## Description

NOCO Genius smart battery chargers are some of the safest and most advanced on the market. One of our best, the G4 4-Bank Battery Charger and Maintainer is designed to charge 12-volt lead-acid and lithium-ion batteries up to 40Ah. It can also effectively maintain automotive, marine, RV, powersport, lawn & garden and deep-cycle batteries. It chargers 2x faster than ordinary battery chargers, can repair damaged batteries and is designed for use with micro-hybrid start-stop vehicles and CANBUS electrical systems. Guided by an on-board microcomputer, the G4 monitors battery activity for safe and efficient charging, automatically minizes energy consumption and provides redundant levels of safety protection, including spark-proof technology, as well as reverse polarity and overcharge protection. It can remain safely connected 24/7, while its streamlined design makes it ultra-compact, portable, and incredibly lightweight. The G4 features external mounting holes and a rubberized base that avoids surface slipping and scratches, while remaining impact, UV and water resistant (IP65). Intuitive LED indicators provide visual state-of-charge feedback and diagnostic information, even when in maintenance mode. Designed for use on 120-volt 50-60Hz electrical systems and includes X-Connect battery clamps with integrated eyelet terminals, as well as a 5-year limited . DC Cord- 60-Inches (16AWG), AC Cord- 60-Inches (18AWG).Charge up to four different batteries at the same time.

Review: Great quality and perfect accessories - I was hesitant to pay $175 to get this, but after reviewing other similar devices I kept landing on this one. I do already own their portable battery jumper, it is very nice quality, made to take a beating and its intelligent. I owned the jumper for about a month to make sure it was good quality. The packaging is very nice, well made and instructions are well made. I am able to charge 4 batteries at once without using up 4 sockets with other better known battery tenders. Note, battery tenders, don't always provide a full charge, they just keep enough current to the battery to keep the cells from dying. This provides a full charge. The case is very well made, water proof and self senses the battery type when you make contact with the battery. You get 2 battery screw connectors for more permanent or long term terminal connections and you get two spring loaded alligator terminals for larger auto/rv battery types. You also get 4 extension cables, so they don't hook you to buy all the accessories. If you didn't want to pull the batteries out like I did from my motors, you can buy additional extension cords for a very reasonable price, you can also daisy chain the extension cords to meet you distance requirement. Overall I am impressed with it, everything seems good quality. This isn't something you open and immediately know its a knock off version from China, its the real deal..
Review: Great product if you store batteries - I mounted this product on the post of a shelf that holds spare batteries. Over time our spares would discharge. Keeping them on a charger was a total mess with wires in a rat's nest. Now we can just walk by and see that the lights are all the way to green. Even new batteries take an initial charge, which is to be expected since there is no telling when they were actually filled with acid. Another incredible use is keeping 12 volt gel cells charged. The charger comes with two 10' extension cords. (All cords have polar connectors for the charger end so you can't plug them in wrong.) I took one of the extension cords and split the wires apart every foot for six inches. Then folded the wires back and put a nylon tie around the wires where the split ended at both points. This gave me nine loops of split wires. I could have split the entire 10' length but that would have made the end result messier and more likely to tangle. At the mid point of each loop I clipped a 3M T Tap connector over both the red and the black wires. T Tap connectors just snap over a wire, insulator and all, and then allow a blade connector to be plugged in. The exact same blade connectors that the T Tap connectors are designed to accept are on 12 volt gel cell batteries. So with our modified charger extension cord we can now maintain the charge on nine gel cell batteries at the same time. This is the link for the T Tap connectors : http://www.desertcart.com/3M-Scotchlok-Self-Stripping-QuickSlide-Disconnect/dp/B003KOIBLI/ref=sr_1_1?ie=UTF8&qid=1351600013&sr=8-1&keywords=3m+952 The only complaint is that this charger is intended for four batteries at the same time. However there are only two charging cables with electrical clamps. The other two have holes at the end which I guess is for batteries with threaded connectors and wing nuts. If you have more than two batteries with plain posts then you are forced to find another way to keep them connected. If you want to have four clamp connectors instead of the two it comes with then you have to buy two of these: http://www.desertcart.com/NOCO-GC001-Genius-Battery-Connector/dp/B004LWV0DY/ref=sr_1_21?s=automotive&ie=UTF8&qid=1351600268&sr=1-21&keywords=noco+genius

### ⭐⭐⭐⭐⭐ It's solid.
*by T***G on January 31, 2018*

I guess you'd say I'm a fan of NOCO chargers. A few years ago I bought a G1100 to keep my '67 Fleetwood charged, then another to keep my '62 Falcon charged, then a G750 to keep my lawnmower charged. I had such great results with these chargers over the last couple years I invested in this gigantic beast, partly for the extra features and partly so I could move the G1100s and use them for other purposes. I've had the G4 for a little while now and it does everything expected. Knowing what I know now, I should have just bought the G4 years ago instead of starting with the G1100s, but you know, it's hard to stomach a $200 battery charger. I think Noco makes good stuff, and I've got a few years of positive results to back that up. If you've like me and have a lot of batteries to keep charged, I'd just bite the bullet and get the G4. It's solid.
