OPTIMA BlueTop Battery
Our Promise
Ultimate Power, for the ultimate professionals, for the ultimate enthusiasts. And for the ultimate experience. That's our goal each and every day. No matter how extreme the conditions, OPTIMA delivers Ultimate Power. We look for every technological advantage to push the limits of what's possible and leave pretenders in our dust.
We manufacture our own batteries in our own facilities to our demanding standards. To ensure quality and consistency in our batteries, no matter where they are being sold - our batteries are never re-labled or re-spec'd.
Going Farther for Longer
Installing an OPTIMA BlueTop high-performance AGM battery in your boat or RV means exceptional running time and more recharges than you’d get out of a traditional battery. It’s the perfect marine battery for boats with trolling motors, extensive electronic systems, and works well as an RV battery for RVs with creature comforts that tend to drain batteries quickly. On top of providing outstanding vibration resistance, the BlueTop efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. This means more time for fun. Again and again. This flexible boat battery and RV battery is ideal for those who need a sure-starting, strong-cranking, maintenance-free power source.
- Up to three times more recharges than other marine batteries
- More than 15 times the vibration resistance
- Spillproof, mountable in virtually any position
- Maintenance-free
- Works well as a boat battery or RV battery
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. No one knows how to build the highest quality and best performing spiral-wound batteries better than OPTIMA.
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 D31M BlueTop is designed as a dual purpose battery, both starting and deep cycle for people who need a sure-starting, strong cranking, and maintenance free power source for their boat or RV, even in harsh conditions. 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. This battery is designed to be used with recreational vehicles or boats with large accessory loads.

I purchased two of these batteries from Amazon, but they ended up shipping me a total of five due to shipping damage caused by inadequate shipping materials. This 60lb battery was typically shipped with zero protection, just the cardboard box. The 'large plastic bubbles' you see in lots of Amazon packages was used once, but not surprisingly, they popped and were deflated by the time the battery arrived. Brown paper was used a couple times...it was flattened easily and offered zero protection. Twice, styrofoam end caps were used (only one piece per box), though it was a styrofoam piece designed for a smaller battery...this worked enough for me to accept the products at least. Of the five shipments, the three 'rejects' had cracked plastic at the bottom of the cells...the first, I didn't notice until charging and a little acid leaked out. Once I knew what to look for, it was easy to spot. Amazon was very cooperative with the returns, but it was such a waste to see three of these batteries head straight to recycling when a little care and intelligence could have prevented that.
If you're feeling lucky and you order one of these, be sure to check the plastic very carefully for cracks (it'll be easy to spot if you're looking for it)! Pay special attention to the plastic at the bottom of each cell.
This purchase was a second blue top D31M. I use two of these batteries in parallel to power a 2000 watt inverter. I tested it by placing a 1500 watt load on the inverter which drew 137.5 amps from the two batteries in parallel. They were able to sustain this load for 27 minutes. That is like cranking a 6 cylinder engine for half an hour. I previously used marine deep-cycle flooded-cell batteries for my inverter but they would only last about two years and I constantly had to check and add water as well as clean corrosion from the terminals. The bottom line is even though you pay more initially to buy an Optima battery the long life and power delivery quality actually make it cheaper than other batteries when you divide the cost by the number of years of service.
Will update review when I determine if the battery works.
Well it is two days latter, and though beat up, the battery appears to work. Now I am just not sure how long it will work, nor what the return process will be if it fails. I still won't buy another battery through Amazon without assurance of an adequate packaging process and a customer friendly return process.
NO HANDLE - My biggest disappointment is there is no handle on this battery. It weighs 60 pounds and I have to lower it into my battery compartment without the benefit of a handle, putting strain on hands and back. It slipped out of my hands and dropped as I was putting it in, fortunately nothing was broken. Now any time I need to remove the battery to get to my bilge pump I can look forward to dealing with this issue every time
MINIMAL HARDWARE - The battery comes with only two nuts and no split-lock washers. I also purchased two LiFEPO4 batteries from Lossigy. They not only included a handle and hardware with split-lock washers, but included an extra set of hardware, plus they included two very thick gauge battery cables.
This is a high-quality battery. For $430 you would think Optima could include a handle and plenty of hardware. Whoever it was at Optima that decided to save a few bucks in cost made a poor decision.
