NOCO GENIUS10: 10A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

The NOCO GENIUS 10 is hands-down one of the best battery chargers I’ve owned. It’s compact but seriously powerful, and the 10A charge brings batteries back to life much faster than my old charger. I’ve used it on both 6V and 12V batteries, and it automatically detects and charges exactly as it should no guesswork at all. I especially love the smart maintenance and trickle mode. Once the battery is charged, it switches automatically to maintain it, so I can leave it connected without worrying about overcharging. The display is clear, setup is simple, and the build quality feels solid and durable. Whether you’re maintaining a car, motorcycle, boat, or lawn equipment, this charger just works. Reliable, efficient, and absolutely worth the money. Highly recommend!

So far so good. I purchased the genius 10 in hopes to save some of my batteries around the house and save a little bit of money in the long run. I have everything from cars trucks, RVs, dirt bikes, generators, and everything in between. I use this specifically on my generator, which uses a 12V sealed lead acid battery. I had the generator sitting for a few months in the storage container where it went through some hot and cold Cycles needless to say my lack of maintenance the battery was dead and would not turn over the generator. The generator is a 9000 W champion. I took the battery out and I did not measure the voltage prior to, but I put it on another brand “smart charger”. That brand rhymes with “shoemaker”. That charger ran for a little bit, but then aborted the charging cycle because it said it was bad. I then put that battery on an old-school charger not a smart one one that’ll just run no matter what and left it on for a few hours and then reinstalled the battery again it would not turn the generator over. I pulled the battery out and it measured 11.5 V and I hooked it up to Topdon battery analyzer, and it said the battery was bad. I purchased the Noco genius 10 not just because I wanted to try it on this but because I know all around it seems to be a good charger. As the Noko instructions said, I hooked up the battery and ran it through a normal charging cycle prior to using the repair mode. The normal charging cycle only ran for about 10 minutes before it said it was fully complete. I hooked up my battery analyzer again and again it said it was bad. I then ran the 12 V repair mode on the Noco and it ran for about four hours. After the repair mode was complete I hooked it up to the battery analyzer again and it still said it was bad, but I wanted to give it a shot in the generator. Oh, and I forgot after the repair mode the voltage on the battery red 12.6 V and it held 12.6 V overnight so that was a positive sign. I put the battery in the generator and it started flawlessly. So I spent $99 on the Noco charger and saved myself $40-$45 from buying another battery for my generator so it seems to already be paying for itself.

2 years ago, I bought the NOCO GENIUS 5. I liked it and used it often on my 2013 Ford Escape. However, recently I let my battery dropped too low for the Genius 5 to power it up. The Ford Escape - if the battery drops too low for a period of time, then the fuel pump needs to be powered up too. The "5" just wasn't strong enough for my Escape. So, I bought the 10! It was able to get my battery charged (and it made the fuel pump happy too) and did so quicker than anticipated. I've learned that I need to keep the Genius connected all allow the maintenance mode to keep my battery ready to go. I also learned that the 2013 Ford Escape has a "dedicated jump start negative post" so that it's easier to hook up the black charge. The 2013 Escape battery is partly under the dash and the negative battery terminal is very hard to reach. I am not a car expert, quite the opposite. And I can easily hook up the Genius Chargers —they are really a smart Charger! Once the Red is connected and the black clip is on the negative post, I plug in the charger. The charger automatically reads my battery and sets the charger. If the battery is too far gone, there is a symbol that will light. As the battery charges the lights will change until you see the solid green light letting you know it's been fully charged. You can leave it plugged in the maintenance mode or unplug it. It will never over charge the battery as it has built in safety features! I highly recommend the Genius Chargers, especially if you have vehicles that you don't drive often.

Even I got issue with the item, they sent a new one to. Thanks!

I wasn’t expecting to become that person who gets excited about a battery charger, but here we are. I bought the NOCO GENIUS10 after my car battery kept dying during cold mornings, and it’s been a total game-changer. Setup was super easy — plug it in, connect the clamps, and the charger does the rest. I love that it’s fully automatic and smart enough to figure out whether I’m charging a 6V or 12V battery without me fiddling with settings. The safety features are reassuring too — no sparks, reverse polarity protection, and it even compensates for temperature, which is perfect given how hot it gets where I live. What really impressed me is the battery desulfation mode. I had an old battery that was barely holding charge, and this charger managed to revive it enough to get me through a few more months. If you want something reliable and worry-free to keep your car battery healthy, this NOCO Genius charger is worth every penny.

excelente, un poco confuso de usar al principio, pero una vez entendido el manual, es muy sencillo todo lo demás. Robusto y poderoso, se calienta pero eso es normal en este tipo de dispositivos de potencia Después de haber pasado tristezas con cargadores baratos, aprendí que invertir más en una buena herramienta como este noco Genius10 es el mejor acierto y facilita mucho el trabajo 💪🏻
