My favorite chargers
I love these chargers. I farm and have a large number of engines/batteries to maintain year round. Some engines are only used for a short part of the year so I keep trickle chargers on the batteries, sometimes nearly year round. Because of that I own many trickle chargers and have tried several brands. My favorite for years were Battery Tenders (and I still have several) but I think I like the Niko’s even better. They charge reliably and will charge batteries that the Battery Tenders seem reluctant to give a charge. Intuitive operation and simple. I do have some glass matt batteries and like there is a setting specific for those as well. A small number of my batteries are 6 volt so I like the ability to use the same trickle charger for both 6 volt and 12 as needed. All that I have purchased to this date have functioned well and seem well made. Better terminal clamps compared to what comes on the Battery Tenders. I think these are a good buy and all that I have purchased have lasted for years.

Simple, well made smart trickle charger at a fair price.
There is a reason the NOCO GENIUS smart car battery charger is so popular. It works well, it is very simple to operate and solves the major headache for car owners who must leave their vehicle unattended for weeks or months at a time.It used to be when you turned off your vehicle and removed the key, all power was off and there was no drain on the battery. Not anymore, there are all kinds of things that always stay on now. If you have a newer vehicle, you know what I am talking about. I went away for just a couple weeks and when I returned my car would barely start. I didn’t think too much of it but when I went away on a 6 week trip this past summer, I came home to a super dead battery in a 3-year-old car with 20K on it. Nothing worked, no lights, no locks, no trunk, nothing… I even had a very difficult time getting into the electronically assisted doors. Now to be honest, after a couple weeks away, my car sent me an email saying it was shutting down systems to save the battery. When I returned, I measured the battery voltage, and it said 3 volts, it was so dead. I put a charger on it overnight and the next day it was only 6 volts, and it still would not turn over. I was able to get it started with one of those new micro jump start devices that I remembered I had (amazing little devices) and I took it to the Lincoln dealer and they replaced the battery under warranty but said anytime I go away for longer than a week to put a trickle charge on it or remove one of the battery posts to prevent the battery from completely discharging but they really didn’t like that idea and preferred the trickle charge because a bunch of electronic settings will need to be reset once you hook it back up. Moreover, I am seeing the latest luxury vehicles now are coming with two batteries, one just as a starting battery and a separate “house” battery to run all the electronic stuff that is running in the background. That is the way yachts do it. All these car apps that talk to the car via satellite, the various alarm, safety and convenience stuff will kill your battery if you don’t regularly use your vehicle, it is that simple.While this can charge your battery from a very low state, keep in mind it will take a very long time, it really is designed only to “maintain” your battery, and does not do an efficient job charging it from a dead state. Batteries require a charging “profile” depending on the type of battery, most have an initial heavy duty “bulk charge” phase followed by a “float charge” or a maintenance level. This charger only addresses the maintenance charger of about 1 amp or so.So, what you want is a SMART trickle charger that is smart enough to know the battery type you have AND smart enough to know when to stop and start charging at a very low amperage just enough to keep your specific battery type at its optimum charge level for the longest lifespan. The NOCO GENIUS does just that. What I like about it the most is that it is super simple, so simple my wife can do it without freaking out about doing harm to anything. The other thing I like about this is the cost. It is very reasonable and on sale it is a screaming buy. Everyone needs this IMO. Get it and it will save you way more $ than it costs, as well as a massive headache when you come home from a vacation to a dead vehicle that will not budge, and you must arrange to have it serviced in your garage!Positives:• Effective trickle charger• Simpe to connect and operate• Will not do harm to your battery (or cause a fire) from overcharging• Safe for long periods of unattended operation• Reasonable costNegatives:• Not the best charger for charging batteries from a very low state• Will not “jump start” your vehicleI think you will like this useful item, and it will provide many years of service for a modest price.5 stars

Fully charged
After shopping around I went with the 1amp charger since it’s for my boat battery and time of charge is not important to me along with always being told the slower you charge a battery the better. The charger it replaced only charged my lithium 100ah battery to 13.4v. Upon arriving and unpacking it is clear it’s very well made. It took roughly 9hrs to get from 13.0 to the full 14.44. Which is the first time my battery has showed that full of a charge. It’s easy to use and like all the safety features it has in case of me making a stupid mistake. I would recommend this to anyone and though you can get a way faster charger for same or less i would personally just spend more money on this same brand but with higher amps if time of charge is important for you. But for me it’s perfect and can take all the time it needs

Bought this to recharge a lithium ion motorcycle battery. Product worked as advertised. It is compact, versitile, has a good build quality and has all the necessary connections. My battery was below 75% and the charger fully charged it in about 5 hours. As others have mentioned, there were no insturctions included with the unit. However, a quick web search brought up all the relevant instructions and was much easier to read than a small paper printout. Overall, a great value for the money (charging up one battery paid for itself) and I’m sure I’ll get a lot of use out of it.

La batería de mi moto se descargó a 7.8V por tenerla sin movimiento por dos meses. La dejé cargando por aprox. 12hrs y después de eso marcaba 12.7V, se la puse de vuelta y arrancó sin problemas. Es simple de usar y los componentes se sienten de calidad.

I bought the Genius 1 to help maintain the 62ah, Enhanced Flooded Battery (EFB) in my new 2025 Subaru Crosstrek. The vehicle had been sitting for two weeks and the battery voltage reading was 12.4 volts. I hooked up the Genius 1 and the LED was pulsing RED, indicating charge mode. I figured it would take 6 hours or so to charge up the battery and then the LED would switch to pulsing Green , maintain mode.After about 13 hours of charging the LED was still pulsing Red. I thought that at this point it should have switch to the pulsing Green LED , maintain mode. Was my battery being overcharged ?It took about 14 hours for the LED to change from Red to Green. I was relieved to see that it finally switch to the maintain mode. I then unplugged the charger and I let the battery rest for a hour and then checked the voltage.It was reading 12.8 volts. So the battery voltage went from 12.4 volts to 12.8 volts. I wrote this review so that others may have an idea of how long it takes the charger to go from charge mode to the maintain mode.
