NOCO GENIUS2X4, 4-Bank, 8A (2A/Bank) Smart Car Battery Charger, 6V/12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Motorcycle, ATV and Lithium Batteries

I was persuaded to but this unit by the salesguy in Autozone and they dont even stock it (or didnt at this MA location)! He said he uses it and loves it. I took his advice and bought it on Amazon, even thought its relatively expensive compared to some other chargers. Its worth every penny! It can charge up to four batteries at once, clearly indicates (via LED lights) where it is at in the charging process, will not over charge and then (the best bit) keeps the batteries at peak charge, all the time, automatically. I am using it to charge two RV batteries and a yard tractor battery over winter. I love it. I literally just attached the batteries and walked away knowing they will be in great shape this spring. Aaah, peace of mind. Enjoy!!

Got tired of lead acid batteries in my Ryobi riding mower. Swapped them out with some LiPo batteries and used the disconnecting leads here to keep the batteries easily ready to charge after mowing. I just connect the leads back together to charge, disconnect and store under the seat when in use. Zero issues, and it's nice not only to see battery level and status, but also to be sure they're being kept in the best possible health when charging.

Ordered this charger on prime day and finally installed it 4 days ago and everything seemed to be working well. However 2 days later port 3 is now flashing that the unit is under temperature and cannot operate. Emailed support and they say that it sounds like the unit is faulty to send it to them under warranty replacement. Kinda a little miffed that after 3 days my brand new unit needs to be replaced but at least support was fast to respond. Hopefully they are as fast to send me a replacement unit and not the 4 to 6 weeks they quoted. This unit comes with a 3 year warranty so hopefully this will not be a repeated occurance. Unfortunately because I delayed setting it up I am outside of Amazon's return/replace window. I have another charger by this company and have not had an issue with it so hopefully it's just bad luck, but only time will tell. I was impressed with the overall build of this unit and the accessories included with it but apparently something under the hood is less than optimal.Update 1: Reached out to NOCO support and they're responce was quick and efficient with an RMA claim paper. Just have to pay for shipping, which was 30 dollars to ship to the factory in AZ. So far my prime day purchase has not been the stellar deal it was supposed to be. I would have hoped that the company would have provided some means of shipment to them for a discounted rate but no dice. More updates to come.Update 2/11/23 new unit has performed as advertised and shows no signs of quitting. Despite initial unit failing new unit has been great and does a great job of keeping my motorcycle batteries up to speed.

This battery charger helps me keep my lawn mowers running it is also very easy too hook up to you equipment for charging which helps to keep my battery life longer. I've found the quality of the charger to be of good value and safe to use because as it charges the indicator light let's you know the level of charge it has reached. Great lighting.

This is a great product works awesome. I have my four motorcycles charging keeps my battery lasting longer. I will get more for my vehicles and land mower.

Full disclosure, we use other Noco chargers onboard our school buses at our kid's school. They are very robust and keep the dual 12V commercial batteries fresh when the buses are not in use. I got this one for my motorcycle fleet(?) at home. Yes, the charger is more expensive than several similar. It's worth it. I've used Battery Tenders, and many others over the years. The Noco is best.The leads for the battery are not the standard SAE version. Noco uses a heavier duty connection that clicks into place. The alligator clips are designed to be removed if you need to permanently install a lead on your vehicle's battery inside your car. The unit comes with clear instructions. If you are upgrading for an existing SAE configuration, get the Noco-SAE adapter ($16 at this time). Just search in Amazon "NOCO GC009 X-Connect SAE Adapter Accessory Genius Smart Battery Chargers" .

I was saving to use when I install my solar system in my rv, couldn't because of hurricane Milton, but after the hurrican, my rv engine battery was dead, I open the box with this charger and plugged in and found 1 out of 4 charging positions not working, have to send back glad they have a 3 year warranty

What a great product. We use this for our "not so often used vehicles" in our garage. We had the issue of our vehicles not being ready to drive when we wanted to take them out for a weekend spin or up to a local car show due to drained batteries. This eliminates the issue by maintaining a full charge. The multiple ports are awesome and the extension cables make routing a breeze. The size and compact design make it look great and a nice addition to our garage. I also use it for our other lawn, atv and other batteries. Simply connect and it's intelligent system detects the battery type, size and charging needs. Shuts off automatically and will turn back on if it detects a voltage drop. Love this thing!
