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

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.

Great compromise between price and usability. A full charge on a depleted battery may take 24 hrs or so but the lower rating allows me to use it with a 100 ft heavy gauge extension chord without worries. I would not want a smaller unit and a larger draw unit would make me worry about using an extension chord. Great and reliable unit.

I've used Schumacher SP1296 trickle chargers for many years now, on multiple vehicles and pieces of equipment. Recently I switched all of them to the NOCO GENIUS5 and it's better in every way! On all of the Schumacher chargers I've had, (and that's been a LOT of them) the cord has eventually frayed and broken where it exits the charging unit. On the NOCO, the cord has a rubber reinforcement where it exits the unit, extending the life of the cord. I've included photos of the NOCO (black) and the Schumacher (red) for reference. The Schumacher chargers I've had were dependable and functioned well, but their cord design was a major design flaw for me. Multiple times, It forced me to replace the units before I should have needed to buy new ones. The NOCO is slightly heavier and more compact in size than the Schumacher. The control has more functions and is easy to use. The NOCO display is aesthetically more pleasing and easier to read than the Schumacher. The NOCO also has an on/off switch which is nice. I always use the eyelets to connect to the battery. The charger connection to the eyelet cord has a click type plug to lock it in place, unlike the Schumacher which just presses together. Should you want to use the battery clips, the NOCO clips are bigger and stronger than those on the Schumacher. The only negative aspect of the NOCO that I found was that, according to their user manual, "This product is designed to work in ambient temperatures between -4°F and 104°F". This has not been a problem for me, even when used outside in northern Vermont. It does get below zero here, but typically not for extended periods of time. As long as the charger is kept on the battery, and it's always fully charged, that temperature limitation hasn't been an issue for me. Overall, the NOCO GENIUS5 appears to be a higher quality and better built charger than the Schumacher SP1296. I am very satisfied with their product, and I highly recommend it.

Great product!! Provides reliable battery charging and long-term battery life maintenance, effectively restoring even deeply discharged batteries to like-new condition. This product has worked flawlessly on my vehicle countless times, and I confidently recommend it to anyone looking for a dependable solution of this kind.

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.

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.

Excelente producto, no me esperé a la luz verde. Llevaba 3 horas en luz roja, intenté encender el carro y encendió. Reocmendado

It manage to fully charge up a almost dead battery with less than 25% power in less than an hour. And took another 4 hours under the repair mode. Now bike could start without any issue. Only wish is to have a voltage reading and longer cable from power plug to charger.
