Tempting Reviews –
The instructions are VERY hard to follow – because they made a lot of assumptions.This is to try and help those who were wondering. You’ve got 3 things to verify first.1: What KIND of battery are you charging? This is critical and you can only know this by searching the label on Google to figure out if it’s AGM, Lithium or other. (For purposes of this writeup I am assuming you got rid of your old clunker years ago and thus your car came with an AGM battery. Most cars sold after 2012-ish are going to have AGM and if it’s a hybrid it’s almost certainly an AGM. If it’s not AGM you’ll want to research your specific type.)2: What problem are you trying to solve? Sounds simple but it isn’t. There’s a difference between a DAMAGED battery, a DRAINED battery (as in there’s no charge at all) and a LOW battery. A DAMAGED battery is unlikely if this is the first time you’ve had an issue. A DRAINED battery is likely if your car (or whatever device) hasn’t been driven or even turned on in at least two weeks. A LOW battery may indicate the battery needs to be replaced. This device can help with all three, but it’s critical you understand what YOUR situation is. If you don’t know, don’t just buy this, get it towed to Autozone or whatever; they test batteries for free.3: How urgent is your problem? Meaning, if you’re stranded somewhere, you need to be calling a tow truck instead of researching this; it’s not going to help UNLESS you’re very near a power outlet. If you’re at home you’re probably fine, but you’ll likely need an extension cable depending on how your place is laid out.OK, so after that, here’s the run down.1️⃣ connect the charging cables to the device, then attach the charging cables TO THE BATTERY – DON’T PLUG IT INTO THE WALL YET. If you have a hybrid I know they say jump it from under the hood – don’t. Just attach straight to the battery (for hybrids it’s likely in the trunk behind a side panel). The reason for this is that there could be a defect in the line (thus why your battery’s in the state that it’s in). There should be one “pole” or post that has a (+) sign, that’s positive, or look for it under a red colored rubber cover. Connect positive (red) to this, then connect negative (black) to the other post, BEFORE plugging the device into the wall. Attach to the battery first. If your battery isn’t dead, you may get a spark, that’s fine. It’s a clue that your battery still has at least some juice.2️⃣ plug the device into the wall outlet. The device should get an amber standby light (the power symbol). If you don’t get this check if your outlet is one that has a fuse breaker (the two buttons) and see if you can reset it. Also verify this outlet has power; plug something else in; might also be powered by a switch somewhere. In other words CHECK THE OUTLET BEFORE YOU ASSUME THE DEVICE IS DEFECTIVE. If you check all that and still don’t get a base amber light, the device MIGHT be defective; but check step 3 first.3️⃣ Tap the MODE button once; it does take a bit of effort to push it in. It should light up 12v. (if nothing happens, it’s likely defective). DON’T LEAVE IT ON 12v. Keep tapping until those lights are off (and ideally the amber status light goes back on). This is where you need to know the battery type; it’s likely one of these three. HOWEVER…THIS SETTING IS FOR MAINTENANCE AND TRICKLE CHARGE, NOT FROM-ZERO CHARGING. So chances are, if you bought this device, this setting is NOT what you need YET. Proceed to Step 4 (this step was just to test the device to make sure it wasn’t DOA).4️⃣ This is a bit tricky – but tap the MODE button once (lights up 12v), then TAP AND HOLD for 3 seconds (literally count alligators in your head), then release (yes, you need to say “alligator” the third time). The light should go down to the second row with 6v on the right. Now, you’re back to tapping and the light will cycle to the left.IF YOUR BATTERY IS NOT DAMAGED – and the way you’d know that is whether it holds a charge or not – YOU WANT “12v Supply”. This will not give you an obvious indicator level, but if you need to jump this car, this will let you do it. It’ll basically give enough juice to the battery to allow it to turn over – use the car’s interior lighting as a clue. You may need to leave it on for a half hour or so just to make sure there’s enough for the initial draw. (Once you can get the gas engine going the alternator will complete the charge after you drive for about 30 minutes; otherwise see Step 5).So basically treat “12v Supply” like a jump. It’ll give you enough to complete the charge; if it doesn’t hold, you can then go to “12v Repair” and let it cycle, but that’s only if the battery has been dry for a very long time, usually. DO NOT LEAVE THE BATTERY PLUGGED IN ON 12V SUPPLY THINKING YOU’RE DOING GOOD – YOU’RE GOING TO DAMAGE THE BATTERY AND LIKELY CAUSE MORE PROBLEMS. This is because at some point there’s going to be feedback going the other way. That’s NOT what you want.5️⃣ After it’s been on “12v Supply” for about 30 minutes to an hour – just enough to have some base life, you can now tap MODE twice to go back to the maintenance mode I mentioned before, then (and this is critical) TAP UNTIL THE TYPE OF BATTERY YOU HAVE IS LIT. This is so that the charger will provide charge in a way that is healthy to the battery.You will also get the level indicator at the top to start working correctly (this works even if the battery’s dry, but from dry, it can’t hold enough charge to increase; you’ll just see it bounce from one to two and back to one over and over again while lights flicker. That’s why you have to do “12v Supply” first to give it enough to hold from regular draw (your car is always drawing from the battery for something or other), THEN do the maintenance setting if you want to go all the way to full and keep it there if you can’t (or don’t want to) drive it right away.One possible misconception with this device is the assumption it does all of the above automagically. It does NOT. You can leave it on maintenance mode but it’ll never charge, I promise you, and you can leave it on 12v Supply but you’ll have a problem if it charges for too long. 12v Repair seems to be more about testing the drain, so I suspect it won’t “harm” anything, but it likely will shorten the life of the battery if left on too long, especially if you don’t actually need it. Put it this way – if you’ve never had a problem starting your car until that ONE time during the pandemic that you stopped driving for weeks, you likely DON’T need 12v Repair. You likely just need to charge it up a bit, then put it in maintenance mode for however many days until you next drive; I would even suggest not leaving it plugged in but maybe plug it up for maintenance mode once a week or something for a few hours, just so that there’s drain-and-charge.6️⃣ Once you get the green indicator the device believes that the battery is full. At this point you can (theoretically) leave it connected in maintenance mode, or just plug it in as needed. To remove the device, remove things in REVERSE ORDER – Tap MODE until it’s in standby again, then remove negative (SET IT A VERY GOOD DISTANCE AWAY FROM METAL), then positive (SET IT A VERY GOOD DISTANCE AWAY FROM NEGATIVE AND METAL), uncouple the charging cables, then unplug the device from the wall.You are (or should be) done.One other thing I might suggest to you is to consider a portable AC generator. They go for fairly cheap here on Amazon – that way if you do get stranded somewhere that doesn’t have a power outlet, you can use those for that initial jump. Something else to consider for your emergency roadside (self) assistance. I have two emergency type devices – one’s a powerbank: https://www.amazon.com/gp/product/B07LBLQ9YY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1The other is an actual portable generator: https://www.amazon.com/gp/product/B07MYT6SZ5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (no longer available, but you can look some of the related similar products) which has other helpers like a light and USB outlets – could be a saver if you’re literally in the middle of nowhere when your battery acts up.

