Thank you for your video. I did follow most of your advice and I successfully repair my friend's 3 years old car battery. However I did wait for 13 hours till the Dead battery to 100% Fully charged (Solid Green light), then I set it to Repair Mode. It only took me 6.5 hours to complete Repair mode on my friend's car battery.
By the way, I have seen 5 demo videos about using this NOCO charger in RUclips. Yours is the real down to earth honest video.
Thanks for sticking with it and the great explanation 👍
I had a 3yr old 840CCA Deep Cycle Marine Battery that had been sitting for 2years and was at 5v before I started. Took 1 day to charge and about 1 week on repair mode but it's back. Impressive little charger that's already paid for itself. Thanks for the video! I never would of had the patients to let it do its thing otherwise.
Many thanks for the demo! The test using the hydrometer measurement is quite convincing 8-) it has been a long time I hear anybody says "menisque", since highschool doing chemistry lab!
My first time having to repair and charge a battery, I remember that it also took almost 4 days. But that has been 6 months now and I have not had any problem with my 5 year old original model yellow Optima battery. At first, I was angry and thought my NOCO Genius battery charger was defective. But no, it did it’s job, just took longer than I thought it should.
Thanks for this, I’ve got the same unit and judging by your video I gave up on it too soon. Cheers man
I gave up on mine to soon, you just saved me £200 and prevented me driving my camper-van off a cliff after a coolant leak turned my van into a steamed baked sauna destroying lots of electrics. Thank you kind sir.
Not sure these types of hydrometers are even sold anymore. Apart from Walter White not many people could even uses or read them today. This video includes the most scientific and concise tests I've ever seen on this topic. I've been in the 'recovery' mode now for 36 hours now, I think I'll let it ride, thanks for the video.
Yeah Mr. White! Yeah science!
:)
thank you
Amazon has a variety of hydrometers at about $10
lol @ walter white
Thanks for the nice review. Great that you showed the gravity check, what many people don't even think of. With Noco it's very 'commercial' on RUclips - a lot of talking, repeating marketing crap but not really showing what it does.
You showed the main test - gravity :)
What I miss and would love to see in some supplement (for now just a comment maybe) is how the voltage and amps look along the way. I also tested this NOCO (still am not sure if it was fully okay, as it's not what I'm used to after testing several chargers) and found that it works very strange. It just reaches the target voltage, but won't hold it for any longer. Other brands usually reach the 14,4 (or higher, depending on the mode) and hold it for approx. 2 hours then go to float of 13,x V. The G7200 I used reached 14,4 V and in the same second it stopped charging - voltage back to 12,9 V and it just aimed to keep it. Didn't float, holding 13,6 - 13,8 V as the Swedish competitor for instance does.
My unit also went crazy in re-cycling from 25% to 100% within 2-3 minutes (tests done only on good, well charged batteries, so didn't have a chance to test it really charging anything). Still I didn't like the way it works, as I have the impression that in 'Norm' mode it simply stops way too early, or the unit I had tried is somehow faulty :) Especially since after reaching 100% it runs in circles - back from 25% to 100%, all happening in less than 3 minutes (voltage holds, doesn't get below 12,8 - 12,9 V, when this charger re-starts from the 25% LED and tops to solid 100% LED about a minute later).
Anyways I'd love to see your video showing a multimeter connected all the time and not just before / after. Thanks again!
Thanks much, it's been an excellent charger
Thanks for the video. I did not understand everything as Russian. but with the translator everything is OK, now I have a good device too.
Ive been up in thew air about getting one of these.
Your review swayed me. Just got one off ebay.
Thanks, that's were I got mine also. It's a great charger and maintainer.
Is it a gel cell or lead acid?
Thanks for the video. I’ve owned the G3500 for over a year now and I’ve been very happy with it. I’m sure that larger model is nice. I wouldn’t hesitate to recommend this G3500 to someone that may not need the G7200 for the higher output or 24V batteries.
