Questions & Answers

How should I protect the watch from the elements? Does it have to be waterproof or can I wear it outside?

A weatherproof seal appears to have been applied. Over salt water and only with a roof (no sides), mine hangs in a boat shed. There have been no problems so far. I use this corrosion-fighting product called Corrosion X (available on Amazon) on all my electrical connections on the Years go by before it wears out. The electrical parts of this unit worked well after I sprayed them with WD40. You may find a marine corrosion repellent in a green bottle -- Marine Corrosion X. In comparison to the regular red bottle, this kind is MUCH thicker. Ninety percent of my applications require me to use the red bottle. The green paint can be used on things you may never need to work on, especially if they are I have a brother in law who is a pilot and they use Aviation Corrosion X on their ag and pleasure plane. The store also uses Genius chargers within fully enclosed cabinets mounted on 3 walled hooks. It was the Genius team who introduced me to the site. It usually takes between 24 and 48 hours For a fully discharged 12 volt battery to be recharged, it takes 36 hours. However, she will be able to maintain one just as Wishing you the best of

What is the best way to keep agm Odyssey 31 batteries fully charged, the 10 amp or the 4 amp (genm2)?

As both of them charge the 10 at the same time, it The lower keeps me busy on Monday night, so that I can fish a tourney plug at 11 p.m. I should have a full charge by the morning when I leave for work if I arrive after 700 pm. It is because I don't have a garage that I disconnect when I get home from work, and they are still good even if I don't get I on the water until the following week. It is nice to be able to charge slowly.

What does it mean if there are no lights on when I plug in the charger?

One of several things could be causing the problem. Verify that you are using a good outlet, that it is sending out 110v AC power. The outlet should be filled with something else. You need to make sure your cords are properly connected Last but not least, if those battery output cords have inline fuses, make sure the fuses are intact. After you have verified all that, if you still cannot get any of the charger's lights to come on, it is probably toast! Does the product come with a warranty from Noco? Call them to see if they can provide a repair service. Charger failure could be caused by a failed component.

The product and service were excellent
3/5

I purchased two banks of 12amps for my boat, a 24 foot sport fisherman. For a few months, it worked fine. One morning, when I went to start it, the A look at its charger revealed it had swelled to twice its original size. Moreover, every one of my batteries was dead. My batteries were tested and found to be faulty when I took them in for replacement. Additionally, I now have to pay $250 for 3 batteries. I've contacted the company about a replacement charger. They told me to send a proof of purchase and the charger. It was close to 8 months ago when I did this. The same charger arrived back in the same condition as I sent it out in a different packaging. It's just that I need a new one. A boat sat in the water for the first half of a season with no battery charger, which is not safe and can cause the boat to sink in heavy rains. Currently, there are no reasons to be happy about the service or item. Here's an update On top of that, they offer me a $15 gift card to delete my review instead of a replacement. It's so sad!.

A new batch of batteries has been boiled! In order to maintain my brand new boat batteries while it is in storage, I purchased this unit
3/5

I went to start the motor today, but it would not start. The batteries have all been pulled and all three of the cells are dead. In my last check, the level of each of them was topped off, and the specific gravity of each cell was checked. Next week I'll pick up new batteries for this machine and replace it. Expenditure of money I should not be making.

I have never been able to use this charger
3/5

A battery charger that you can leave aboard your boat would be the best option, but I would check other places. It is my job to be a Electrical Engineer, so I can tell you these chargers are garbage. Three brand new batteries have been on this three bank model for three days without changing states to indicate that the battery is fully charged. For the charger to go from one state to another I had to keep disconnecting and reconnecting the leads. By using my Schumach charger, I was able to confirm that the batteries were fully charged. It happened to me on three other boats I have with deep cycle batteries, so I pulled out my boat and switched them out. If you search other places, you'll find that these things fail.

It's okay as long as your batteries don't get too low
4/5

Since my charger for my two bank batteries died, this was much needed for my three batteries on my boat. I replaced my old charger, which had a 12 amp 2 bank, with a 12 amp 3 bank and it does charge faster than the old one. This is nice because there is no need for different settings for different types of batteries and you can just The plug-and-play design makes it very easy to use. There was only one reason I did not give it a 5 star review - it took 2 days to charge my trolling motor batteries that were almost Perhaps it wouldn't have got so low if I'd had the charger when I needed it, but taking that long to charge 2 size 27 batteries is quite inefficient. It does work, however, and is very.

I highly recommend you read the description before you make a purchase
5/5

The quality that went into making this battery tender is outstanding! I have owned a lot of cheap tenders in the past, and this one is worth every penny. As you can see from my notes, if you're aware of these 2 factors, you won't be surprised when it comes time. A mini jumper and two underwear are on their way to me It's a breeze to swap my batteries in and out with the cable style ends. Click on the link below to see the notes. In the event you do not have available wire in your area, you will need to purchase the wire to fit a replica of the one described just now. A few notes This is *br*br*br*br1. In the case of a dead battery, you will have to jump-start it If you want this tender to work, you first need to charge the battery. The second paragraph. As a result, it is not packaged with a jumper There are cables style connectors, so if you have a battery that has posts, then you will need a connector for it or a mini jumper. You will need a cable attachment (Aligator Clip) that fits your battery holder.

Charge your NOCO Genius phone like a pro with these incredible chargers! NOCO Genius chargers are the best that I have ever used, and I always use them
5/5

They are extremely useful and can be used for a variety of purposes. In my garage and in my vehicles, I use six of them. In order to keep our ATVs charged between uses, we have a two-position charger. This has significantly increased our battery life. My NOCO chargers are charged in all three places for I am consolidating space and maximizing battery life on my summer water toys. I have added one to each of my vehicles to recharge my batteries. In most cases, the devices are inside, but there are a couple under the hoods of the vehicles, so I ran the power cord outside to put them in without opening the hoods. of them is on my truck so I can keep it charged during the winter months. I highly recommend these units as I have never had an issue and they are well built!.

To Charge Your Boat Simultaneously, You Need This Solution
5/5

This is a great site! A marine battery charger is on board! As well as including this on my bass boat, I also added shore power connections to the battery compartment hatch in order to charge all 3 batteries by simply plugging my cord into the connection, rather than using alligator clips and a single battery bank. things are pretty expensive at first but once you get past the initial price, they will save you a lot of time! There are some reviews complaining that the leads aren't long enough to charge three devices. It is designed for use when three batteries are kept in one area, but it is obvious that some people can't read since they can't read.

It was well worth the price
5/5

Every time you use it, you'll be charged fast. I love this product. Three batteries can be charged very quickly on this charger. We usually sit out on the lake with music playing on our two extra batteries while the three batteries are charging. It is just a matter of plugging an extension cord into the extension I mounted in the seat area of the boat which I mounted drilling a 2" hole in the boat. Our experience with it has been flawless, and we have never had any issues. The device is water-proof, and nothing has ever been able to damage it.
