    • Brought a totally dead battery back to life, still holding weeks later
Size: 10A
My son’s Mazda sat in the garage all winter with a stone-dead battery—interior lights wouldn’t even flicker. I hooked up the NOCO Genius1 smart charger/maintainer and let it do its thing. The progress LEDs made it easy to see which stage it was in, and after about 24 hours the charger showed green. Two starts later the car fired right up, and three weeks on the battery is still cranking strong without ever reconnecting the charger. Setup couldn’t be simpler: clamp on, plug in, and forget it. The unit runs cool and the spark-proof design is reassuring. The only tiny nitpick is that the alligator-clip leads are on the short side if your outlet’s far from the engine bay, but an extension cord solves that. If you need to revive and then maintain a battery that’s been sitting for months, this little charger works exactly as advertised. Highly recommended. ... show more

    • Purchase Noco Genius 2, same features, different charge times
Size: 10A
Personally, I underestimated the utility of the Noco chargers! Commercial grade quality in a small form factor. Very robust and easy to use. Comes with a mountable strap to make it much easier to store. Fast charging, this is where the differences exist in the modes, and after hours of research I found the 10 perfect for me. Make sure the model you choose has the features you want and the main variables is the charging speed. The Noco Genius 10 will indicate if your battery is bad, my M18 Milwaukee batteries that wouldn't charge from charger were brought back to life, and the trickle charging feature brings much more value than you would imagine. To be completely honest.. I recommend the Noco Genius 2 as it has all of the same features yet it charges much slower. ... show more

    • Great product!
Size: 10A
Had a 1 year old optima red top that died over the winter. Come spring it wouldn't stay charged. After hooking this to it and letting it try to charge it over night in showed the error message won't hold a charge. I then put it in repair mode and let it go for a few hours. It fixed the battery! It's easy to use. Connects well. Small and compact. Quiet. Great value for the price! ... show more

    • Saved me from buying a new battery!
Size: 10A

EDIT 2/26/24: I am now the blocks "AAA". Been helping people start their cars when jump starts with cables have not worked. Definitely handy to get other people out of an otherwise expensive pinch. I have a car battery that I purchased around 2016 (date of review 1/3/24). The car itself does not get driven much, at most 2-3 times a week no longer than 15 minutes one way. Throughout the years I've drained it by leaving the car lights on. Its always required a jump start after that to get going again. Recently I've been an idiot and been leaving my lights on more frequently. Eventually it required me to jump start everytime I wanted to turn on the car. It was becoming a hassle and I was about to call it quits and purchase a new battery until I came across Project Farm's review on battery chargers. This was at the top of the list so I figured to give it a shot. I was not disappointed! I charged it for 4 days straight, put it in my car, and it started right up. Not surprised considering it was just charged but the real test laid ahead. I was going to be out of town for two weeks and leave the car sitting. I came back two weeks later and the car started up, no hesitation whatsoever, as if it was a different battery! The NOCO Genius 10 saved me about $150-200 at least in a brand new battery. On top of that, I can now use it for other batteries in the event of any similar issues. The instructions on the other hand are a bit confusing and had to rely on YouTube comments to piece it together. For those who are confused at what to do, I did not do a 12V repair (function which this unit has) as it requires the battery to be completely charged first. All I did was charge it straight for 4 days uninterrupted. When first put on battery to the charger it will be in standby mode. You push (or hold depending on what you need) the MODE button to select your desired option. I was charging a lead acid battery so I selected 12V. The meter at the top slowly advanceD from each of the four bars until the final bar was pulsing green which indicates its charging to full (over 80% I believe). The green charging light continued to slowly pulse even on the 4th day but I took a gamble and disconnected it from the battery. For the battery to be 100% charged, the green light should stay solid. That means my battery worked 2 weeks later after sitting and it wasn't even at 100%. The unit can also force a charge on batteries that are extremely under voltage. Thats a separate setting that I haven't had to use yet. It can also charge AGM and Lithium but I believe the 12V repair function is only for lead acid. Unfortunately I had to go through 3 separate orders because the first two were from Amazon Warehouse and I encountered issues with both, consecutively. I ended up getting frustrated and just purchased a brand new charger. Pros: Solid build quality Excellent cable connections with weather covers Compatible with a wide variety of batteries Repair and Force charge batteries Cons: Poor instructions Charge is slow BUT I think thats how these chargers work TL;DR Try this first before rushing to get a new battery it is a good investment that can save you a lot of money ... show more

    • 3 different batteries
Size: 10A
I bought this charger specifically for its repair feature and after disconnecting three batteries and thoroughly cleaning the battery post on each, I charged all three batteries, each over 4 years old with each one taking a full charge. I didnt know exactly how the repair function worked and got confused when the red light blinked red, so I had to look up a manual online. One star deduction for no manual provided with the unit. Will update for repair mode ability later now that I know its supposed to blink while in repair mode. ... show more
