Bought this device to handle a specific battery charging issue-maintain a charge in a motorhome battery set but have found it to be a Go To tool in my commercial truck repair shop. You can;t use it for industrial jump starting but it WILL charge a seriously weaken battery pretty fast. It's big claim to fame is its' ability to recover batteries that have been abused by keeping a low charge rate or permitting them to go completely dead (a genuine battery killer). It works on ALL types of batteries found in the commercial trade and the G26000 series has the power to charge multiple heavy duty batteries at a time, in series OR parallel without fear of damage to the charger OR the batteries. Leave it on all night or over the weekend, or all week. When you come back the batteries are topped of and cannot be overcharged due to the internal protection circuitry. It is easy to use and is fool prof when hooking it up. Hook up wrong and the machine just gives you dumb stares. I was MOST impressed when opening the box and encountering some really high quality connection hardware. The high amp cable attaching clamps are made to last, even after repeated clamping cycles. They are impossible to twist and clamp with great security. The other accessory caballing was well thought out and of equal quality. This stuff was not an afterthought, but a serious design attempt to place high quality and high performance into the hands of the buyer. Cudos to Genius for that extra effort. You can buy a battery charger at Sam's Club for $105 and it will do only two things, charge a flooded cell battery and jump start a dead car. And one of the great things about a Sam's Club battery charger is that after about 4-6 months use, you can look forward to buying another one as yours will be ready for the scrap heap.

I have a golf cart i use extensively through the summer. The past few years, I've brought the cart home and kept the batteries on the standard golf cart battery charger. This year, i wanted to leave my cart and just bring the batteries home. I have 6 Trojan 8-volt batteries. I called the place i purchased the cart from and they told me "no problem. Just buy a 24V charger and charge 3 batteries at a time, then switch it to the other three." I originally purchased the NOCO 7200, but it wasn't powerful enough to charge the batteries. It would try to charge for about a day, never moving off 0% charged, and then give me a error code. So i purchased this 26000 charger. I hooked it up and it worked like magic... it went from 0% to 25% charged with an hour. It then took the entire night to get it to charge to 100% and automatically turn itself off. I unhooked it, attached it to the other set of 3, and by the end of the day, those were fully charged as well. Great buy for the price.

Very pleased so far. Was hesitant about buying due to quite a few lower ratings that I am giving the product but I attribute it to users who may not be as knowledgeable about batteries and charging. I used on on boat batteries, a D8 and two group 31 starting batteries. All were at 2 volts or 0 volts. The jump feature worked well enabling the batteries to get to a voltage high enough for the charge cycle to take begin. Took 2 jumps for the 0 volt D8 to come back to life. It does take longer to charge the batteries such that all lights are lit solid than I would have expected but it must due to the algorithms for maintaining charge. These batteries are on the boat and in the cold in RI so will have to see how well they stay charged. From a customer service standpoint I contacted NOCO 3 times asking questions before and after purchase. One time I got the tech on first try, second time via an email but it took a week to get a reply (with an apology through) and third call I left a voice mail and they called me back within 36 hours. Overall not bad and all techs were knowledgeable and from the States. No 4th world call center people.

excelent

The unit itself works well enough, though it is quite a leap of faith when you hook it up and try the 16 volt desulfation mode for the first time.. The user manual is written very poorly, leaving much to be assumed or guessed/hoped for by the user , for instance it says "5.) when finished, PRESS the MODE button three (3) times to exit the 16v BOOST mode and return the battery charger to STANDBY mode." Now herein begs the question for the first time user, it claims to be fully automatic, if so, why would I have to manually exit this mode? Does this mean that I have to monitor it? When I am charging a 400Ah battery bank that cost me almost 2k, I do not want to have to guess. Does it start at 16 volts and hold it there? does it start somewhere else and work its way up to 16volts (it does or did in my case after watching it for several hours with a volt meter attached .....) Needless to say I was extremely worried the next morning, but it worked out OK in the end. however a slightly better written manual would have totally alleviated these concerns. Something to think about NOCO. I think, that the manual was probably written for customers with a very low level of knowledge of batteries and electricity in general. However most of the customers that are willing to shell out 2-300 dollars for a charger, are probably a little more informed than Joe six pack. Instead of printing a manual with a 109 pages of which only 30 some odd are in English, and contain more cutesy marketing blurbs than actual information, try one with one language (the one for the country you are selling that particular model in), and add things, like the actual target amperage in each of the bulk modes, actual expected voltages and or specific gravity that the charger is looking for prior to changing modes, ie the amperage fo the 4 different bulk stages and then the absorption to float stages. these would be of more interest to me as I could compare this unit apples to apples against my solar chargers, my inverter chargers, and other systems that are in place on my RV.

