marine-cjohnsonIn today’s world where there are so many products sold with claims of increased reliability and performance it is sometimes hard to find one that actually does. With this said, I am very pleased to say ThermOil not only meets, but exceeds my expectations. It does so by allowing me to spend the extra time previously spent maintaining my batteries on other important items.

As a Professional Guide and Tournament Bass Fisherman my batteries are my lifeline. Without reliable fully functioning battery power I am dead in the water! Whether it’s ripping across the lake at 75 mph or busting 8 foot waves on the way to my fishing hole, my equipment is put to the extremes. When you spend more than 200 days a year on the water you can find yourself in conditions that can be life threatening. Quality, safety and reliability are demanded from any product I use. These requirements are vital keys to my personal success and equally important to my clients. Since I have started using ThermOil in my Trojan Batteries I have been quite surprised at how quickly the batteries recharge. Even after repeated intense cycling during a days fishing, they still seem hold a charge longer. Additionally, because you do not have to add water almost constantly like you would have to without ThermOil, there is a lack of corrosion on the posts, surrounding wiring and other surrounding equipment. In the past this type of excessive corrosion due to battery acid mist had caused wires to short out leaving me dead in the water. With ThermOil, I do not need to worry.

For a product that is inexpensive and provides these great benefits I certainly give ThermOil my highest recommendation.

Thank you ThermOil!

marine-welchTerry,

We have operated houseboats on Lake Powell for many years. Anyone familiar with this area knows how harsh this environment can be and the extremes in temperatures that are possible. Power for all of the equipment and appliances on these houseboats are provided by generator or by large numbers of 6 and 12 volt storage batteries. Batteries are deeply discharged on a daily basis or may remain unused for long periods of time. We have used Thermoil in our 22 batteries since 2002. We, as well as others at our marina, have been amazed at our batteries’ longevity, low water usage, and lack of battery corrosion and fumes that adding Thermoil has produced. Most of our houseboat dock mates have replaced their battery banks at least once and sometimes twice during the lifetime of our original set. We are very pleased with the performance of this product. When the opportunity presents itself we introduce Thermoil and recommend it to others wishing to extend the life of their batteries, decrease corrosion and lower water consumption.

marine-luceI’m an obsessive angler and a fishing guide, on the water from spring through late fall, and that translates into a lot of fishing. Which means a lot of work for my trolling motor batteries. I use Thermoil in those batteries religiously. I am now winding down my fifth season on the same pair of trolling motor batteries that run my 24V system, and we’re talking about coming off the water and hooking up the charger after every fishing trip. When my boat shop winterized my motor last November I had them load test the trolling motor batteries to see what percentage of charge they were still accepting. One-hundred-percent. After four years of fishing and recharging? One-hundred-percent. Absolutely amazing for a guy who, in the bad old days, used to have to replace his deep cycle batteries every year. Five years on the same batteries and who knows, maybe six? I should also mention that I haven’t had to add water to my batteries in over a year. Thermoil gets full credit for keeping me going year after year.

marine-larry-johnsonHello Thermoil,

I have one question for you. How long do these Thermoil 6-volt golf cart batteries last? I have a 16 ft. jon boat with a 50 lb. thrust trolling motor. I fish the Wolf River here in Wisconsin for walleyes every chance I get. I mainly float and jig all the time which requires running the trolling motor off & on all day long. I used to have to buy a new 12-volt deep cycle battery for my trolling motor every other year. I spoke with you back in 1995 and you stated I should get two of your Thermoil 6-volt golf cart batteries and hook them in a series to get 12-volts. You stated back then that they would probably last 3 times longer while providing me with twice the reserve capacity. I had never heard of hooking two 6-volts together and was very skeptical, but decided to give it a try. Wow, were you ever right! I should say some what right. They didn’t last 3 times longer; they are now 12 years old and still going strong – so that is 6 times longer while saving me $$$$$$ hundreds of dollars. I have more power than ever before and can fish more than twice as long before the trolling motor starts to slow down. I have never had any corrosion and only had to add water several times. I am now making plans to take my boat to Canada for a fall fishing trip. My question is how long do these batteries last? I don’t want to replace them since they are still going strong but I do not want them to die up in the Canadian wilderness either and ruin my fishing trip. If they make it to this spring that will be 13 years. Please advise me what to do.

