NOCO GENIUS10 Battery Charger Review, In Depth

[@charlesmcgehee3227]

Good review. Note this: some batteries, depending on the capacity and condition, will take up to 48 hours in the maintenance mode, to fully reach 100%. The single green LED will pulse until the DC voltage reaches 15.5 DC. (FACT CHECK THAT) Then the LED will turn solid Green. This is not stated in the directions, but NOCO tech support will "school" you if you are having trouble. I recharged up a standard 585 CCA lead acid battery. It took around 36 hours before the Green light turned solid. To convert the CCA to Ah, multiply the CCA rating by .7 (.725 to be precise.) I have used NOCO products for a few years now. This Genius 10 is a fine unit.

[@mr.kaband4345]

Yeah I was wondering about how long it takes even with a 10amp charger it take forever I had disconnected before full charge since I tought it be done is 24 hrs but apparently I was wrong

[@ninjazzrhythm400]

Thank you. I was wondering about that pulsing green if it was done.

[@mr.kaband4345]

NinJazz Rhythm my 70 amp battery took 4 full days to charge until I got a solid green

[@axlef1513]

Thank you for this note. This was very helpful. I thought something might be wrong when after a day the green light has not yet turned solid.

[@PouchMaster]

Yeah thanks I was totally wondering about that too! Must be like it really has to slow down from bulking the battery but then it like takes a long time to force that last little bit slowly!

Thank you for sharing! I just purchased one and received it in the mail today.

[@roryorbit]

Very good video. Very informative and clearly explained. One thing you could add is the different ways the 4 charging lights(red red orange and green) behave in different scenarios relating to the charging process. I’ve noticed with the batteries I’ve been charging over the last few days that the solid green is really the only one that signifies that a battery is actually fully charged, would this be correct?

[@HighTechBatterySolutionsInc]

Yes that is correct, the solid green LED will indicate your at 100% state of charge.

[@Shanester66]

Is it every necessary to use repair mode on a 12v AGM battery? If so, should you use it every so often as a maintenance tool?

[@waa2100]

Best review so far. Thank you sir

[@Retaile23]

Very clear and concise overview.

[@sirkildalot8409]

I just bought one of these as I have a deeply discharged battery and I wanted a charger with the force mode. To begin with however I just wanted to charge a standard 12v car battery. When I plugged it in I expected a steady progression through the charge level indicators from one red block through to the full bar (two reds, an orange and a green). What actually happens is the first red blinks for a while, then the first goes solid and the second blinks a coup,e of times then it goes down to no lights then, after a while it goes up to the Amber for one pulse then back to nothing. It doesn’t seem to progress through the bars but seems to be going up and back down? Is it charging? Is the battery OK? Why don’t the instructions tell you what to expect and what the changing lights mean?

[@HighTechBatterySolutionsInc]

Leave it connected, it sounds like you have an issue with your battery - possibly that it's not retaining the charge. The charger will error out if the battery is not recoverable.

[@keithtaylor1531]

Very nice review. You talked about Force mode but how do you put the charger into force mode??? Thank you in advance for your answer and time. It is very much appreciated

[@HighTechBatterySolutionsInc]

If battery voltage is too low for the charger to detect, press and hold the mode button for 5 seconds to activate Force Mode, then select the appropriate mode. All available modes will flash. Once a charge mode is selected, the Charge Mode LED and Charge LED will alternate between each other, indicating Force Mode is active. After five (5) minutes the charger will return to the normal charge operation and low voltage detection will be reactivated.

If your battery needs to be repaired will it automatically detect this and do it for you or will you have to select it? And if you’re unsure if you put a perfectly fine battery on repair mode will it damage it the battery?

[@HighTechBatterySolutionsInc]

The charger will detect sulfation during its regular charge mode and begin the repair process as part of the algorithm. I always caution people to not overuse the repair mode. Due to the higher charging voltages used in that mode, it could shorten the life span of AGM batteries if used excessively.

[@MapleMarmite]

Nice review. What voltage does the charger allow the battery to drop to before it kicks in and starts charging again? I had mine get my battery up to about 14V and when I checked on it a couple of weeks later it had dropped to 12.5(ish)V and the green light was solid, indicating full charge still. I switched the charger off and on again and it started the charging process and had the battery back up to 13V in a few minutes. Is there an issue? Battery only a few months old. Thanks.

