= Cutting-Edge 5-Steps Charging, Highly Interactive =


Using a unique charge algorithm, the TOPDON T1A smarter battery charger goes through revolutionary 5 steps to constantly read and communicate with the battery, charging only to its direct needs, and therefore avoiding any possibility of incorrect charging:

1.Battery Analysis & Diagnosis – Check the battery’s initial condition, including voltage, state-of-charge (SOC), and health, to determine if the battery is stable before charging.

2.Battery Desulphation – Use voltage or high-frequency pulses to break down the sulfates that have built up over time in your aging battery, to extend battery life, and optimize battery performance.

3.Battery Bulk Charge – Begin the Bulk charging process based on the condition of the battery, and return 80% of the battery’s capacity.

4.Absorption Mode – Bring the charge level to 90% by delivering small amounts of current to provide a safe, efficient charge. This limits battery gassing and is essential to prolonging battery life.

5.Battery Float Charge – Maintain the battery fully charged, without boiling out electrolyte or overcharging, to improve the battery life.

Battery Diagnostics

Before charging, the TOPDON TORNADO1200 battery charger will automatically analyze & diagnose your battery, accurately charging and maintaining it at the same time.

    The charger works as advertised. As with any charger it is important to remove any latent surface charge from the battery so the charger can read an accurate voltage. I found this charger read accurate battery charge. If you find it was at say 70% while charging, you disconnect and reconnect and it says 100% that is the surface charge. Turn your headlight on for 30 seconds before connecting the charger the second time and it will read accurately.

    Works. Charges. You have to encourage it a bit on dead batteries as it sometimes registers them as no good. Just keep turning the unit on and off and it will eventually start charging.

    Attached the unit to the Optima Red top battery in my Jeep. The display showed 50% charged and started charging up to 62%. It just stayed at 62% for over an hour. I turned it off disconnected it and then reconnected it and it showed 100% charge. I then turn the unit off disconnected and reconnected and it showed 62 once again and then charged up to 68% and then stopped at that percentage. My fluke meter showed that the battery was charged to14 volts and was more than fully charged even though the display showed it was not. I believe if I left it overnight it would have ruined the battery. The battery charge on the display was 12.5 but my meter showed almost 14. I’m very disappointed in the lack of quality Schumacher has now. Based on other reviews, I am not alone. When I requested to return the battery Amazon said I need to deal with the manufacturer so I called twice and left messages twice and have yet to hear from them. Shows a lack of quality control and lousy customer service. Buyer beware.

    The product works as advertised . My main two suggestions are :1) needs to automatically recognize what type battery is being used and autoselect the mode2) needs longer cables for the allegator clamps

    I received this about a week ago and used it to charge a pick-up battery. I took it out of the box, hooked it up, and then tried to use my intuitive sense to turn it on. It did not seem to charge correctly, so I read the provided manual–which is difficult to read and understand. “On some settings, you may have to select and then hold 3-5 seconds.” Well, which ones? After I read the manual twice, I think I understand how to use it. I say “think” as I am not sure. I found the manual very marginal. I then went to the NOCO site and found a data sheet, but no instructions. It is the weekend, so no chat available. It did take 16 hours to charge my battery, which seems a bit long for a supposed 10A charger. That is also what the chart showed for the charging time (17.3 hrs). What do I like? It is supposed to charge all types of batteries I use, it is compact and rugged. All that said, I hope this becomes my favorite charger once I am sure I am using it correctly.

  6. Photo/Video Gearhead

    My car battery was discharged to the point that my Battery Tender Plus 1.25A charger/maintainer would not even attempt to charge it. I purchased a Noco Genius5 charger/maintainer that has successfully charged my battery without requiring that I activate Noco’s ‘force mode’ that will charge a battery that has become discharged to 0 volts.Below are three points to keep in mind if you decide to buy a Noco charger/maintainer.1. Select the correct Noco for your battery. Each Noco is rated for a certain number of Amp-hours (Ah). The Genius2 is rated for 40Ah, the Genius5 is rated for 120Ah, and the Genius10 is rated for 230Ah. My car battery’s capacity is 92Ah, so the Genius2 would not be able to fully charge it; however, the Genius5 is able to fully charge it.2. Be patient because the Noco may require longer to charge your battery than the owner’s manual suggests, for two reasons. First, the ‘25% charge’ step includes a de-sulfation process that can take some time – for my discharged battery, more than 24 hours were required for this step. Second, the ‘100% charge’ step includes an optimization process that can also take some time. So, whereas the Noco spent only a few hours in each of the ‘50% charge’ and ‘75% charge’ steps, the ‘25% charge’ and ‘100% charge’ steps required more time.3. As the Owner’s Manual indicates, you MUST disconnect your battery from your vehicle prior to activating 12V Repair mode; otherwise, you risk damaging your vehicle’s electronics.