marine-walleyguideI have been guiding and fishing tournaments now for the past 10 years. The tournaments that I have fished include the MWC, Cabela’s, and the PWT. When I first talked with Thermoil Inc.® about batteries three years ago, I was very speculative. Well, I just wanted you to know that everything that they said turned out to be true and then some. I fish for a living so I am basically on the water every day of the year. When I am not guiding, I am fishing tournaments. Most of my fishing involved running my trolling motor for hours on end. I would have to replace batteries every year, sometimes twice a year. This will be my 3rd year now on the same set of Thermoil Batteries. There is no corrosion and I only had to add water once so far. These batteries are still working flawlessly and keep me going all day. Before I endorse a product I have to use it myself to make sure that it performs as stated. Thermoil does everything that it claims. I want to thank your company for the sponsorship this year and I am proud to endorse your product Thermoil. I look forward to many more years of working together with your company. I only wish that I had heard of Thermoil years ago.

marine-worldseafishingNow as everybody in Britain is well aware, the weather has not been the best for boating. This has meant that our testing of this product has been a little belated. However not to be put off by a little wind and rain, Sea-Fishing.com braved the worst to review Thermoil Inc’s Thermoil Battery Additive. Thermoil mainly benefits lead based batteries, but it can be added to any battery, which has caps on it. Thermoil is clever stuff. The oil basically creates a film, which sits on top of the acid/water solution which batteries are made of. This means that the bubbles created when charging a battery break less violently on the surface. This does two jobs, firstly it reduces the amount of water lost from the battery because it reduces the misting effect and so the amount of water you lose through evaporation. The oil also stops explosions within the battery. The use of the oil means that because bubbles have to force their way through the oil in order to break there are fewer gases present and so the explosion factor is reduced greatly. In addition to reducing the explosion and misting factors the oil also prevents corrosion. It is no good adding the oil to a battery which has corrosion, because once corrosion sets in; it can’t be cured and spreads throughout the battery. However if the oil is added to a new battery the corrosion is greatly reduced. This means that with less corrosion your battery will become more efficient. Charging and discharging becomes more effective because as it not has the resistance of corrosion to overcome. The oil can be applied to a multitude of batteries, a list of which is available on the Thermoil Inc website. So is it worth the investment? Yes. An efficient battery is a happy battery and should serve you better and longer than a battery without the Thermoil added. The Thermoil will help reduce any chance of explosion, keeping you safe and also reduce corrosion in the battery keeping it in perfect working order.

marine-midwestoutdoorsThis question is for boat owners who fish a lot: How long does your trolling motor’s deep-cycle battery last? Yeah, mine too. Disgusting, isn’t it, considering how much those suckers cost? How would you like to buy your next battery a little refreshment, sort of a shot and a beer to cheer up a hard worker who’s in for a long tough summer? Over the past four years I’ve become a life-long believer in a little pick-me-up for my batteries that’s very affordable, very effective, and can double or even triple your battery’s average life span.

I fish a lot. Low-balling my estimate, I’d say I’m on the water 120 days a year. Every time I get home from a fishing trip I hook up the charger and recharge the trolling motor battery. Deep-cycle batteries are intended to handle repeated charge and discharge cycles but that’s a lot of charging nonetheless (especially when you consider I come home tired and am not exactly diligent about checking my battery fluid levels each time). A summer has never passed when I haven’t ignored water levels until the plates were eventually exposed. Whatever percentage of plates was exposed, the battery subsequently lost that percentage of recharge ability. There were also a few times over the past 20 years when I was in a situation where I couldn’t recharge after each use, sojourns to the far reaches of northwestern Ontario or extended island camping vacations on the Willow Flowage. For over 20 years the end result of this battery abuse has been the purchase of a new one every spring. That’s both frustrating and expensive.

Then four years ago I happened across a press release about Thermoil batteries, found my interest piqued by what I read, called Terry Fellner, the president of the company, and asked about a zillion questions before I bought one of his batteries. This past November I completed an Unprecedented fourth season with that same battery. The battery I bought from Fellner is a high-quality, heavy-duty marine deep-cycle battery with extra thick plates; one of the batteries Thermoil used to sell before they opted to sell the patented high tech oil itself instead of trying to develop a nationwide network of battery distributors. I’m not sure how many cycles my battery is rated for but it has already been through 300 or more and I fully expect to get at least one more year out of it. If that happens I’ll have used the same trolling motor battery five times longer than any battery I’ve ever used.

Don’t take my word for any of this, be skeptical. Go to the following website: www.thermoilbatteries.com and read anything and everything but especially the Frequently Asked Questions section. For instance, don’t expect to rejuvenate a used battery that already has corroded plates. Realize that you can’t extend a battery’s life indefinitely. Learn why Thermoil now sells the oil instead of batteries, etc. Your new battery will thank you. I strongly urge any boat owner who piles up the frequent-fisherman miles and plans to buy a battery this spring to invest a little pocket change in a bottle of Thermoil. Thermoil currently sells for $12.95 per bottle, which is enough to buy you next trolling motor battery a shot and a beer before it spits on its hands and digs in to work.