NOTE: THIS CHARGER IS NOT COMPATIBLE WITH X-CONNECT ACCESSORIES. THIS CHARGER IS ONLY COMPATIBLE WITH (((X-CONNECT HD))) ACCESSORIES. I purchased some accessories and found out the hard way the x-connect socket is too small for this charger. Currently 01/25/2021, I cannot find any x-connect hd accessories for this charger. I love the rugged design. This is not just a transformer and some diodes, this charger takes the characteristics of batteries into account when charging. In my view, no battery charger is "easy to use", but noco could have done better in my opinion. I had drained the battery on my truck by leaving a gps plugged into the 12v outlet. When I connected this charger and plugged it in, the standby light came on and it would not charge. After searching the support website I discovered, when the battery is drained so low, one must first do a "jump charge" to bring the battery back up into the proper voltage range. Then the charger worked as expected. Not exactly intuitive.

I just received a G26000 and the charging seems to be out of wack with the listed profiles. I have tried it on a 3 different batteries and have yet to see a voltage/amp reading that matches the expected profile. First I tried it on 2 AGM 125 Ah solar batteries in parallel. This is the bank I bought the charger to maintain. The bank was at 12.96V after sitting for about 2 weeks without being charged. When I attached the charger, in 12V Cold/AGM mode, it initially identified the bank at 25%. It then started charging at 1.75amps slowly climbing up to 20amps at 15.4v. This charging cycle lasted about 5 minutes. The AGM batteries started to sizzle and the charger stopped producing voltage and current. Over the next 20 seconds, the charge indicator slowly rose from 25% to 100% and indicated the batteries were charged. The batteries completed this cycle at 13.4v. I have never had my AGM batteries sizzle before and seeing the 15.5v concerns me. Having the bank fully charged, I left the charger attached and put it in 13.6v Supply. The charger kicked on and I monitored Volts and current for about 5 minutes. In this mode the charger actually lowered the bank voltage from 13.4v to 12.99-13.1 and produced 0.5amps. The amps did not surprise me on a fully charged bank, but never rising above 13.1 vlots. I removed the charger and connected it to an 85ah flooded battery that was heavily sulfated and sitting at 11V. I put the charger in the 12V Normal mode and started the cycle. The charger began the cycle at 12.85V and 1.75 amps. Over the next 5 minutes it slowly increased to 15.5V at 13amps before spiking at 20 amps and shutting down. The charger was reading 25% when it stopped supplying voltage/current and I watched as the battery voltage started decreasing rapidly. While the battery voltage was decreasing, the charger began counting up from 25% to 50% all the way to 100%. Just after displaying 100% the battery voltage had dropped to 12.2V and the process started over, each time lasting no more than 5 minutes. After a couple cycles, repeating as described, I placed the charger in supply mode. The voltage bounced between 12.4 and 12.9 while supplying 2.5 amps. The voltage never went above 13V. I hit the battery with the full 5 minute “jump Charge” and that supplied between 14-16amps at 13.2V. After completing the cycle, I placed the charger in “repair mode”. The battery was reading 12.8v and dropping when the repair mode started. I watched as the charger produced 1.75amp and the battery volts continued dropping all the way down to 12.2v. It would then jump between 12.7V and 12.2V. I walked away and came back a few hours later to find the charger repeating the “12V Normal” Mode I described in the paragraph above. With all that said, I have yet to see a charging profile match what is listed in the User Guide. Charging voltage is way too high for my AGM and flooded batteries at 20 amps. Voltage is way too low for the repair mode. Voltage in the 13.6V supply mode is well below what is expected. I hope this unit is defective because I have no confidence it will not destroy my AGM bank. NOCO told me I could send it to them for testing, but I doubt there is a problem with the unit. I think this unit would work fine charging car batteries, but not my deep cycle solar. The repair mode probably works as good as any other battery charger with a “Repair Mode”. I went with a Victron that does not

Maybe a little over-priced if I only need to charge a regular 12V car battery or two, but that being said, this is a wonder and very safe and solid design. I have used it on several power sources and charged several batteries (of very different condition and ages) and I am actually glad I overkilled it by buying this one instead of one of the cheaper models (I'm sure those other ones in their product line are excellent in their class as well). I could very well find myself needing to loan out this to a fellow camper, or even a neighbor at home, and it will work. The special "quick charge" mode it has will let you turn a dead battery into something that will start the car, in five minutes. Wow. My recommendation: if you need the extra features (and/or the higher current) this model provides, I give a strong YES recommendation. One or two steps down from this one, in my opinion, would also be an excellent choice if they better suit your needs. I bought the G26000, but something like their G7200 at half the price on Amazon, will get you these neat features but with a longer charge time.