[@HighTechBatterySolutionsInc]

I ran your question by NOCO, here is their official response: It sounds like the battery may not be holding a good resting voltage, and the charger may be timing out. The maintenance trickle charge should start when the voltage drops below 12.7V, and the LED should be pulsing green. If the battery is not holding a good resting voltage, the charger will timeout and stop applying the charge to prevent overcharging the battery. If the voltage drops below 12.4V the charger will start the full charge over.

[@MapleMarmite]

Thanks for getting back to me - I’ll double check the voltages during the same situation again to see if I can pin point any issues.

[@MarkM-c7h]

Great review, I just got one and wanted to know if you charge your 12v battery and just leave it hooked up does it then work as a trickle charger ??

[@HighTechBatterySolutionsInc]

Yes, once the charger has brought the battery up to fully charged it will then go into its maintenance mode automatically.

[@FreeClimbersNet]

A follow on, as I am using it now on some old agm's: When will you know when charging is completed? I've had one on my noco10 for about 5 hours and the green light just keeps pulsing slowly. When it switches to maintenance mode, does the color ribbon do something differently, essentially telling you when best effort charging is completed?

[@jah6169]

I just received the Genius 10 Charger + Maintainer, I am planning on storing my vehicle (Genesis QV 70) for the winter....Is this the correct Maintainer? Thanks

[@HighTechBatterySolutionsInc]

Yes, the NOCO GENIUS10 can properly maintain the battery in storage without an issue.

[@ericandsharonfritz9553]

Would the 10 be a good 10amp charger for marine deep cycle batteries and if so is it fast charge? Thank you.

[@HighTechBatterySolutionsInc]

The NOOC GENIUS10 unit is solid 10A charger designed for both automotive and deep cycle usage. A fast charge will depend on the capacity of the battery, to find the charge time you take the capacity of the battery and divide it by the output of the charger. The resulting number will be the total time in hours it will take to charge assuming its been fully discharged.

[@islic1]

Nice review thanks! I am a bit new to this and I am using this on a Dutchman RV, being as this is a "smart" device, can I leave it attached and use it like a trickle charger also?

You know, when to turn the self facing mode on whether it's dead or churged. What does it mean when you have a green and red light flashing back-and-forth?

[@johntrenfield8214]

Hi,I’ve just used this device to recharge a new deep cycle marine battery, which I bought a couple of months ago, but haven’t yet put into use. Is it to be expected that it would have run down to less than 25% charged in that time, and how could I tell if I needed to employ the repair mode?Thank you.

[@HighTechBatterySolutionsInc]

Deep cycle batteries will lose a % of their charge every day when sitting idle, so depending on how long it sat it's certainly possible. Since the battery is so new I would not worry about using the repair mode. This is for batteries that are on the older side and heavily sulfated.

[@98XC1]

Is it safe for car electronics and for the unit itself, to leave it ON in a charging mode while working on a car(ignition ON engine OFF type scenario during reprograming or troubleshooting electrical issue) thank you for review.

[@HighTechBatterySolutionsInc]

This is a perfect time to use the dedicated supply mode of the charger - its designed specifically for this scenario.

[@HighTechBatterySolutionsInc]

Yes, this charger will be able to main the batteries on your semi truck - I'm assuming you have either two or four of the standard group 31 series batteries in there.

[@lynnwright7060]

For all you Model A Ford owners who have installed Optima 6V AGM batteries (positive ground), keep this in mind. Most of us have installed a safety electrical switch to isolate the battery when the vehicle is parked, and if you are one of those owners, you MUST turn the safety switch to the on position for this NocoGenius 10 to function. If you leave the switch in the OFF position, the charger will indicate OVERVOLTAGE ERROR LED and you'll never charge your battery.

[@hudson5573]

Great video! QUESTION: Mine just arrived my wife hasn't been driving her car so it sits for a week or more at a time. Should I run the charge mode first, or the repair most first?

[@HighTechBatterySolutionsInc]

I recommend running the standard charge mode on the unit, I only recommend hitting the repair mode if your having any starting issues or capacity issues with the battery.

[@sc010031]

hi, I just purchased this. Can you tell me how long the device needs to be plugged in to fully charge it? How will I know? Thank you I know it is a basic question.

[@HighTechBatterySolutionsInc]

Just to clarify, this is a AC operated battery charger. It does not have an internal battery that can be charged up, it must be plugged into an AC outlet in order to function.