I’ve used the G3500 to charge/repair all four of our vehicles and I’ve used it for trickle charge on my car when it was out of service for a few months. Also, the G3500 will charge the smaller 6V batteries which I don’t think the G7200 can.
Thanks again.
Mine just took 4hours to repair im so happy and ill try to fish today! :))
I can say this thing works as advertised for the repair mode, although its important to charge your battery's up as much as you can before putting into repair mode, I wasn't able to get the full 100% either before the repair mode but the repair still worked well for 2 different batteries that I thought were done and they are back in business. I found mine for about 85 bucks a few years ago but even at the 100 dollar price it does pay for itself by keeping your batteries in business. Good Sh&t Man
Really good review! Thank you!
Very welcome!
@@MarionBlair very good review indeed and thanks again.
highly recommend this purchase!
Thank you very much for this video.
I just bought a G23000 and was wondering what was going on.
I have 2-6 volts for my rv.
I first start by using the charge mode and after 24 hours it was still pulsating on the 100% mark.
So I switched to repair mode and after 12 hours I end-up with a red repair mode flashing and the 100% one pulsating.
There is no explanation in the instructions about this so I was really wondering what was going on.
This is when I though about going on Google and do some rechearch and here you are enlightening me on the subject.
So I guess I would be patient and see how many days it will take in my case.
Again: thank you very much!
Same here ... top notch vid, many thanks.
TIP:
Best way to charge Ca\Ca Liquid Acid baterries using G7200 is: 1: Use AGM+ mode to charging and next repair mode. And ignore that 25-100% LEDs. They are not working corectly. Use multimeter to check if charger is still working(voltage measurement). The density of the electrolyte is possible to achive only when final charging voltage is ~16V. In standard mode the charger does not reach voltage like this. I have one of that NOCOs. You should start charging with higher current and lower voltage and finish with high voltage and low current. Default "normal" 12V charging mode is too safe for the battery and not achive 16V in last phase of charging. And repair mode cannot be use separately. Is always a last step and can be used only when battery was earlier fully charched.
TheKrisu091
Hi. So you're saying to use AGM mode so that the noco will end its charge mode on 16v - like an equalization charge? And then to switch over to the 12v repair?
I understand why the battery needs to get to 16v, but I don't see why that would improve the repair function since it only uses voltages of 13-14v.
And are you talking about for flooded lead acid batteries? I don't know what ca/ca is
@@marcusgardner7640 Misunderstanding. Repair mode delivers the highest voltage ~16V. Normal charching is like 13-13,5V next 14V and finally 15V for a short time. AGM+ Constantly 15-15,5V and Repair mode have almoust constant 16V 1,5A(Max 16,15V). I suggest to use all that 3 modes when battery is almoust empty. If we have good baterry with 70-80% of capacity and we only want to charge it to 100% use only AGM+ and next repair mode.
Ca/Ca is one of the types of modern liquid Acid Batteries. That means that both +/- cell plates are made with use of calcium. In some older constructions is not good to charche with high voltage like 16V and this is why i'm talking about that. Most of modern batteries are Ca\Ca but you must be sure. You don't want to charche old Sb\Sb batteries with voltage like 16V.
Max Voltages:
Sb\Sb Batteries: 14,5V
Sb\Ca Batteries: 16,4V
Ca\Ca Batteries: 16,25V
Noco can deliver max 16-16,15V in Repair mode.
I'm talking about AGM+ mode. Not standard AGM\Cold mode. That's difference.
If u have NOCO instruction you can find theere all charging modes description including max voltages etc.
PS
I have found one for you ;)
web.bootman.nl/manuals/28-g7200_manual.pdf
@@TheKrisu091 Thanks for the reply. After researching it looks like my battery is of the Sb (antimony) type because it is a deep cycle, not a starting battery (which use calcium.) Unfortunately, it looks like I can't use your tip. My battery is a group 27 EV flooded marine battery (non-sealed) for solar application.