I had this thing for two days, connected to both my motorcycle battery is which quite old but the old tender was indicating 80% batter all the time. The Genius’s 10 has the 25% red flashing light 100% of the time for both my car battery and the moto. I tried regular mode, AGM and repair and its always red flashing or it goes it shuts itself off over time. The voltage appears in the fully charge area. I can’t seem to be able to trust this product at the moment. (may have to return it…) updating review. Somehow the battery just died, the noco finally fully charged the battery but it was still unable to start the bike. The battery was holding 15 volts but unable to start the bike. Replaced the battery and the bike starts with no issue. I think the product could have better instructions. I saw an independent video, where perhaps the noco could have now repaired the battery.

Used it to charge a battery that was 3 yrs old and dead due to the car being driven very little. It was also low in fluid, added distilled water to bring it up to proper level and set to ‘repair’ mode overnight. Next morning car started up instantly! No issues. It has been over 3 months and still no issues starting it up, even on cold mornings. Now charging another dead battery in ‘repair’ mode and will see how it does with that one. Will update with result.

Noco worked well till yesterday late November , and I would like to send it back for a replacement or repair since it’s been less than three years since I purchased a product and I have the receipt. Purchased product Feb 21, 2020How do I return the product or contact the dealer.

I’ve been through a lot of battery chargers in my day. But I needed one that could charge my new RV lithium batteries, so I took a chance on this unit.It’s great: Easy to set and use, takes up little space, works with several different battery types, persistently coaxes my batteries back to life. And keeps them charged.At first I was startled by the unit occasionally flashing three red LEDs. But I looked it up and found that it just needed to cool off, and after a bit it would get to work again. And I decided this was a feature, not a bug: it’s nice that (a) it doesn’t overheat; and (b) it resets itself.

I have a Dodge RAM 2500 with dual batteries, one or both of which were not properly holding a charge. This NOCO charger allowed me to restore the charge sufficiently enough to get the truck started. However, the batteries would not hold the charge and had to be replaced. I honestly had not looked into AGM battery technology until this product made me aware of it. I replaced the batteries with two AGM Diehard’s and continue to use this device in cold weather to keep a trickle charge on the batteries.

Very well made with high quality materials. It seems very durable. Extremely easy to use. The physical size of it makes it easy to pack when traveling. It fit my needs perfectly.

The first one we ordered had misaligned connections. I had purchased it a few months ago and hubs finally got around to needing it when he discovered the problem. We contacted the company and it took about 5 days and many emails/pictures for them to decide to replace at our shipping expense with a 4-6 week turn around time. Amazon still had us in the return window so we opted to return and reorder. The second one aligns fine and has done a good job charging/repairing an old golf cart battery as well as our camper batteries. We almost went with another brand but our other NOCO products have been great.