[@artberte8529]

What setting would you use if your leaving a car sitting for 4 month? It has a 12 volt battery in it. So red on red black on black right? Should it be plugged in prior to connecting it to the terminals? We don't have the box left it 2000 miles away...... How do you hold it to the wall?

[@HighTechBatterySolutionsInc]

Yes, red to red and black to black. If you have it hooked up wrong the charger will error out and let you know. I recommend connecting the charger to the battery first and then plugging it, but thats not a necessity - any order will work. The charge mode you want to select will depend on what type of battery you have in the car. If its a standard flooded battery then your going to leave it on the 12V mode. If its a newer AGM series battery then your going to leave it on the AGM setting. In terms of wall mounting - the mounting bracket and strap combo are in the box with the charger. If its 2000 miles away then its time for you to get creative if mounting it is a must :).

[@defenderovich1898]

Great review! Will the Noco Genuis10 adjust the charge amperage automatically according to the charged battery characteristics?

[@HighTechBatterySolutionsInc]

The GENIUS10 unit will taper off its bulk charge rate as the battery nears the fully charged point and continue to lessen the charge until the battery is fully charged. Its the last 10% thats considered the finishing charge in which the charger is ramping down from its bulk charge mode.

Hello,I need something that will maintain 14v when I am working on the car for up to 10 minutes at a time with the ignition in stage 1 on. Will this keep my battery at the 14v required. This would be required for coding or flashing the ecu purposes

[@HighTechBatterySolutionsInc]

We use the supply mode on the GENIUS10 unit to keep power to vehicles while we do a battery change out. We find that it maintains a steady 13.65V on the voltage for us and does not fluctuate. It can handle a 5A load on it, I'm not sure what stage 1 ignition would draw to give you confirmation.

[@etcetc6307]

Thanks for all the explanations. Can repair mode be used on an AGM battery? I keep getting Battery Not Hold Charge error. Should I try the Repair mode? Thx.

[@HighTechBatterySolutionsInc]

If you keep getting the No Hold Charge error then you have nothing to lose by trying the repair mode. If it errors out in the repair mode then your looking at more than just capacity loss as an issue with the battery. I always recommend the repair mode be used only necessary with AGM series batteries. The reason being is that the repair mode can cause gassing in the battery and as you know with a sealed AGM series - you can't replace that lost water.

[@dfestoon1]

Just bought one and the connectors on the charging leads won’t connect together. NOCO says send it back to the supplier or take pictures of the connector and send to them. Either way it’s unusable, so be prepared to purchase one with something defective and having to send it back. Don’t expect to buy it and then use it, unless you’re willing to splice the wires and void your warranty. What else might go wrong with this product along with bad connectors ?

[@darylchenoweth9057]

Haven’t made my purchase yet. Perhaps it’s clear to everyone but me but I have a question related to the Genius 10. When charging a 12 V battery do I always have to select “repair” mode when I start charging (or does routine charging begin after simply selecting “type” of battery)? Is “repair” mode ONLY selected when reconditioning a battery is necessary?

[@HighTechBatterySolutionsInc]

You would only select repair mode if you know the battery is sulfated. When you're going to charge a 12V battery you would start by selecting the proper battery type - you do not have to select repair mode to begin charging any battery.

Will this maintain the batteries on a semi truck?

[@mattt5276]

When do you decide to use repair mode? Wait until the battery gives you problems?

[@HighTechBatterySolutionsInc]

Here at the shop we only use the repair mode if there's a problem with the battery. If a customer brings in a battery that was left sitting discharged for a period of time, if a battery is having trouble retaining voltage, or if we see a reduced capacity in a battery that doesn't match up with its age and use.

[@Gum05]

How do you know when to enter the repair mode? Do you try this when nothing else works? Is this where you do the battery desulfation at?

[@HighTechBatterySolutionsInc]

We use repair mode for batteries that are having issues maintaining a fully charged state (voltage drop with no draw), low CCA output, or capacity loss. I will typically engage the repair mode on a battery experiencing one of the above after completing a charge cycle on the charger. The repair mode will work on desulfation of the battery.

Let me start by saying I'm trying to learn a bit here. What would have happened if you stayed in 6V? As for the repair mode, is there an indicator on the NOCO that tells you repair is needed or do you just set it and see if it goes into repair mode?