From watching the voltage on repair mode it looks like it stays only in 13-14v, is that because it just goes to 16V very quickly (in the pulse) - too fast to show up on my multimeter?
Personally, I would dump everything in the battery into a plastic container. Fill it up with baking soda diluted in distilled water, and dump it upside down again (repeat a few times). There are a lot of lead particles accumulating at the bottom, causing short circuits weakening the cells and it's a good idea to get them out first. Then I would fill it up with new battery acid. Should be almost good as new. If you don't have a supplier of battery acid, just filter the old solution you saved in the plastic container earlier (an old cotton tshirt will do), mix a tablespoon of epson salt, and pour it back in the battery. Then recharge the battery.
This review is off the hook. A+ love it and its scientific quality. However, I own several infrequently driven antique cars and trucks, given this video's diagnostic effort level needed just buy a new battery then move on, especially if you need to use a "recovery" mode. I rotate a 6v and another 12v Battery Tender to each of my cars once a month. If there is no parasitic draw on the battery my "update" only takes a few hours. I get 6+ years of life on all batteries of any brand, no fancy charger needed to maintain a good battery.
Thanks, good feedback.
If you don't drive them why not just use a single battery on the vehicle you are driving (takes 5min to swap a battery) and an extra to keep on the tender?
Repair mode does work, but you need to run it many times. I was able to get an 800CCA battery that had sulfated to 500CCA back to 680CCA, but had to run the repair mode twice daily for a few weeks.
I actually bought 2 of the Noco Genius G1100 series & installed the eyelet connectors on both drivers side & passenger side batteries. (For easy/Fast connection)
When I know I’m going to be parking the Ram for a few days I connect both trickle chargers up at the same time. Seems the drivers side battery always takes a few hours longer to reach its full charge!
If this will help prolong the life of my batteries a yr it will prove to be a worthy investment.
Yes, I agree, I think it will really help. I was amazed at how fast the batteries draw down when the truck is off.
Hi. Nice review. I read below Robin's comment to leave it on until it returns to standby. That's useful to know. Can you please tell me the lamps you saw/see at the start of the process? Mine is flashing just the repair light about twice as fast as yours in the video and no charging lights at all. Is this normal? First time use for this function and don't want to leave it for days if something's not right. Thank you.
Not sure if my reply stuck but anyway, I had a green light in the end and the repair was flashing. That's still possibly an error but I was successful. Not all batteries can be recovered. Heavy sulfation is probably not going to get fixed. I'm not a big fan of repairing batteries but it did work in this instance.
Trying my G3500 on repair mode as soon as the battery charges. It is a Varta C30 12v 54Ah. Will post follow up.
I also have this charger and I have two batteries that do not fully charge them, the last LED always keeps blinking even if the battery has been charging for more than 24 hours... should I use the repair mode? My batteries are closed, does this put the battery at risk of exploding if I put it in repair mode?
I have a ton of batteries... mostly AGM, some normal and I have a number of the NOCO chargers. One of the G4,s.. This one and a G26000. I like the fact that I can charge them all,.. indoors,.. outdoors,.. mix up AGM and normal/Lithium as my cars eat batteries with all the electronics onboard. Also good for motorcycle batteries. Next thing to try is the NOCO jumpbox. Sigh... I don't have an issue!
Noco customer support is excellent also
Also the timing charts is based on a 50% depth of discharge battery. The 4 hour repair is based on a completely charged battery as you’re only supposed to initiate repair mode when it’s fully charged even though that seems counter intuitive to some
Yes agree mine never would fully charged but it still repaired
Marion Blair it will always attempt to repair of you put it in that mode, and as long as there’s a measurable improvement within the parameters it will end without an error
@@Fee.1 yhank
solid green and flashing repair light is not complete keep it going and specific gravity will continue to improve and it will switch to standby mode when complete 7 days for mine
Great, thanks, mine took 3 days and I thought it was excessive but apparently not.
