    • 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

    • Excellent, compact battery charger for automotive or marine batteries!
Size: 10A
Very nice, compact charger to restore or recharge an automotive size battery. I came back from a trip to find my car completely dead and all I had was an old 1.5A charger. I heard good things about this Genius charger and ordered. I charged my battery up for the most part of a day and it worked great! The clips are of excellent quality and can be disconnected for alternative components like a ferrule-based setup. The Charger is also small - it's perhaps 4X the size of a modern cell phone in terms of thickness and maybe 1/4 again as long. There are 4 lights indicating a charge level - the level it's working on "pulses" slowly until it's done and then it's solid and the next level pulses. Easy to understand. Great charger with quality components - definitely recommended! ... show more

    • Awesome Genius 10 car battery charger
Size: 10A
NOCO makes awesome products! The Genius 10 battery tender is great at charging up a car battery. Charging my work car battery once a week has prevented the battery from dying. Before buying this charger my battery would die at least once a week. My work car has an always on GPS tracker that drains the battery. I also have a NOCO jumper that I was using constantly. Now I can charge the battery and avoid it from dying. Easy to use, just plug it into the wall and hook up the charger to the car battery. ... show more

    • Saved me from buying a new battery!
Size: 10A
Review Image by Matt K Matt K
Review Image by Matt K Matt K
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

    • NOCO charger works well!
Size: 10A
My 2022 Chrysler Pacifica battery was dead when we returned from vacation. We tried jumping it to get it started, but that didn't work as the battery was completely dead. This NOCO charger worked well and completely charged the battery. It took about 24 hours. That was worth 5 stars. A couple of days later I tried to charge another car that had been sitting for the same amount of time. Its battery was still good, but I wanted to fully charge it. Unfortunately, the NOCO charger kept giving an error that it was overheated and would not work. I cleared the error but it still would not work. In all fairness, the outside temperature was about 95 degrees, which likely contributed to the problem. This review should be 4 1/2 stars. ... show more