[@HighTechBatterySolutionsInc]

If you were to put the charger in the 6V mode on a 12V battery it would error out letting you know that the voltage selected is incorrect. As for the repair mode there is no indicator on the charger that says its time to hit the repair mode. You will have to make that call based on the situation - for example if the battery was sitting discharged for a long period of time, or if you notice an overall lack in capacity of the battery and want to try to recover it.

My son give me the Noco Genius 10. I have a 2019 Camaro SS. Planning to store it for the winter months, at least three to four months. How do I use this charger to keep my battery charged? Great video, by the way.

[@slickrickdarula9483]

Did you end up getting this charger just wondering because I have a 2016 SS Camaro that I store for the Winter I had a CTech charger but it burned up so I'm looking in to one of these noco's

[@bishopgeorge1333]

Great video, do you have to plug it in an outlet so it will work, the reason why I ask when my RV battery go dead for the winter and when I go out to my storage was the RV is store I don't have any outlet to plug it into to power up.

[@HighTechBatterySolutionsInc]

Yes, you have to plug the charger into the wall in order for it begin charging.

What is a good jump start charger that don't need to be plugged in

[@darrickhummel7650]

A nice review. How do you get the 12V repair function to work? I switch to it and it just blinks red. I’m trying to figure out how to get it to solid red/activate.

[@HighTechBatterySolutionsInc]

The blinking red is what you're looking for, the light will continue to blink red throughout the whole repair process. Once it's completed you will get the solid green LED on the charger.

[@landonwoodruff]

This is the same question I had! The manual said solid red everything else I saw said solid red and mine is just flashing.

[@cheryllinford443]

@@HighTechBatterySolutionsInc how do you know if your battery needs the repair mode if you can get the car to start with the charging mode only with one or two red lights across the bars and it has not reached the green light yet? When I select the Repair mode it just flashes red.

[@HighTechBatterySolutionsInc]

​@@cheryllinford443 We recommend using the repair mode if the battery is not performing as it should, or if it's been left in a discharged state for longer than 30 days. If you accidentally drain your battery and its not been left in a discharged state for 30+ days then we recommend hitting it with the standard charge mode.

[@vincepena6308]

I just bought this, I have in plugged into a wall outlet. How do I know if this charger if fully charged?

[@HighTechBatterySolutionsInc]

The charger itself does not have a battery in it, and will not be able to retain a charge. In order for this charger to function it needs to be plugged into a wall outlet. I just want to be clear that this is not a jump starter -

[@charlesmcgehee3227]

If you are asking how to determine if the battery you are trying to charge is fully charged, just wait for the single solid Green LED to light. If it is lit but pulsing on and off, just wait and leave everything alone. Some batteries can take a couple of days to reach full charge. (Solid Greed LED lit and not blinking) Car batteries need care. They need to be kept charged or damage occurs.

Thanks for answering my last question but I have another one... I have a 2021 Ram 3500 diesel with 2 batteries , Could I use the Genius10 to charge my 2 truck batteries using the rear 7 pin trailer connector in the rear of the truck. It would be easier access for me. I've heard rumors it can be done but I can't find anything on how to go about it. Any suggestion would be very much appreciated.

What should My noco genius 10 read on my multimeter when charging a 12 v lithium battery

[@monacokord]

Hello, I have an SOK 206Ah battery that I've been using for testing/ running my electrical system in my campervan. I have been away for about a week and noticed that my lights wouldn't turn on and that the battery was completely dead (26mV) I only have a conventional 12V 6A charger which I mistakenly tried to use to bring the voltage back up. Will the Noco genius 10 be able to wake up my battery and charge back to normal and which mode should I use?

[@HighTechBatterySolutionsInc]

In all honesty I'm not sure the GENIUS10 would be able to wake up the BMS on the SOK. I recommend reaching out to the company to see what they recommend - I'm sure there is an SOP for this kind of thing they can send to you.

[@theamerican4609]

I left a sine wave inverter on to charge tool batteries on overnight by accident. My one year old battery is completely dead (no sounds). How do I know which mode to put it on, the charging mode or the repair mode? Thanks.

[@HighTechBatterySolutionsInc]

Try the charge mode first, the battery is pretty new so it should bounce back without an issue.

[@montana9703]

this went right over my head...so, quick question. I opened the box, plugged it in for three days. Nothing changed on the lights to indicate it was full. I suppose I'm old school. I need to put a charge on my car that has been sitting for a few months...someone told me to put it on a slow charge for a few days to get it back working as the battery is only a yr old. Help please....