Robin Underwood belated thanks for this information. Instructions say repair mode takes up to 4 hours, but I’m many days into it and repair mode is still pulsing power in.
sooooo ? when the 100% is not flashing but the repair mode are still flashing like ine the video... we need to let him finish again and wait to have only the light power on ??? did i understand well ???
So it does go to standby. I let mine go on an older AGM battery that I thought was toast. As I recall, it took 3 weeks before it considered it done and I noticed walking by one day that the lights had changed. That battery went for years afterward, but I had a spare essentially because I couldn't go 3 weeks with no battery. (Obviously pre Covid and WFH.)
jo caron yes, this is correct... Repair mode will be complete when unit goes back to standby mode (See my other comment above). As per the NOCO URL below, the repair mode is not complete until the charger is back on Standby Mode (other led to the right, not the charging % above).
URL: no.co/support/sulfation-and-battery-repair-mode
QUOTED: "12V Repair can take up to four (4) hours to complete the recovery process and will return to Standby when completed."
The Genius 10 is a work horse...It has saved batteries that others where ready to toss out.. And being a Battery cost $170.00+ today... the $100.00 for it was well spent....Now I leave it on all the time... To keep the battery in top condition at 12.7 volts..
Yes, better than the replacement.
Hi, FYI, I think there are some confusion about when Repair Mode is complete. As per the NOCO URL below, the repair mode is not complete until the charger is back on Standby Mode (other led to the right, not the charging % above). I have a 31 DC battery, and it has been on repair mode for the last 3 days, and the repair led indicator is still flashing red, and the 100% is solid green (and has been) since I did the 1st step (i.e. fully charge the battery first)...
URL: no.co/support/sulfation-and-battery-repair-mode
QUOTED: "12V Repair can take up to four (4) hours to complete the recovery process and will return to Standby when completed."
Yea, Mine took much longer. I think there is a point where you just chunk in the towel and accept the battery is not repairable.
Now I am really confused. Some people seem to have experienced the charger going back to standby mode when repair is done and NOCO support indicated that if a final charge is done during the repair cycle, then the green 100% light comes on and the repair one just keeps on flashing and it never goes to standby like their articles and manuals suggest. So now I don't know if I leave it be or move on to the next battery. (Mine is green with recovery flashing and has been for hours.)
I think the conflict happens when people put it in repair mode before the charging is complete. I have a genius 5, and it took 2+days to complete just charging of a battery that had a voltage of 12.6. It's the last optimization/saturation step that takes the longest. Noco rep said it could take up to 48 hours to complete. So i left it and at the 46 hour mark the pulsing green light changed to solid indicating full charge.
I am wondering if this repair mode could be done with the battery on the car, I am driving one of those Audi with AGM battery placed in the trunk, with auto cut off on gradually consumers (dome lights, "welcome lights" etc...) i just don't want to remove the battery.
And yes, I'll hook it up at the front engine bay, where is ok to jump it, not straight at the battery while is connected.
Your answer would be very helpful. Thanks!
I would disconnect the ground. You could also call Noco as they have great customer service.
Strange thing: At the first initial hookup & charge the drivers side battery was showing a 50% charge & the passenger side was showing a 75% charge!
I guess the drivers side battery takes more of the load.
My Ram is a 2017 with only 957 Miles on her.
I do have future plans on purchasing one of the much larger series Noco Charger for extreme cases of desperation charges (for the other family autos.
Mine did the exact same thing, the drivers side was taking 5 amps, the passenger side taking 2 amps. The batteries are in parallel and when I message the voltage of them, they are identical but my driver's side depletes faster.
I honestly don’t think today’s owners of these Newer Gens Understand all the electronics within these trucks & the constant pull/drain on these batteries! I have practically made them my top priority!
Yea, it shocked me when I started looking at my battery voltage after the truck had been off for a couple of days. It still started fine but it's got to take it's toll on these batteries eventually. Since I started trickle charging I can actually tell it's turning over faster and starting easier so that's a benefit to the starter motor also. Thanks for the info, I sure like this Noco.
