Que buen producto carga la batería la recupera y luego la mantiene…

El cargador es el Noco Genius pero el enchufe a la red no es para España o falta en el paquete...a la espera que os comuniquéis y lo arregléis bien con un adaptador o con otro....

I've used a lot of battery chargers and maintainers over the years, and after going through at least four different brands that failed to live up to their promises, I finally bought the NOCO GENIUS5. I only wish I had done it sooner. NOCO is a trusted brand for a reason. The GENIUS5 is well-built, easy to use, and works exactly as advertised. Whether charging, maintaining, or bringing a weak battery back to life, it consistently delivers reliable results. The smart charging features take the guesswork out of battery maintenance, and I appreciate knowing my batteries are being charged safely and efficiently. What really stands out is the quality. Unlike the other chargers I've owned, this one inspires confidence right out of the box. It's clear that NOCO put thought into the design and performance of this unit. Yes, it costs a little more than some competing brands, but in my experience, it's absolutely worth the extra money. I've wasted enough on cheaper chargers that didn't perform as claimed. The NOCO GENIUS5 does exactly what it says it will do, and it does it well. If you're tired of disappointing battery chargers, do yourself a favor and get the NOCO. Highly recommended! ⭐⭐⭐⭐⭐

I bought the Genius5 after neglecting a relatively new battery in my motorcycle. Due to weather and travel, I often have long gaps between rides. Unfortunately, one of these gaps was long enough to damage the battery. I didn’t realize that batteries need a minimal charge to avoid sulfation, and mine had become severely discharged. Although my NOCO GB40 starter worked fine, the battery wasn’t holding a charge even after a day of riding. Instead of immediately replacing the battery, I decided to try saving it with the Genius5. After charging the battery with the Genius5, I tested it with a battery analyzer, which reported it as damaged. I then ran the desulfation process, and afterward, the analyzer showed the battery was in good condition. I repeated the tests several days later to be sure, and the battery still appeared to be in good health. Now, I keep the Genius5 connected to my motorcycle whenever I’m not riding for more than a week, and I haven’t had any battery issues since. I still carry the GB40 in my panniers, just in case, but I haven’t needed to use it lately. Some notes on the desulfation process: The desulfation process seems to send voltage peaks, and you may hear some bubbling inside the battery. This happened to me, and from what I’ve read, it’s normal as long as there’s not too much bubbling and no vapors, heating, or swelling of the battery. The entire process takes a while, so it’s unrealistic to monitor it the whole time. However, I recommend watching it for the first 20 minutes to ensure the battery noises aren’t increasing. After that, you can leave it running while staying nearby, just in case something goes wrong. A final note on this process: because of the voltage peaks, I didn’t run it with the battery connected to the motorcycle to avoid any potential damage to the circuits. For regular maintenance charging, I do keep the battery connected. The Genius5 is designed to work with standard batteries, gel, and even lithium ones. The one I used was a Gel Yuasa, and I’m pleased with the results. I also purchased the NOCO cables (GC002 X-Connect M6) to make it easier to connect the charger without removing the seat. The cables were a bit expensive but seem well-constructed and are quite convenient. Final thoughts: If you have a vehicle that sits unused for extended periods, and this happens frequently, then this charger is ideal for you. However, if you only need it once a year or less, it might be easier and cheaper to disconnect the battery from the vehicle while you’re away to prevent discharging. For my use case, the Genius5 has been worth it, and I’d definitely buy it again.
