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?

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.

Product Description

Optima D34M 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. Refer to the user guide for troubleshooting steps. Case Material: Polypropylene

    I researched rv batteries and this brand got good reviews. Some complained quality was not as good since production was moved out of U.S. That I will have to see as the years ( I hope ) pass. Anyway, the battery fit nicely into my rv and thus far it has functioned as advertised. I am happy with it.

    My boat has had these batteries for five years. I have a 24-volt trolling motor so I use two batteries. I fish about three times per month and they are heavily used. The batteries started losing their charge towards the end of the day so I decided to replace them. I save about $45 per battery by buying them from Amazon versus a local shop. I read the reviews on Amazon about some damaged batteries due to poor packaging during shipping. I chose the Standard Packaging. One very frustrating issue was when I tried to contact Amazon. They have "Frustration Free" shipping and "Standard" shipping. I tried to find out which was more protective. After four emails from them, I gave up. The people responding to my request did not have a clue how to answer my question. Well, the batteries showed today in VERY hard/rugged corrugated cardboard boxes. These boxes were built correctly and did a great job protecting my batteries,

    In addition to the high quality and vaulted durability of Optima AGM batteries I really like that they provide two connection points for negative and positive. This eliminates stacking of several connections on one post. If this lasts 6 years on my sailboat it will be money well spent.

    I am like a lot of people wanting to save a few bucks. Unfortunately when you buy economy batteries you often lose money in the long run. This was the case for me so this time I went with a recognized industry leader. Optima batteries are top of the line and the difference in power and run time increase with these batteries is amazing. One word of caution. These are AGM batteries and they must be charged with a charger programmed for AGM batteries. If you use the wrong charger it could damage or destroy the charger and/or the batteries. Fortunately the onboard charger in my bassboat is designed to charge all types of batteries and a simple change of a screw in sensor ensures I will have these batteries in service for a very long time. When these batteries were delivered one of them was upside down. You can mount AGM batteries at any angle because there is no possibility of losing acid from the battery. The acid is soaked into fiberglass pads inside the battery. They were fully charged when I received them and I fished 2 long days with them before charging for the first time. I would highly recommed these batteries for any marine application.
    For the fishermen who have not used AGM battrries a word of caution. AGM batteries provide full power until they are dead. Most batteries will provide less and less power as the charge is depleted. That is a positive thing. Just know that when your battery loses its charge you have no notice. I charge every time I go fishing so I dont see this as a problem..