Still have the original batteries that came with my 1996 Jayco 5th wheel trailer. Haven’t seen any corrosion and I really don’t remember even having to add water. I am ordering 2 bottle of the oil to be used in my houseboat batteries. What an exceptional product.

Dear Terry,

Just wanted to drop you a line to say my Thermoil Batteries, and I believe there are ten (10) of them now in use on three different vessels, all are operating flawlessly. None has consumed any electrolyte – the tops of the batteries are dry – there is no corrosion. On one of the vessels, the deep cycles are in a very confined space and there in not even any smell of gassing. We intend to replace eight (8) batteries on out 68’ vessel here in the near future, all with Thermoil batteries. We have researched the Interstate™ batteries, the gel batteries, and the Concorde sealed AGM batteries, and dollar for dollar the Thermoil batteries are hard to beat. They are as maintenance free as a gel; they are as gas free as a gel; they are not nearly as susceptible to the shortcomings of a gel with regard to recharging. As far as I am concerned, as well as the individuals now using your batteries under my watchful eye as a marine surveyor and consultant, we are all ecstatic and I only wish the general public could be made more aware of the great properties of the Thermoil Batteries.

Sincerely,

WRL

Dear Thermoil,

I wanted to let you know how your batteries have changed my thinking. I’m a serious tournament fisherman and spend several days a year on the water. Its not unlikely for me to fish 12 and 14 hour days. When I’m not tournament fishing then I’m just fishing for fun. I have had three of your Motor Guide Thermoil batteries in my boat for four years. During those four years I rarely had to add water, never needed to clean corrosion, and I was never stranded with a dead battery. On top of being very low maintenance your batteries have outlasted any other brand I’m tried. Normally I would replace my boats trolling motor batteries every two years. The Motor Guide Thermoil batteries have saved me time by being low maintenance and have saved me money by lasting twice as long as other brands.

Thank you for such a good product and for allowing me more time to do what is really important… FISH!

Hi, I have had varying success with different brands of batteries and need two new ones for my boat to run my electric motor and depth finders. Any recommendations you could provide would be appreciated. I will certainly be adding Thermoil because it seems like the water/acid was almost totally gone after only two trips last year.

Thanks!

Jan Dauve


I have used batteries with the Thermoil treatment in my many boats and I like it .They last longer and I don’t have to check water as often.

Terry,

I would like to thank you for your product. I purchased a 2004 club car precedent golf cart and noticed that the battery life was not at all as expected. Upon further research, the replacement batteries were going to cost me from 800-1200 dollars. I thought I was going to send a fortune getting my cart back running at full potential. A friend at a local cart shop recommended that I do some research on the ThermOil product line. Doing the research and talking with you made me confident that your product would suit my needs. After putting the Battery De-Sulfater into my batteries and patience, the batteries increased their life FROM about 30 minutes TO OVER 2 Hours running constantly. THIS PRODUCT WAS WORTH EVERY PENNY AND SEVERELY IMPRESSED ME. I would honestly implore everyone to delay on buying new batteries and put ThermOil products in their electric carts.

This company will have my business forever.

Thank You!

Just wanted to drop you a line to let you know that these are the best batteries that I have ever owned. Just got the boat out last week and went fishing and trolled most of the day and the batteries are still holding up great. I can’t believe it, this will be the 6th year now and there is still no corrosion and I’ve only added water twice. I have to say that I fish every chance that I get which is about 150 days a year or so and would always have to buy new batteries every other year. For the little extra money that the Thermoil Batteries cost, it sure was worth every penny and was money well spent. I figure that I have already saved about $260.00 because every two years I would have to buy two batteries for my 24-volt trolling motor at around $65.00 each and believe me I think I’ve tried them all over the last 20 years or so. Anyway I just wanted to let you know this and I will recommend your batteries to everyone that I know. I will drop you a line when the batteries finally give out but who knows when that we be. I wish you much success with your business, you have a great product.

As I explained when I first bought this battery, the weakest link in my boat gear has always been the trolling motor battery. Because I have to recharge them so often, standard batteries are always wimped out by the end of a season. Which means buying new battery each spring. This spring I’m entering an unprecedented fourth year with the same 12 volt Thermoil battery. As an outdoor writer and guide I fish from March into November, I’m on the water four to six days a week, and I recharge my battery after each fishing trip. That’s a lot of recharging. The Thermoil battery has suffered the same abuse and neglect as it’s predecessors — low water levels twice, uncharged “”sit”” time longer than a week at one point and constant several-times-a-week recharging for three years — yet like that pink bunny with the drum, it keeps on going.

I know that eventually I’ll have to replace that battery, but I can guarantee that it’s replacement won’t be anything but a battery protected by Thermoil. Thanks again for beefing up my weakest link.