    I have a GEL battery, cost 178.00 brand new. It has been dead for 3 years. Just couldn’t stand the thought of throwing it away. I used that battery for everything when traveling,,,,,, run into someone who needs a boost… Just take the battery over to their vehicle and it works fine. Need some lite for you camp. Just hook up the battery….. and on and on. Well it I left it connected and it drained a few times and it pretty much died.Fast forward 3 years, it took 3 days and 3 “Repair” cycles.The battery is back.I have a truck that regularly drains and sulfates its batteries.Repair 3 time and this last battery came back to life.It really does work.Oh and it charges up dead batteries too…. 🙂

    I have a truck that mostly sits in the garage. Every time I need to back it out of the garage, the battery is dead.I know that just sitting isn’t good for batteries, not to mention this battery is several years old.Now keep in mind, this is a large amp battery for a SUV, which was so dead, a turn of the key and I didn’t even get lights on the dash. I stuck this little charger on it and it took a day and a half, but it charged completely. Ok, now I’m beginning to get a tad impressed.I have two of those old type chargers, you know the ones that after a while you can hear the acid boiling inside the battery, and the battery is getting really hot… you know the chargers that tell you not to leave it on your battery for any extended period of time as this might (will) damage the battery (possibly even start a fire). Well… no more.I’m a total convert now to using smart chargers, and this one seems especially good. I really hope I don’t find some little something that breaks 6 months from now, cause I really like this charger! It seems very well designed and made and most of all, it works great.The only negative I can find, it has a single button to select one of several charging modes, and LED’s to indicate which option you have chosen, and those LED’s are pretty much self explanatory, as well as an advanced mode where you have to push and hold the single button to enter advanced charging mode. For example, if your battery is so bad, the charger cannot detect there is even a battery hooked up, you can tell it to go ahead and start charging anyway which is a really nice feature. As another reviewer mentioned, when you need to use some of the more advanced functions, if you’ve lost the booklet, well… good luck. The multi-language booklet briefly explains all of the options, what the LED’s mean, and that’s pretty much it, verbose it isn’t..It comes in a really nice packaging, like you’re really getting something ( and you are), the unit itself seems well made and thought out, you would think a bit more of an effort would have been put into the manual.But, perhaps the product speaks for itself… and it does. And, after all most users will hook it up to their 12 volt car/boat/motorcyle battery, plug it in, select the regular 12v battery option, and that’s all most will ever need. Once the battery is charged completely, the charger senses that, and switches automatically to just maintaining the battery. If you loose power while charging (or maintaining), this charger just picks up right where it left off, so there is no worries about pushing buttons or selecting modes, it knows what you were doing before, and starts right back up with doing it again.Am I glad I got it: YesWould I buy it again: Yes.

    Genius10 10 amp charger. Works great with my AGM deep cycle batteries. That last 10% of charge blinking green takes a long, long time before going solid green at 100%, but that’s how AGMs like to be topped off…low and slow. These newer Genius chargers (the all-black 1, 2, 5 and 10 models) have been improved for lithium phosphate battery charging by increasing the charging voltage in Lithium Mode from 14.2v in the previous versions, to 14.6v in these newest versions. This allows for better charging to full capacity for these types of Lithium batteries.

