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.

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.

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

The heart of the VMAX is the unique physical and chemical structure of its plates. The special treatment and manufacturing process they undergo gains them unique reliability, strength and high performance far exceeding those of other Pb-Ca plates used in similar looking products. Using our specially designed Absorbed Glass Matt (AGM) between the VMAX plates, adds to it many physical and electrical advantages that make it superior to the Wet Lead Acid Batteries. This also maximizes the VMAX resistance to shocks and vibrations. Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as “non-spillable and non-hazardous”. A tough Tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAX Tanks are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application. est 4-9 HOURS (40LB/18LB) RUNNING TIME WITH 50-60% DEPTH OF DISCHARGE ON 18-40LB TROLLING MOTORS. (NOTE: LONGER EST. TIME APPLIES TO THE SMALLEST LISTED RANGE OF TROLLING MOTOR POWER WHILE THE SHORTER EST. TIME APPLIES TO THE LARGEST LISTED RANGE. DIVIDE EST. TIME BY 3 WHEN OPERATING MOTOR AT WOT WITH 100% DOD (Depth Of Discharge), OR BY 5 WITH 60% DOD) CHECK OUR FULL LINE OF VMAX MARINE BATTERIES FOR LARGER TROLLING MOTORS OR LONGER RUNNING TIMES.

• Dimensions: L=7.7" W=5" H=6.1"
• Also avilable as a battery kit: http://www.amazon.com/gp/product/B00HOUCLWE
• Heavy Duty Grids: VMAX heavy duty lead tin alloys provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges.
• Maintenance Free Operation: There is no need to check specific gravity of the electrolyte or add water to VMAX tanks during float service life. In fact, there is no provision for this type of maintenance.
• RECOMMENDED CHARGER: VMAX BC1204 12V 3.3Amp

User questions & answers

Question:	are the connecting posts 3/8 inch size lugs
Answer:	Mine came with thumbscrews (bolts) that have a 1/4" thread size and a 1/2" shoulder on the bolt. The battery lug is about 1/2" in diameter and is tapped for the bolt. The battery lug is almost flush with the top of the battery.
Question:	how well will this work for my watchdog backup sump pump system
Answer:	not familiar with the sump pump system. If it is 12 v dc. I have run almost continuously a 55 lb trolling motor on it for over 4 hours and it still had power.
Question:	I want to purchase this battery for my storage room,that doesn't have outlets,Which inverter power supply to use ? Thanks
Answer:	doesn't anybody realize this is an electrical item and in order to answer these questions we first need to know the amperage or watts that your device uses and then AND ONLY THEN you can answer all these questions. Take the amperage draw of your device and multiply it by the hours you will use the device per day and this will give you the amp-hour rating of the battery you will need to run your device for a day. Make sure you multiply the answer by two since you don't want to discharge the battery more than 50% to extend its life. I can't believe that the people who own these electric trolling motors do not know the amp draw and refer to them by pounds thrust. This does not answer the question of what size battery you need for a specific run time per day, hour or various days.
Question:	Why should I get this battery instead of a considerably less expensive Universal Power Group (UPG) battery with the same ah rating
Answer:	VMAX batteries will be better for several reasons. Even though the amp hours are the same, all VMAX USA batteries feature high performance military grade plates. Also, the metal plates used in VMAX batteries are thicker. This results in a higher quality, longer lasting, and heavier battery (For example the VMAX857-35 weighs 25 pounds, the UB12350-D5722 weighs 22.6 pounds, both are 35Ah). The VMAX also includes a standard carrying handle, and features a tough and durable outer casing made of extra strong ABS plastic.

User questions & answers

Question:	I have the gen 4 when the lights show green it's still showing 14.56 volts is that normal
Answer:	Yes
Question:	Can I juse the NOCO GENIUS GENM2 charger with a Honda EU2000i Portable Inverter Generator
Answer:	Yes. That generator has a 120v outlet just like a house. I think the outlet is good for 20amps. Only thing would be you would need to run it long enough to power the charger so it could charge the battery it's hooked to which could take a while to properly charge.
Question:	Will this charge 6volt deep cycle golfcart batteries
Answer:	No Sir-This is only for 12 volt batteries-The model you want is the. Genius G3500 it will charge 6/12 volt batteries @ 3.5amp for around 50 bucks it will bring that battery back to life.
Question:	How dose it mount to the hull/boat...i dont see tabs for mounting screws
Answer:	On the corners are holes - drill those out and then use 6" lag bolts (as mentioned in another answer), or drill some holes in the hull and run zip ties. Larger holes make running zip ties easier. Note: while adding the holes in the hull will cause leaks, this unit is waterproof to 3 meters so it will work as your boat is taking on water. But it will be mounted well.

