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 Read more

Honestly I thought the battery repair function was gonna suck and not work but MAN WHAT A SAVIOR! Worth the money based off that singular feature alone! I always buy the best batteries on the market for my fleet of vehicles, and yet somehow some way somebody forgets to plug in the maintainer or leaves the headlights on or keeps starting and shutting the car off every 2 minutes for absolutely no purpose other than to hear the exhaust GRRR!! Of course these people end up making my batteries useless after about 3 to 6 months time. I was shelling out hundreds sometimes thousands for new batteries in these vehicles every year. Well, Not anymore! This noco genius 10 took a battery that couldn't hold more than 4 volts, wouldn't charge from the alternator and not only fully charged it in a few hours, it also repaired it in under 12 hours and now that same battery can hold voltage for over a month without dropping below 12.68v under load with the vehicle off. When I tell you this thing has saved me thousands, I mean it. I'm buying more. I wish the units with more power / amperage were cheaper to buy. 10A just isn't enough for many vehicles I have. But I'm not about to shell out upwards of $800 for one 50A charger. Instead I'll buy a couple more of these and try to get my people to take better care of the batteries.... (yeah right) Very compact, Very sturdy, Durable, and Lightweight. The included cord length could and most definitely SHOULD be longer by many feet. Even the extension cable you can buy isn't very generous, Instead I've ran permanent outlets to each bay specifically for these chargers. Read more