Noco Genius 2600 Noco genius 26000 was well packaged, very strong, reliable cables and the delivery was very fast (arrived before specified time). Baptist distribution staffs, seller from who I bought were very friendly. I made exhaustive search and research before I decided to buy. What I wanted was a reliable battery charger and maintainer/repairer and this product fits that criteria. It is like all in one, works for 12V, 16V and 24V batteries. I only used to charge and repair, 12V battery of my Nissan Murano whose battery was dead when it arrived and my other small car batteries. Both batteries were restored back to their original new state. As winter is not yet around, I did not use to boost battery. I have no regret for buying it as it saved me from paying close to 500 dollars for two new batteries. A word of caution: When you first connect it to AC power, it gives orange light on the on/off button and stays there. When you try to use mode button, it alternates between supply mode and power button only. This is explained in the manual but hard to figure out. I bought one and returned back thinking it was defective, but it was not. I contacted support centre and they tried to explain it to me. For it to sense your car battery, once connected, you have to jump start your battery for a cycle of 5 minutes, and that will raise(boost) your battery voltage and noco will be able to sense it. If not done with on jump start cycle, repeat second one after few minutes and that will make noco sense your battery. Definitely, it is not defective but how it is made. After that process every time you connect it sense the battery quick and you can switch between mode options. Good side: 1. Quick delivery 2. Well built and strong reliable cables 3. No need to worry about reverse polarity 4. No need to worry about over charging 5. Very compact to put anywhere in engine compartment with ease 6. As it remembers where it has stopped, there is no need to worry about lose of power or disruption in the connection. 7. Can be left connected permanently for care and maintenance without any fear of overcharging. Down side: 1. It is expensive 2. Cannot be used without AC power 3. Has limited or no accessories compared to earlier noco products 4. The cables are short and need to rely on extension cables which affects charging time if not of same AWG with noco’s cable 5. There is no way of using available accessories interchangeably between products of noco. My suggestion: Please make available, accessories compatible with this product. In the future, think of making available a product like this which can be turned on and used where there is no AC power source. Portable chargers are needed where there is no AC power source and this one does not serve that purpose. All in all: Having looked at other products and comparing with them, I consider this product to be superior. This product deserves 5 stars. Very good and reliable product and I will definitely recommend it to potential customers. I am not sure how long it survives but for now I am completely satisfied with my purchase.

Excellent for charging batteries. I bought this for the large AGM trunk battery in my Mercedes. I have a smaller trickle charger rated at 5 amps, which was unable to charge the large battery. The G26000 is rated at 26 amps for charging an AGM battery, so caution is necessary to unhook the cars terminals before charging. The clamps supplied can be removed from the charging harness and connected directly to the battery terminals. The harness has a quick disconnect to be able to connect/disconnect the charger when needed. Review the Genius website for correct accessories, as I bought a harness extension on Amazon Canada which was not compatible, and I had to return it. The heavy wire charging harness with clamps supplied is rated for 40 Amps and require special heavy wire harnesses. Check the Genius website for correct accessory numbers to order from Amazon if needed, as some of the accessories for the charger on Amazon are not listed correctly.

I bought this charger for my RV battery bank. It is a great charger with lots of features. It was missing a cord and after calling Noco the sent me a new one. Only problem was that they sent me the wrong cord, then wouldn't respond to my emails any longer. I gave up and jury rigged something.

Excellent! I own both a 7200 and a 26000. They work as advertised. They both are picky about the setting, though. I.e. charging a cold battery, one has to select 'AGM/cold" or it won't do. The 26000 is mounted as an on board charger in an RV to replace the original converter. Works like a charm! Under load (appliance running while charging) it becomes a bit noisy. But not as loud as the OEM converter used to be. Charges my 400 Ah AGM battery bank for almost 6 years now. Batteries are still fine. Charger still works. Plugged in whenever we are home (200+ days a year).

Seems to be a good charger. Cables are not designed for cold weather. After 15 minutes outside at -35 celsius I noticed the insulation on the wires split and bare wires. It's a fire hazzard, cables needs to be improved to a more flexible material.