Marion Blair & Gump Forrest: You two do realize that using two chargers to charge your dual battery trucks is completely unnecessary, right? You seem to understand that they are wired in parallel. So why are you charging them with two chargers? The chargers are going to fight each other. One charger will charge both batteries as long as they are connected in parallel. Marion Blair, you are correct about the benefit to the starter motor these maintainers provide. I am sure your vehicle is spinning up much faster and easier. These chargers really are a must-have item.
Yea, I don't do that, this is my connection. ruclips.net/video/pzB-N1P1heQ/видео.html
My Noco G26000 only came with the wire attached to the clamps, No extra short eyelet and plug wire for permanent battery mount quick plug ins. Does the repair mode work outdoors in cold weather? Merry Christmas 🎄🕯
I don't think it matters. If it's going to repair it it should work in the cold.
if i have a dead lithium battery , and purchase this noco charger , first do i need to charge the hole battery and then put the "repair" mode or put thevbattery in the repair mode from the get-go ? thanks
Charge it fully, then put in repair.
@@MarionBlair thank you sir !
I would be interested to see a video of you repairing batteries with the Genius10. I have had trouble finding any videos of people using a Genius10 to repair a 12v battery. I recently bought one after much research (plus it went on sale on amazon for $79 this last weekend on Amazon). I have soem 12v batteries that are at or below 1v of charge. I am starting by puting them in charge mode. I have been sorting out how to control them and charge them with this charger. It appears I have been able to get a force charge to activate and bring voltage up to over 1v. And I am now in charge mode on one for a few hours. The 25 percent LED is pulsating. So I believe it is receiving a charge. I will keep an eye on it for several more hours to see if it increases to 50 percent or higher. And hopefully it can get up to 75 percent or 100 percent and then i will put it through a repair charge. I am hoping for the best. Thanks for your videos.. this one and the other one where you showed the Genius10 that NOCO gave you as part of their Warrantee protection.
in repair mode the red light blinks on/off, and the charging indicator goes from 25% to 100%(full green) and stays solid green for a short while, then the charging indicator starts again from 25% to 100% (full green) and this happens over and over. should it remind on solid green indefinitely, while the repair+ red blinking light goes on/off, or what ?
If repaired solid green. May not be repairable.
@@MarionBlair the 100% green light is solid but after about 15seconds, it starts back from 25% to 100%, all while the repair red light is blinking. its been about 20hours since i start the process.
@@evolve2survive324 If the battery has caps, check each cell with a hydrometer and see if they are all the same specific gravity. How old is the battery? Most are not repairable
As per the NOCO URL below, the repair mode is not complete until the charger is back on Standby Mode (other led to the right, not the charging % above). They are only not right about the time it takes to complete the Repair Mode. It can take several days depending on your battery condition and capacity I guess...

Hello, tell me please, is it worth taking this charge? Does it raise the density of the battery? the video seems to almost raise, for the purity of the experiment it was possible to measure the density after several hours of inactivity, I think it will rise again. Generally recommend to buy or not?
Он будет ремонтировать только батарею с умеренным сульфатированием. Но ремонт постоянный. По стоимости это зарядное устройство с высокими технологиями, которое работает со всеми аккумуляторами и даже может использоваться в качестве источника питания.
is it safe to repair agms using this mode? I have a dual battery system agms and now the full charge reads 12.9/12.7 when it used to be 12.9/12.9 just wondering if i can repair the second agm using this feature or if i will hurt them putting into repair from this full charge lvl
Yes, should work with AGM if it's repairable.
I have an optima batt I have never used and it was a decent chunk of change. It must be 3 years old what setting would you reccomend me uss to try and charge it using the 3500 model?
