) So I call Amazon again, spending close to an hour on the phone with a rep that insures me that they will take care of the problem today. Sure enough, after repeatedly confirming that : yes indeed there is a 3 year warranty, yes, indeed I bought the item from Amazon and not a merchant seller, I am abruptly told that they can't either replace or refund the cost as "it has been too long from purchase date" (still well within the 3 yr period, mind you. At this point the Amazon rep asks me to write an email detailing the conversation with Optima (which I do). 1 week later, absolutely still no response from Amazon.
I have gone to a Battery Dealer who used to be an Optima reseller (incidentally, ... the battery load test indicated a failure with a voltage of 11.5 V) and the rep mentioned that they no longer supply Optima batteries as they have begun to fail at a faster rate in recent years (he attributed it to shift in manufacturing location to a lower cost country). He still recommended that I try to get the Optima warranty honored.
The battery worked fine for ~2 years, but I would not purchase this product again as I wouldn't trust the warranty.