[@HighTechBatterySolutionsInc]

Did you hit the mode button to engage the charger?

[@maf337]

Does the GENIUS10 charger save its battery settings (battery type, voltage level, etc) when you unplug it from AC power? In other words, so I need to select my battery type and 12v or 6v every time I plug it into AC? I am looking into purchasing this charger to keep in a camper van for the house battery. But I will not always be on shore power, so it would nice to not have to change settings every time I hook up shore power. Thanks, and great video!

[@HighTechBatterySolutionsInc]

The charger will remember the setting it was last on so you do not have to physically select it every time you unplug the charger.

[@maf337]

High-Tech Battery Solutions, Inc Thanks for the quick response and information! One other question. Let’s say I have this connected to a house battery in my camper van, and I am using a few power consumers in the van that run off of that same house battery. If I am connected to shore power (and thus the GENIUS10 charger is also powered on), do you know if the charger will help supply a steady DC current to maintain the house battery level? (assuming that my current draw off of the battery is less than the chargers 10amp capacity)

[@HighTechBatterySolutionsInc]

​@@maf337 To my knowledge the charger will supply a steady current regardless of the conditions affecting the battery. The only thing I can think of is that you will run the risk of over-charging your batteries should this setting be left on for long periods of time and you have no draw on your batteries. Since this is a straight power supply mode there is no feedback loop between the battery and charger to let the charger know the battery is topped off.

[@dodgerdawg42]

I have a truck that often will sit for weeks, which setting do I use for trickle charge?

[@HighTechBatterySolutionsInc]

You only need to select the correct chemistry for the battery in your truck. At the end of the charging cycle in each of the modes on the charger it will automatically go into its maintenance mode.

[@cziasai]

Perfect for what I needed. Thanks

[@CameronQuarrels]

Does it have to be plugged in an outlet to charge a battery or work?

[@HighTechBatterySolutionsInc]

Yes, the NOCO GENIUS10 charger does need to be plugged in to function. Keep in mind that this is an AC powered battery charger - its not a jump starter and does not have an internal battery.

[@bappilu]

can the supply mode used to support (maintain 12.5v) a battery while diagnostics/coding is being carried out on a vehicle?

[@HighTechBatterySolutionsInc]

Yes, the supply mode can maintain voltage to a vehicle while diagnostics/coding is taking place.

[@tomcross9967]

Hi thanks for the video could you tell me do I have to disconnect the battery to use repair mode

[@HighTechBatterySolutionsInc]

Good question, I'm not 100% sure on this so I would recommend only using the manual repair mode on batteries that are disconnected from the vehicle. The problem is a lot of the newer cars have computer systems built in that I would assume could be affected by high voltage spikes - better to play it safe than sorry.

[@charlesmcgehee3227]

Before plugging in the A.C. plug, put on the battery clamps. Then plug in the A.C. Put the unit into the Repair mode. The red LED will flash on and off. for around 4 hours and then the unit automatically switches out of the Repair mode. However, if the battery is too badly damaged, the Repair mode will end early. Not all batteries can be "Repaired".

[@globaljob8689]

I have a fiamm batt that have not intensive used at all prior and has been sitting around untouch for 6Years. I’ve recovered to 12v but after using it for a few connections with a dc ac pure Snr wave inverter, it went below 9v. I did not recharge it for a while but when I tried, it was not able to charge up normally. No obvious bloating but now I can’t bring it back to life. Now it reads 0-1v. I’m contemplating to buy NocoG10. Will it able to force it back to 12v even without refreshing it with Epsom salt?

[@HighTechBatterySolutionsInc]

The recondition mode of the GENIUS10 will be able to recover a portion of the capacity of the battery however 6 years untouched is a very long time. If the plates have physically deteriorated then even attempting to refresh the battery would not yield any results as the total active surface area available to produce energy has been permanently reduced.

[@liordadon371]

I have a 2020 Seadoo with a 12v AGM battery and haven't used it for a long time so the battery is dead completely. I tried charging it with my regular charger but approximately 30 min after I disconnected it the percentage dropped from 100% to 70%. Do you think the Genius 10 could fix the battery?

[@HighTechBatterySolutionsInc]

The GENIUS10 recondition / recovery mode will certainly help this battery out. Typically if we see a battery that takes a full charge but is unable to maintain its voltage we will use the recovery mode on the charger which will help the battery retain its fully charged voltage.