Do you have to disconnect the batt from car to use repair mode? Thanks
Peter, no you don't have to disconnect it. I'd charge it fully on AGM setting since it is a spiral AGM type battery. Charge it fully, then repair mode if it doesn't hold charge. For repair mode, I'd probably disconnect one lead.
The older Optima's are the best ones. I'm hearing the new Optima's aren't as good as they used to be.
Marion Blair Thanks man!
The optima is an AGM so that's what I'd use. Fully charge it, then put it on repair since it's been sitting there, it's probably sulfated
@@MarionBlair Dear Marion, thasks a lot. I have a guestion;. I have exide gel batt. It's capacity 19Ah and I bought it 3 months ago, it's birthday December 2018. And I have noco G1100. My battery is deep decharge. :( And I connect charger to battery, approximately 24h ago. Led indicator show orange (that %75 light) flash at the moment.

Hi There, I have a 2010 Volvo XC60 with a 8 month old new battery I got at Costco and without starting my Volvo for 2 days I can not start my Volvo. I have to keep on boosting it to get it going. Thing is if i go to 3 days my battery goes dead. Now I have to use another car battery to start my Volvo. My question is can I use that G7200 or the G3500 while the battery is still in the Volvo all hooked up ? Or do I have to remove the terminals ?
No you can leave it on there no problem
Assuming you got a good battery, there's something draining your battery drastically while your car is off.
Marion Blair will this genius be of any help ?
I asked the question on 1/17/2020. on this topic and that's what they answered me today. Message:
I apologize for using a translator. I used Repair Plus mode. Repair lights flash and 25%. this has been going on for two days, but now I was surprised that on the tester, 8.9V.. 7.4A . before that it was 11.6 volts. the electrolyte density is approximately the same 1.17 .. and how much it can stand on charge like that. (battery pb 80a 650en) and I want to ask is this normal 2 days?.did the other battery in this repair + mode charge for about 4 hours? .........Thank you for contacting NOCO support. No worries about using a translator, I am using one as well. 12V Repair Mode will last up to approximately four hours, and then the charger will either go into Standby mode with the orange Power LED lit, or it will automatically enter another charge cycle. If the battery is not completely charged prior to Repair Mode beginning, or if the repaired battery gains capacity that then needs to be charged, or if the charger is unable to reach the 16.5V used by the Repair Mode, then the charger will enter a normal charging cycle and the charge percentage LEDs will begin pulsing. The Repair Mode LED will remain flashing during this time to serve as a reminder that you had run a Repair Mode cycle on the battery, but once the charger shows a solid green 100% LED and the flashing Repair Mode LED, the repair and charge are complete.
If the charger is staying on 25% for a long time, then it is likely that the battery is still sulfated and needs another repair mode cycle. So if you are not seeing results with a single repair mode cycle, more than one cycle may be necessary. Keep in mind that not all batteries are repairable though, and if you are not seeing any improvement in performance with your battery, or if its resting voltage is still lower than it should be (12.8V), I would recommend taking the battery to a local shop for testing. They would be able to let you know if the battery is worth the time to try and repair, or if it should be replaced.
Please let me know if you have any questions.
Kind regards,
Sharla Henderson
Thank you for this information. The repair more is helpful for light desulfation but that's about it.
@@MarionBlair This morning I discovered that the battery is dead. he was 17 years old. 5 he was in the car. then he stood on the alarm in the barn on a charge of 15 volts. 1.2 A. when I got there there was no water I added. it was 6 volts and began to charge noco at first it was not bad 12-13 volts. Then he began to get very hot. probably the plates have already crumbled and the circuit voltage for 2 days has dropped to 8 volts. I sent a message to the technicians noco. At night for 3 days, the charging was turned off, in the morning it was measured 2.6 volts. so if the voltage starts to drop, do not try to charge the charge, tried to maintain life to 7.5A, but the patient was very old. I hope the translator translated correctly
My questions are 1) if we just want to keep the battery maintenance trickle charge mode on do we just leave the cables attached after it's finished charging and the green light is on? And 2) do you think it's ok to run it through the repair mode,( and even perhaps beneficial) , a couple of times? Thanks for your review. 👍
Yes no problem, you can just leave the trickle charger on and it will do fine and also I don't see that it would hurt anything to do a repair.
