NOCO GENIUS5: 5A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Really impressed with this charger. It’s super easy to use—just hook it up and it pretty much does everything on its own. I like that it works with both 6V and 12V batteries and even different types like AGM and lithium, so it’s pretty versatile. It’s also compact but still powerful, and I’ve used it to bring a weak battery back to life without any issues. The automatic maintenance mode is a nice touch too since you can leave it connected without worrying about overcharging . Overall, solid build, reliable performance, and great for keeping your car or motorcycle battery in good shape.

Works great, easy to use and use it mainly to bring my car battery back to full strength as I don't use it that often. I like the mounting bracket. Mounted it on my wall, but I did add a spacer underneath it because the charger gets pretty warm/somewhat hot, thus allowing air flow all around it. The small size & weight is great. The alligator clips are very good and adhere to the battery very well. Its obviously slower that my large 10 amp charger as should be expected, so if your looking for faster recoveries and less need for a trickle charger, get the 10 amp version. I am leaning into getting one to replace my old 10 amp charger.

11/17/2022: Saved me from my very tired self, once again... totally dead battery in my car after leaving the trunk open slightly for a week... hooked this up after giving it a cursory jump with the TackLife T8 and left it to do it's thing. My battery is now in maintenance mode. What a wonderful helper. 4/29/2021: Every time I start my mower I am in awe all over again. The battery performs better than it did last year and the year before. My mower starts quickly now without hesitation and I am so thankful. For someone else, this may not be your solution, but for me, a senior on her own, this was far easier than replacing the battery, and now I have it to use for my auto battery that doesn't get that much use. 4/20/2021: Took a bit of work to repair the damage to my lawn tractor battery that I caused, but I'll be darned, it worked! Ran it through a charge cycle that didn't seem to do anything and I wasn't optimistic, but I was persistent. Did another charge cycle that it completed, I think, and then the next day ran the repair. The following day I did yet another charge cycle and tried to start it up and I'll be darned, it worked! All the damage I did, my negligence, this great gadget fixed. Nothing else I own, Battery Tender, Jump n Carry, etc. would do anything. I bought a different jump starter, TackLife T8 Pro, that actually got it started but all that did was show me how truly dead the battery was. As soon as I turned off my mower it wouldn't start again. Noco Genius5, and the steps I took, solved that. It wasn't fun since I'm disabled, and it was time consuming, but the end result is what I wanted and needed. Very satisfied customer. A note about the manual... boy does it need to be fixed. Nothing matched what went on at any stage of my repair and charging. My persistence and a lot of finger crossing made up for really horrible instructions. 4/11/2021: My lawn tractor battery is in a disgraceful state and it's my fault, combined with continual rain since October that prevented me, due to poor health, from taking the steps necessary for year-end maintenance. Big surprise, totally dead battery with 0 volts that nothing I had on hand could resurrect. Tried jumping it with my Jump n' Carry and it didn't. Next tried jumping with the TackLife T8 Pro and, boom, it started. Wouldn't restart and maintain the start so I grabbed the NOCO Genius5 that I bought at the same time as the TackLife. Yesterday I was very discouraged because lights on the Genius5 didn't appear to be working per the manual. Tried it just now and it's responding, led-wise, as it should and appears to be charging. Truth told, totally my fault, I should be buying a new battery, but, physically, I can't do what it takes to do that. Single senior here and my son is on the other side of the country under no-travel orders, so my life is what it is. I must get by whatever means. Really hoping this works. If I can get it charged again I'll ride this battery as long as I can and then get a new one.

Perfect for what I needed. Very easy to use and works well. It does take some time depending on your battery but worth the price.

The NOCO GENIUS5 does exactly what it’s supposed to do. It charges my older vehicle’s battery quickly and efficiently. I noticed it works faster and more reliably than the cheaper charger I own. It’s is more compact, well-built, and feels like a quality product that’s designed to last. However, I do wish it came with an instruction guide explaining its functions and indicators. As someone who isn’t particularly knowledgeable about cars, having clear instructions would have made things easier. My cheaper charger actually came with a very helpful guide, so I was a bit surprised that this one didn’t. I ended up having to look online to make sure I was using it correctly and safely. Another thing I notice is that the button is not as intuitive. There's a delay when pressing the button. That said, once I understood how it worked and managed my patience, it performed flawlessly. I just wish the user guidance matched the quality of the device itself.

Sensacional, equipamento de fácil utilização e tecnologia de primeiro mundo.

البائع محترم وخدوم صارت مشكله في الشحن وحله مبشاره وخدمن والشاحن مايحتاج تقييم معروف وجربته على هارلي خليته مشبوك ايام والبطارية فل ولا يحتمي ولا شي يجي شاحن ومعه وصلة مقابض بطاريه نفس الاشتراك العادي ورأس الشاحن ثنائي أمريكي لكن عادي قصيت الراس وحطيت ثلاثي ويشتغل معي تمام

I've had this item for 2 years now. And I have to say it is one of the best purchases I've made. Background: I have a older car, that's kept outside here in toronto, The winter's here can be pretty bad. My car battery is not the greatest, and I found my battery was always draining. Constantly needed a jump. I looked at the big suitcase backpack looking ones, that CAA uses, then I saw this tiny noco. I'm glad I took the risk, it's paid for itself many times. Pros: it works. It's boosted my car, when the battery was completely dead. -The safety feature, meaning the electrics won't flow, if it's on the wrong positive or negative, was nice for those times when I was in a rush not paying attention -my model had a boost mode, so when I would activate it, it would force start my battery. -very quick. I always feel a little less than human, with people judging me when I have to jumpstart my car, I'm sure nobody cares, but I still feel a bit inadequate. This jump starts my car almost immediately. -this thing is tiny, I keep it in my glove box, it does what those huge jumper boxes that the professionals have, but since technology is so fantastic, they're able to make it so small but so powerful -I'm really impressed with the charge, I charged it once and it lasted over a year, with monthly use. I did recharge it just to be safe at the end of the first year. But I probably could have left it and it would have worked fine, there is a battery indicator as well. Cons: When I pull it out to help strangers restart their car, they look at me a little bit crazy thinking this little item can help. Then they ask me, where they can get one minutes later :) Recommendation: If you're someone who needs to jumpstart their car regularly, this thing is a lifesaver. Not only am I able to jumpstart my car when I need it fast and safely, I was able to help other strangers, simply because there wasn't a lot to hook up. It's a small unit and putting it on someone else's car, and jumping it takes a few minutes. I would 100% buy it again.

Don’t have experience with battery tenders/chargers, this is my first. But I can say very well built compact size. Intuitive setup. Using it to maintain my jeep wrangler AGM 70AH battery as I travel a lot don’t drive the car that much. Update: It has been amazing after few overnight charges the battery recuperated and seems to be back to its full swing. Starting the car now is seamless.

Para empezar el excelente calidad y acabados al igual que su funcionamiento muy buena terminación del producto
