NOCOGENIUS2, 2A Smart Car Battery Charger, 6V and 12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Motorcycle, ATV, Lithium and Deep Cycle Batteries

I would go through the problem of not having to use my car for long periods of time which would ultimately drain my battery. I would suffer through by using a portable jumper, but the problematic battery would persist. I started investigating in alternatives like unplugging the battery from the car while it is not in use, but I would still have to get a new battery regardless. I luckily stumbled into this product that changed the game entirely.My battery was absolutely drained and would not even crank the starter motor. I got this product and set it up using the instructions and it charged up right away. It was very practical to use with ease. All that is needed is to latch on to the terminals in the appropriate order, plug it in, and in the push of a button it revives the battery. I was able to recharge my battery back to 100% over time and it starts without a hitch. I would just leave my battery connected to this product and check up on it every once in a while. Very simple, very effective. Highly recommended.

Very nice, it worked well for me! Charged a dead battery I had my doubts but it’s works.Compact and works great! It worth the price

My landlord has his car here for storage but needs it every now and then. I was about to take it out to keep the fluids going and found out the cars dead. Tried a different but popular brand battery charger maintainer and after a jump start. Let it charge overnight. Woke up to try it again and found out it was dead still.Got this shipped same day and immediately it started charging the battery without needing the force charge. Let it sit overnight and surprised the performance was much better. Yes it's slowly charging (box says 30 hours or more) but the connectivity is reliable and strong. Temperature I noticed was warm but not hot. And checked on it again and saw the indicator went to above a quarter charged which is already much better.Small and powerful, it will charge batteries from dead but it is a slow charge. Very much value for money when it is on sale but it works so well I'm going to use it on my weekend car that sits in the garage or maybe buy a second one because it works so well and has options for other kinds of batteries!

I love this powerful little charger! It's so much easier to use than my old, clunky one - no need to find a small table or stand to hold the charger next to the vehicle while charging, just hook it up and leave it resting near the battery under the hood. I purchased this to give my Mini Cooper a boost when needed since there are periods in winter when I don't drive it, but I'll definitely use it on my other vehicle battery as well. I will say that you need to be patient - the first time I used it I thought it might be defective because it took so long for the indicator lights to move off the first charging "step". But the first step seems to be the longest, as after it was reached the lights moved to "fully charged" pretty quickly. The whole process took about 9 hours for me, but that will vary depending on how discharged your battery is. I'm so glad I happened to see this great little device on a YouTube video!

I use this on my UTV, motorcycle, and lawnmower. Works great and I love the small foot print. The one thing I would change is to make the clips smaller so it can fit on the battery post better. I had to remove the cables on my motorcycle to use this.

The NOCO GENIUS2 is incredibly easy to use, and it did exactly what it promised. My battery was completely dead, and this genius device revived it perfectly. A lifesaver and well worth the money!

I have a 18 year old riding mower. About every 2 years I have to replace the battery, where it won’t crank again even if it was just shut off from running for a while. Put this on the old battery and it’s now working like brand new. Multiple startups without having to jump off the battery. I was doubtful that it could “refresh” an old battery but it works. Saved money, didn’t have to replace the battery.

I really like the way the updated charger keeps my lithium ion motorcycle battery topped off. Robust design and small enough to provided the correct power to keep my battery in peak working condition.