User questions & answers

Question:	is there a battery inside the box or i have to buy it separately
Answer:	You have to purchase whatever battery you want separately. There is no battery in the box.
Question:	Can I use the cigarette lighter port to recharge the battery? I use a cig lighter connected to a charge controller(connected to solar panel) on my other rechargeable battery that's not in a box
Answer:	You can, but slowly and carefully. It will take a long time because cig ports are usually rated to 10A max. If you supply more amps, you'll blow the fuse or burn the port. 80 AH battery (for example) is desirable to charge at ~20A, if it was deeply discharged.
Question:	What are the true inside dimensions of the box? (the listing says 14.9 x 8.7 x 15 inches" but doesn't specify outside or inside
Answer:	I just received my MinnKota Power Center (7-26-2016), I'm happy with it. The exact inside dimensions on the bottom where the battery will sit is 13 5/16" Long x 7 1/4" Wide x 8 7/8" Tall, add another 1 13/16" to that height measurement for clearance for your battery's terminals inside the lid. These inside dimensions flare up from the bottom giving you 13 7/8" Long x 7 3/4" Wide at the 8 7/8" point from the bottom. My Group 31 Vmaxtanks Vmaxslr125 AGM Deep Cycle 12v 125ah SLA battery sold on Amazon fits perfectly with 1/2" clearance at the bottom on length and width.
Question:	Can someone please tell me the use of the contents (two rubber strips & metal screws) in a plastic packet that came with the power center
Answer:	It for holding the battery in place (rubber strips are screwed in to some thing solid and straps are feed through them and around battery)

About Us

In 1934, O.G. Schmidt invented the first gear-driven electric trolling motor in Fargo, North Dakota. The idea took off with anglers looking for more boat control, and Schmidt named the growing company for the land he called home: in the heart of fishing country, on the MINNesota-North DaKOTA border, Minn Kota was born.

Since then, we haven’t stopped evolving and innovating. From foot pedals to composite shafts, and variable speed controls to GPS-controlled trolling motors.

Today, our trolling motors help you plow through stump fields while our i-Pilot systems control your boat at the push of a button. Our Talon shallow water anchors lock you to a fishing spot like nothing else. We make marine battery chargers that keep everything running from sunrise to sundown, day after day, year after year. And with a full line of Minn Kota parts and accessories to support it all, we’ve got your back.

User questions & answers

Question:	How many battery and what model of your product batteries needed for ac 220 volt for motor 3.49 amp to running it by inverter 3000 watts for 12 hours
Answer:	The answer is way too many. 220 volts at 3.49 amps means 64 amps at 12 volts, which is the very near the 66 amp rating of the battery. Since the battery should never be drained below 50%, the answer is you would need two to run your motor for 1 hour, or 24 to run it for 12 hours. You'd be better off looking at some 8D lithium batteries. They hold 255 amps and can be run down to 20% of capacity. Please note it would be cheaper to run a generator.
Question:	What is the warranty when purchased from Amazon
Answer:	All optima's have a 2 year warranty.
Question:	what is date of manufacture if buying 2 right now
Answer:	Never buy this battery from Amazon. Amazon sent me a worthless battery, does not take it back, and does not refund your money. The Optimum dealers, or the company itself, will not accept the battery because you didn't buy it from the dealer. DO NOT BUY THIS FROM AMAZON. Find a dealer who will give you a warranty, and replace it if they sell you a dud. Learn from my expensive mistake. That's the only advice that really counts. (For me, I bought a great marine battery from Costco, and brought the Optimum battery to a recycler for disposal.)
Question:	how many AH
Answer:	On top of battery AH 66

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.

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.

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

The heart of the VMAX is the unique physical and chemical structure of its plates. The special treatment and manufacturing process they undergo gains them unique reliability, strength and high performance far exceeding those of other Pb-Ca plates used in similar looking products. Using our specially designed Absorbed Glass Matt (AGM) between the VMAX plates, adds to it many physical and electrical advantages that make it superior to the Wet Lead Acid Batteries. This also maximizes the VMAX resistance to shocks and vibrations. Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as “non-spillable and non-hazardous”. A tough Tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAX Tanks are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application.

• 13"*6.8"*8.8h Heavy Duty 12V AGM DEEP CYCLE BATTERY with Float Service Life span of 8 to 10 years.
• Electrolyte Suspension system VMAX tanks utilize an electrolyte suspension system consisting AGM (Absorbed Glass Matt) of a high porosity that totally absorb and contain the electrolyte. No silica gels or any other contaminants are used.
• Heavy Duty Grids: VMAX heavy duty lead tin alloys provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges.
• Maintenance Free Operation: There is no need to check specific gravity of the electrolyte or add water to VMAX tanks during float service life. In fact, there is no provision for this type of maintenance. Battery Cables: https://www.amazon.com/dp/B07NLJBT65?ref=myi_title_dp