@@MarionBlair I'm just wondering if it would hurt anything if we ran the repair mode through a few times? I guess maybe that's what you mean in your answer. Thanks again and have a great week!
@@Hundert1 No problem, you can run it until it either repairs the battery or you write it off as a bad battery. thanks.
@@MarionBlair yep, my thinking is to charge then repair then repeat a few times. Any idea if it's ok to draw some power from the battery while we have it connected to the charger on the trickle / maintenance mode ? Thanks
@@Hundert1 I do it, it's a pretty smart charger, it seems to adapt just fine.
I am trying the same process. Yesterday i did the normal charge. Seems battrry stucks in 14,03-14,04V. Now i am trying the AGM. 50% in 14V.
Seems wrong to me.
Could be. It could be the charger pulsing up t 14 then to 0. Mine does that. My G7200 went south on me, Noco sent me a new one. G10 (haven't opened it yet). 5 year warranty.
@@MarionBlair There is no 14-0-14 thing happening at all. Keeps trying to push but batt seems not accepting more.
What does it mean when all top lights are on
Fully charged.
When changing the mode to the repair mode (after the charging mode green light became steady), do we need to unplug the AC power cord? Isn't it always best to first attach the clamps to the battery then plug in the power cord?
Google1 User no you don’t. You toggle over to repair
@@MarionBlair Ok, thanks. How do we decide when to use the repair mode? I mean is it ok to use the repair mode on any battery,? that's just a bit old or maybe we forgot the lights on in the car on a normal battery over night and ran the battery all the way down? Thank you
Google1 User yes that’s a perfect time to try to use it. It’s hit or miss but it works sometimes depending on how Sulfated the battery is.
Also you can measure the voltage. If you have a dead cell forget it there’s no recovering that
@@MarionBlair I see, I just wasn't sure about exactly when it was ok and proper and a good idea to use the repair mode. Is it safest for both the charger device and us humans to first attach the clamps to the battery then plug in the power cord? I'm expecting the G26000 from Amazon today probably. Thanks very much for all your help
What is glass pack. Can be tiped over. Im sure its dead. Sat since November. I should bout a neco
Charge it and see. Yes you can tip it side ways if agm.
The repair mode is good for all type of battery? Also, you said it took 3 days, I am recharging my truck's battery right now, but I do need to drive around, can I stop the repair and re-start later? Do I need to undo the wires at the battery poles? Thank you for this video!
I've used it on both flooded lead-acid and AGM. And yes you can start and stop it. It won't hurt it but it won't finish repairing until you leave it on long enough to do it. If it's repairable leave it on long enough for the green light to come on. Mine took so long because the battery was really in bad shape it probably won't take that long if your battery is in better shape. He can repair it if the battery is sulfated but if there's a dead cell or something like that it's not going to fix it.
@@MarionBlair Thank you for your answer, Very appreciated. It's charging now, was 25%, I am waiting to look at the green light at the end and see if it will need repair.
This charger is awesome, I used it on my two 6 Volt Lifeline Batteries of my travel trailer when the converter blew up while I was living in it to deep the batteries from discharging. Was perfect.

This charger is awesome, I used it on my two 6V Lifeline Batteries of my travel trailer when the converter blew up while I was living in it to keep them charged, saved the couple weeks waiting for the part!
@@MarionBlair I have it n cold AGM/cold it keeps going back to 25% then up, I have not disconnected the battery, is this normal?
@@projet2907 Battery may be not be repairable. You could go to repair and try that.
How often should you repair a battery?
If it's a lead acid, check the electrolyte with a hydrometer several hours after it's been charged. If it doesn't read 1.265 or higher, repair it. Or just do it anytime, it won't hurt it.