    I used this battery charger to keep my car battery always full especially during pandemic because I need to work from home so I don’t drive every day. I realized that my car simply sitting in the garage for two months so this battery maintainer is capable to deliver high current on demand and offers a relatively service to keep the battery in charged. So now I feel that I have saved myself $90 for not needing to replace a new battery.When it comes to automotive products and battery chargers, NOCO is a well-known brand that offers several products in a different league of their own. Since 1914, the company has been a trusted name in many mechanic garages thanks to the product line’s durability and resilience. Many car chargers tend to be bulky and difficult to move around, making it even more difficult to use with multiple vehicles. The charger boasts some surprising abilities to bring near-dead batteries that you’d normally replace back to life again. For standard 12-volt batteries, it does a good job of intelligently reading and assessing the status of the battery to apply the correct settings for the best charge possible.A fully automatic car 12 Volt car charger that is lightweight and compact and simple to use. This NOCO car battery charger is so much more than a trickle charger. It is ready to go whether it be your car, bike, ATV, RV, golf cart or any other similarly operated equipment such as generators. It has few stages to its charging process, initialization, bulk and absorption mode and float or maintenance mode. Once it detects that the battery is fully charged, it will switch to float or maintenance voltage and maintain your car battery for you, should t it fall again, it will resume. They are suitable for use on 6 and 12 volt AGM, GEL, WET and lithium types and are the perfect product for the professional as well as the individual home user. Red and green indicator lights let you know the status. It also includes battery ring terminals and alligator clips for easy hook up to your battery.It will monitor you’re their life and switch between modes going from charging mode to float or maintenance mode once your battery is fully charged thanks to its high-frequency smart technology. Built-in circuit protection protects your battery from overcharging, reverse polarity or short circuit. An intelligent offering that will work for both 6 volt and 12 volt and maintain them once full. It will work for lead-acid ones up to 30 amp-hours and it will work twice as fast as a standard charger and if need be repair damaged ones.They are impact, UV and water-resistant and will mount to all AC outlets. I used it with AXTRA 8-outlet power strip because the 9-foot power cord is very helpful for the battery charger to reach the battery. It offers spark-proof technology and reverse polarity as well as overcharge protection for your peace of mind as you stay connected all the time. The LED indicators will indicate the status of your battery even when in maintenance mode.

    NOCO battery charger fully charged my car battery. I parked my car at my front yard during quarantine and the battery was very low so I used it to charge the battery. Too bad the power cord couldn’t reach to an AC outlet from the house so that I have to use with 9 food long cord AXTRA power strip to deal with the battery charger. This unit simply makes the charger itself sit nicely under the hood with included mounting strap.NOCO battery charger and maintainer combo come in at a budget price with some advanced, smart features to protect the battery, your vehicle and possibly yourself. As a result, this is a good maintainer option to consider if you want something that takes away the danger and challenge of bringing an automotive battery back from the dead. Its portable size also makes it a great option to bring around on trips.The 2-Amp battery charger and maintainer that works with all types of 6- and 12-volt lead-acid batteries. This versatile all-in-one battery charger and maintainer is ideal for keeping your vehicles fully charged and maintained all year long, especially during long-term storage. It’s extremely easy to use as well, simply plug it in and let the NOCO will automatically monitor and maintain your car’s battery. The optimized charge mode is designed to safely charge your battery, using advanced charging technology to monitor and maintain your battery. It’s safe to leave this plugged in and maintaining your battery all year round, as the onboard microcomputer will minimize energy consumption. The rubberized base is designed to both avoid slipping, and protect any surface the battery maintainer is sitting on from being scratched.In addition, this product offers an advanced desulfator repair mode that can help reverse the damaging effects when a battery is left uncharged for an extended period of time. Safety features include sparkproof technology and reverse polarity protection. Force mode feature is awesome to detect low voltage on a battery to start recover process. Usually a low voltage battery would be 1V-4V. Noco claims the charger can charge a dead battery as low as 1-volt. To access force mode, please ensure the charger is connected to AC outlet, press and hold the mode button approximately 7 seconds.

    I purchased this because one of the customer questions on Amazon was answered by the manufacturer as follows:Question: Can I use this to maintain the charge in my car and leave it unattended for months during winter storage?Answer:Yes, it can safely maintain a battery all winter long.By NOCO Support MANUFACTURER on December 9, 2019However, as you will see on the cover page of the user manual (image attached) it says not to use it unattended. (I added the red highlight in the attached picture.)I’m sure that it will probably work, but the point is that this is not a must-have purchase. I bought it for peace of mind and convenience on a car that would be stored through the winter. However, that peace of mind is out the window if the manufacturer feels they need to make a disclaimer upfront.Bottom line, it may work as charger, but it is not (according to the manufacturer’s manual) recommended to maintain batteries unattended. I suppose the battery maintainer portion is technically true if you are willing to move into your garage and sleep with your car during the winter months [grin].

