NOCO GENIUS1: 1A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Little Miracle
Okay, I did NOT expect this little thing to work, but it did and might for you IF you have patience.My Grandfather who was MoAT (Mechanic of All Things) owned back in the day what I thought were REAL chargers, they were so big and heavy they had to be put on wheels and rolled around, they had giant switches that’d illuminate and while I’m probably purely imagining this they were plugged into 220-volt outlets. This thing fits in the palm of my hand, just as pictured, smaller than most mobile phones. “Huh,” I said, “this should be comical.”I hooked it up and, as others have said, figuring this thing out is NOT straight forward, the instruction manual is weak to say the least, the good news is, as I found, there are many intrepid experimenters who, like me, bought it on a whim and did some trial and error which it’d seem 99% of them got the thing to work to their needs, just like me hence, I’m taking the time to write this review. What this lacks in coherent features or instructions it makes up for it in the end by eventually (boy I mean eventually) getting the job done, for that honestly I’m giving it a generous five stars, because it did what I wanted it do against all odds, just like the Phil Collins song. (“Just take a look at my car now, ’cause it’s finally starting here.”)To get the to point, this took TWO WEEKS to charge a completely dead battery in a completely dead system. If it’ll help anyone I own a 2000 Lexus RX300 that is, in fact, drinking age, if I could find a small ute-friendly bar to have a couple with me of which, in terms of trusty old friends, this boring beige over beige has been one of my best now with over 270,000 miles with no reason, per the Lexus dealer, to give up the ghost before 300,000. Toyota quality and then some with only wearables and maintenance needed BTW, the car has only had one issue, eating car batteries every four or so years. Being a cheap bastard and Lexus parts are pricy I’ve chosen battery over a slightly-off generator which brings us to the recent hullabaloo and the need to be the Noco Genius, though it’d prove not straightforward as I hoped.Hooking up the Noco Genius you get a slowly blinking light, like a heartbeat, that will tell you nothing really. Also there’s a force-charge setting where you hold the button (there’s only one button on the whole thing, this thing is basic) it supposedly will force a charge into a battery… this doesn’t work, at all. After some digging it supposedly only does this if a battery is below some arbitrary limit which, my battery was completely dead, kaput, nada, force charge only made the 6V light go on which, apparently, is what others experienced. Point being, don’t hold you breathe.I kept trying to charge the battery but it didn’t budge, didn’t budge, didn’t budge, then I had a thought and said to myself “self, what if I unhook the battery, THEN charge it?” As in, is it because it’s also hooked to my car hence current is going other places? Mind you, this thing is only one (1) amp, that’s very little, if you’re looking for a quick charger or something to charge and jump your car, this ain’t it, have you seen the size of this thing? Ha no, no, but it will trickle, very slowly, a charge into your battery… if it’s not hooked to the car.Listen, some people this may work when the battery is not hooked up and, in fact, I hooked my battery back up AFTER this thing actually worked and then hooked up the Noco to it and it did, in fact, go from red blinking to green, sooo, yeah, that happened. But I’m burying the lede here:The Noco charger worked for me but ONLY after it was hooked to the battery without being connected to the car. Total time to charge the battery not hooked to the car? About 36 hours. Great? Eh, there’s a pandemic, I’m not really going out much so had time on my hands, not to mention my wife’s car.In summation, IF you have even a completely dead battery or run down battery and IF you don’t have to go anywhere in the next two days and IF you’re comfortable unhooking the leads from your car to your battery so that it’ll only be charging the battery itself this Noco Genius is, er, uh, genius! It really works! It works and for the cheap cheap cheap money its worth every penny. If this thing cost even 50% more I’d be taking down stars but this thing cost less than a steak dinner (back when I ate steak) so suffice to say it got my battery charged all the way up, hooked up to my car and after the computer was all “what the… ??? Was I in a coma” my car fired right up and ran, I even drove it around a bit.This would be a good thing to own for just-in-case as its just in case money. If you have any situation close to mine, get this trickle charger, if you need the big guns, well, open up your wallet and say ah. Luckily most of us, probably 99% of us, if your battery is run down, this will do the trick.Best of luck!

Easy to use, great sizing and works great!
I bought 2 0f these and wish I’d bought 3! What a nice little easy to use maintainer. I tried it on all my vehicles, tractors and ATV batteries. Several of these get used regularly but not daily. I was amazed that they needed topped off as much as they did. Red light shows charging, then when they are getting closer to full charge, the green light pulses doing battery optimization, DE sulfating maintenance. Full green means fully charged. Very simple easy to use, just go thru the mode button and select your type of battery. Just a note on big batteries it took several days for the full green light

I Really Like this Item
I will try to be as honest as possible because I depend on other people’s reviews and feel I want to help the best I can: Item arrived just as described. This appears to be a well-made and quality item. Every Winter I must totally disconnect my Riding Mower Battery to keep the Engine clock on the mower from wearing it down. In the spring I must hook the battery back up, cross my fingers and hope the battery has enough charge to fire the engine up. I decided enough is enough and invested into this little gizmo. WOW am I impressed. I got the 1 Amp because I do not need it for charging dead batteries but just to maintain the mower battery over the winter time. I also picked this one for the mower because it plugs in directly. I did not wish to have a smaller cord run across my shop floor all winter while I walk on it. SO, I got a 15′ extension 12/3 Heavy Duty cord to run to the mower. I plugged this item into the cord and hung it on the back of my Zero Turn mower. Then I ran the battery clips to the battery posts. This way I’m walking on a thick heavy duty extension cord all winter, which will be fine. I can even roll my wheelbarrow on it without incident. My mower had been sitting about one month unused when I decided to purchase this item. Once plugged in, it did everything exactly as expected from me watching You-Tube videos and such. I saw it was charging and left it alone for a few hours. I came back and had a solid Green light on meaning it is now just maintaining. I have checked it daily and it’s working great so far. Now I will not need to disconnect my mower battery ever again AND the battery is fully charged when I’m ready to start it up again this spring. I will NOT be using this item during the spring or summer months because I run my mower once or twice per week as a normal. I Recommend. Good Luck.
