🔋 NOCO GENIUS2: Advanced 2-Amp Smart Charger for 6V and 12V Batteries - Battery Charger, Maintainer, Trickle Charger, Desulfator. Includes Temperature Compensation. Review

This product saved my batteries! A few years ago I installed lithium ion batteries in my golf cart. We forgot to plug it in and the batteries ran out of breath during a very cold spell. None of the other charges we tried helped get them back. I thought I lost $3000. I don't know what kind of magic it is, but it's definitely a Guardian.

This little charger is amazing! I have used it successfully to return 3 ATV batteries that have been sitting for almost 2 years. All were ice cold and showed no voltage when the meter was turned on. It takes time to charge them, but it's better than buying new ones. In my opinion this little device paid for itself and then I saved the money by not changing batteries. The first battery has been running perfectly on my quad for a week! I haven't had any problems with the charger so far and I…

Incredibly disappointing piece of junk. I've been struggling with this thing for a month to get it to work, which admittedly happens sporadically, possibly accidentally. The car is only 1.5 years old and as it has been sitting in a parking lot most of its life I thought it would be wise to keep a battery powered air conditioner on it. Good idea, bad product choice. This thing only lasted so long that I couldn't bring it back through Revain. Now after weeks of frustration with this thing it is…

Advantages:1. Very compact.2. Wall mount included.3. Beautiful appearance.4. Long cord on the wall.5. Good quality clips.6. Beautiful packaging.7. Can force low voltage batteries to charge. Your previous devices that I bought couldn't do this and I had to use a different Deltran charger to get a high enough voltage to charge the NOCO. Cons: 1. Not stated on Revain or their website (as of now) that it can only charge batteries up to 40Ah. I figured as long as you charge it long enough you could…

Updated 9/26/2021: I recently purchased an AXTRA car battery charger and it works well with 6 and 12 volt AGM batteries. The price is better than NOCO 2. However, mobility with NOCO is better. I don't need to take this car battery with me when I travel, so size doesn't matter. I've attached a few photos for comparison. Both car chargers are excellent for maintaining a 12 volt battery. The NOCO charger fully charged my car battery. I parked my car in the yard during the quarantine and the…

I'll get into how this charger works in a moment, but first let me say that I would probably have returned it as faulty if other reviewers hadn't warned me about what to expect as obviously no other people did who are buying it for the first time and it is entirely the fault of the manufacturer who sends it with instructions written by people who know the product inside out but compared to why and how most people use it buy it couldn't be any less helpful, so my rating is only 3 out of 5. Let's

I have a 3 year old 12v AGM battery that has taken a lot of abuse as I only drive 4 miles to work and only do longer trips every two weeks. Lately I've been staying at home because of the coronavirus and driving out about every three weeks. Needless to say, the battery died and I couldn't start my car. All lights went out when the car door was opened. I bought Noco Genius2 to try it out. I was amazed at how small it was. I checked my battery with a voltmeter and it was 1.9v. I plugged in the…