    I will get to how this charger performed in just a moment, but first, let me just say if not for other reviewers alerting me to what to expect, I would probably have returned it as defective just like apparently a number of other people purchasing it for the first time and this is entirely the fault of the manufacturer sending it out with instructions written by people who clearly know the product inside and out, but relative to why and how most people buy it, could not possibly be less helpful, hence my rating of a 3 only out of 5.Lets begin with the basics; for all of its advanced features, this is only a 2 amp charger, there is a general formula described in the instructions to calculate charging times depending on the capacity of the battery and most people buying it because of its low price have no idea that under ideal conditions this thing will literally take days to bring back a typical 12 volt AGM battery, in the course of bringing a battery back while desulfating the indicator will cycle back and forth from charging to defective meaning you have to keep starting it and restarting it until it remains charging and nowhere is this spelled out for the benefit of most people trying it out for the first time–so there, that’s the first thing.The second thing the instructions don’t make clear is how to access ‘force mode’; the instructions say to press and hold the mode button for 5 seconds (the video says 7 but hey, why nitpick?) and try as I might I could not seem to make it work, which is apparently a real big deal if the battery, like mine, was fully discharged at the time, until I accidentally happened to try it before connecting it to the battery and darned if it didn’t work then–pay attention now–to utilize ‘force mode’ the charger has to be plugged in to an outlet, but NOT connected to the battery at first and judging from other reviews, there’s a lot of people who never figure it out and once again, you won’t find this either in the instructions, so for all the forgoing reasons I cannot give this product my highest rating, even though technically it delivers everything it promises–yes, that’s right.So you wanted to know how the thing actually works once I actually figured out how it works? In a word–once you get past the instructions, or the lack of which thereof, it is simply an amazing product for the price!!How amazing? My 90 amp something 12 volt AGM battery was completely discharged and sulfated up the yang when I hooked it up on a Tuesday evening, and at first it would only manage a few hours charge before giving up with a defective battery/will not hold charge indicator–but each time I hooked it back up it was able to run a little bit more and I hoped after it ran for 12 hour stretches that it was finally turning the corner, but it was still not able to hold a charge through Wednesday when I came up with a way to make it run in ‘force mode’ (see above) and sometime around Friday evening it finally made it past the first indicator bar, and by Saturday evening it made it past the orange bar and as I write this on Sunday evening the green indicator is flashing–it has been well over 100 hours, exactly as the formulas out there suggest, but the battery looks to be well on its way to being fully restored–YES!!Now if they could just fix the documentation…

    this battery maintainer/charger is suppose to be able to recognize when a battery is fully charged and maintain the battery. I dont know if i got a defective noco genius 1 but mine DID NOT recognize when battery is fully charged and kept charging. I heard boiling water noises within my 12V sealed battery and unplugged it. I tested the battery a day afterwards and it was fully charged while noco had it on red light (below 75%). DO NOT BUY BEFORE YOU DAMAGE YOUR BATTERY OR BURST THE BATTERY. I suggest amazon remove its best seller and amazons choice labels until further investigation of this product to deem its safety.

    Works great for maintaining. I have a car with a AGM that only goes out once in a while and I throw this on for a day and battery is back up to snuff. I also have a noco genius that I purchased about a year ago for a lot more $, this does everything that one does for much less. Only have had it for a few months but is almost always on one of my rides and so far no problems at all.

    Appears to be desulfating some of my older deep cycle 6 volt batteries. The batteries seem to be holding more charge than when I tried charging them before with another charger.
    I understand it could takes weeks of charging/ desulfating lto restore these batteries to useable condition.
    The cables with the clamps seem a bit small gauge but seem to be working well enough.

    It did rescue an extra car battery I carry to power up an inverter from 12vDC to 120vAC. It is compact and shows the charging status all the way through. The desulfator feature did work as advertised.
