NOCO GENIUS10, 10-Amp Fully-Automatic Smart Charger, 6V and 12V Portable Battery Charger, Battery Maintainer, Trickle Charger, and Battery Desulfator with Temperature Compensation

Muito bom!

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

I was hesitant to buy one of these because of the reviews about fires. Don't pay attention to those reviews. This little trickle charger keeps your car battery at full and in brand new condition. I read somewhere online that if you put a brand new AGM battery in your car like I did and keep this NOCO Genius10 hooked up, the battery can theoretically last up to 10 years because the NOCO will continuously keep it charged and repaired. It seems that my battery was not the problem with my car as the starter relay on the clutch needed replacing so now my car starts again. But I put in a new AGM battery anyways and won't have to worry about replacing it for another 7-10 years as long as I keep the NOCO attached when not driving the car for long periods of time. As for the NOCO functionality itself it has a couple buttons, one to choose what kind of battery you are using, regular 12V, AGM, or Lithium Ion. The other button I believe is for what kind of charge you want(trickle, decharge, repair) but since I have a brand new battery I simply keep it on trickle charge. The cord length is not very long so in order for my NOCO to reach my car battery and the wall socket in my garage I used a decent gauge extension cord. The instructions say not to use an extension cord but there is no other way since my wall outlet in my garage is too far away from the car battery. I keep a smoke detector next to the NOCO and battery just to be safe. I got the NOCO on sale during Prime Day so it is definitely a good value for the money. So far so good.

Brilliant bit of kit. Essential for my ancient Range Rover.

42 years as a mechanic and I have to say I’ve used all kinds of chargers in my life, and the Noco genius is absolutely the top tier of all. set it and forget it. The smart feature of the charger does it all for you. Today’s batteries are quite sensitive to voltage whether it’s a lead acid or an AGM battery too high voltage or too low of voltage output from a charger you don’t realize it, but it will damage the batteries as it charges. AGM‘s are especially sensitive to this. When charging the Noco automatically adjust voltage output and the amperage output as the battery begins to top off preventing damage and allowing the battery to top off fully at its maximum capacity, which is very important on lead acid batteries. This is where cheap to mid range battery chargers don’t work properly. They often continue to flow even when the battery is topped off at quite a high voltage damaging the battery. This charger also incorporates a desolfation mode that can bring most discharge batteries back to life it also incorporates a forced charged mode that will allow it to charge a battery that is down to one volt which most other brands of chargers will not do smart charger or not. These chargers are very well-made. The plastic is not cheap and is very strong. It has good weight to it. The power cable leads our 16 gauge so they are quite thick. The clamps are copper that is plastic covered, but are extremely solid and durable I’ve been using them for years and have never had an issue. The ambient temperature sensors on these chargers are also another strong point as they actually work properly, allowing a battery that’s in a vehicle in cold weather conditions to top off faster and better and then it will keep it there ensuring a strong start to next morning. For those that want the very best charger that will outperform anything else in its category look no further this is the one along with the three-year warranty that backs it up if something should go wrong. I highly recommend this product. You will not be disappointed so spend the extra money and get the best. You’ll have it for 20 + years