Never if you keep it on a maintainer and add water before it gets to the plates
My glass pack bike battery sat all winter. Do i charging. Or do i trickel?
Trickle
Out of curiosity is this battery still in use/still around?
no long replaced it, wasn't really bad however, I just didn't like the exides and used it for a trolling motor and wanted more amp/ hrs so used it for the return.
I love this Charger but I was not that Impressed with the Repair Mode as no matter what battery I use the repair mode on always fails but other than that it will charge batteries that my Schumacher will not.
Yea, I think if the battery is lightly suflated, it'll fix it but anything more than that and not going to happen.
1 agm+ next reaper x2
For what it’s worth you should have left it charging as long as it took to reach 100%. Even days. Repair mode is not designed to be used until it’s fully charged. The normal charging scheme also has a restore function and when it’s taking longer than usual that’s because it’s decided to take the additional steps to actually fix the battery.
You’d have gotten even better results if you had just left it charging until it stayed solid green and only then initiated repair mode.
I believe either way is good. I'm going through the same thing as on this video with the one I just bought.
Actually this excellent charger figure it out by itself that is why the green 100% light come on after being on repair for a while after it sees the battery is not 100%.
My battery is completely dead and when I plug it onto the charger it just stays on stand-by(orange light) and I’ve followed trying to hold the “mode” button and nothing happens. I’m using the G1100
Hi, I have same problem. I did wait one day and I see %25 than %50 and after 36h %75 flash. I wait at the moment. And I did guestion this case to video admin. By the way, I advice, you can wait connect to charger (noco) or you can supply with charger (%20 amperage of it all capacity, with for example 12V DC battery 14.5V DC) sorry my poor English.
You need g3500 and up for repair mode
need to boost the car ... and after this now the noco g7200 will reconize the battery ... i had the same problem
Was it left on repair mode for three days?
Yes. Notice the label/timestamp at 3:14 and 3:36 It says “Repair Mode”. I noticed he didn’t respond yet so just trying to be helpful. 😁
yes
I wonder if this would work on a battery that has sat for 5 years and got taken out because it was bad🤔
I doubt it, probably the point of no return. ha
Is this Forest?
Gump? Yea his brother from a different mother
I hope you did take this rude! It was meant in good fun! Good video BTW thanks!
MINE STOPED WORKING AFTER 2 YEARS.
Mine too. 5 year warranty however
Hi, There is an advice to recondition a battery from very bad shape. In similar way as you did, fully charge the batter with normal or AGM mode. Then instead of using REPAIR mode, use AGM+ mode. It will charge the battery with the higher voltage, about 15.5V. This will increase the gravity to solid green. Look at this experiment (this is in Polish) but if you go thorough the video you will see all the parameters. ruclips.net/video/FD9WHAJd4Lo/видео.html You can also use REPAIR mode after AGM+ but it will not change too much.
So, procedure should look like following (the most effective) Normal/AGM Mode charging until completed -> AGM+ until completed -> REPAIR until completed and results are like: ruclips.net/video/FD9WHAJd4Lo/видео.html
Thanks for this, good information.
Can i use agm mode on a regular lead acid battery??
@@POPKARSCarSales I don't see why not but I wouldn't use the regular lead acid mode on an AGM since AGM required less maintenance voltage and you could possibly cause it to vent
China? I see my Deltran and Ctek chargers are Chinese. Any USA made chargers out there?
Probably not.
3 Days???? so this isnt a good battery charger
I think it's a good battery charger but won't revive a battery that is sulfated significantly. They end up in the battery graveyard at Walmart but one that is borderline like the one I revived in the video may have a chance. I look at the repair feature as nice to have but really wouldn't buy one just for that.
How Much. How Much. How Much. DOES IT COST !
Dicontinued see ruclips.net/video/5sLcbkboP24/видео.html
Avery think almost made in USA is good. Havy duty and long service
Says made in china right on it lol
It’s crap won’t even turn over 2007 HD
