Honestly, this is by far the most intelligent video, I've seen on an intelligent charger. I have now just eyeballed my "deadish" UPS, as I am busy charging my car battery in the background. Thank you for clearing up all my questions. 🙏🏻
Thank you, sir. As a ham, CB & UHF radio operator we always keep backup batteries & inverters in case of emergency. I have a few 3.3, 7 & 12 amp gel cells & some larger lead-acid ones. These are for an emergency & is a whole lot closer with this Russin business now going on. I have this same charger. They work. I recently was given an 85 Ah battery. I topped up this 85Ah sealed leisure battery (I distill my own water) by drilling 6 holes topping it up & resealing it with hot glue so easy to remove & re-top up in the future. I had it on pulse repair overnight & it brought it back. My only test was on a 12-volt kettle that draws about 14 amps & It boiled a full kettle twice so far & close to an hour of 14 amp constant current draw & it's still well over 12 volts, but I will give it some more pulse charging. I have 2 126Ah truck batteries that I have been maintaining on pulse repair in case this Russian war business goes nova & the UK loses its power grid with conventional or EMP weapons. UK power grid is very fragile. God help us if that happened all nuclear facilities could not be maintained & would explode. If there is a god that is.
Good to always come across someone who has also witnessed the good this charger can do. Definitely share your concerns on the current war. Hope it resolves without getting to a climax! Do keep those batteries charged!
THANK YOU SO MUCH for this awesome and straightforward video!! 💯❤To me, this is the BEST among many videos about the Foxsur device!!! 👋👋KEEP UP YOUR GOOD WORK!! 👍👍
Big Thanks from the UK...I have one of these chargers but I didn't understand the instruction leaflet as it is in broken english translation...so very grateful that you made this video...Really informative...Big Thanks
Good review, looks like the Foxsur charger uses 16 volt pulses to desulfate a battery like the Noco Genius 5 and 10, and the CTEK chargers in repair mode. I used my Pulsetech PowerPulse on my other BMW Duralast Gold battery that is 7 years old and that I let sit disconnected for a year, and it was at 11.2 volts, I tried charging it with my friends Exide 6 amp automatic charger for 14 hours and battery voltage was at 13.1 volts, yet it would not start my other car. I put the PowerPulse on it along with a 1 amp Schumacher manual battery charger for 72 hours, and left the desulfator on it for a week and it started my car right up. My point is desulfation can take up to 30 days depending on how sulfated your battery is. Pulsetech claims that their patented frequency they use gently desulfates a battery and can extend it's life up to three times. ua-cam.com/video/2qTzKwujoW8/v-deo.html
Thanks for sharing this. I've only tried reviving batteries using no more than 24hrs. I'll put the Foxsur to the test with these extended pulse intervals and see.
Work well on my batteries. Depend on CCA and SOH. Larger CCA tooks longer to repair.. Lower SOH tooks longer time to repair.. My 380 CCA tooks about 4 hrs to brought from 90% to 100 % SOH. My 720 CCA batrery tooks 32 hrs to bring 86% to 100 %SOH. In principle need to charge full and wait for 1-2 hrs. If it still have 12. 6 volts mean you still can desulphate. If say 10v or lower means one cell already defect due to shortage or etc. if it could not maintain charge on 12.6 with high SOH means you by mistake overfill the electrolyte level. Have one battery that i charge from SOH 47% to 100% with 300CCA. It tooks about 11 days...
Yep.. My car was repair in workshop for a month (overhaul) and in the painting worshop for another 3 weeks..and unfortunely with pandemic the car rarely drove. So the SOH dropped to 47%. My car battery is a chinesse battery.. Worth to try.. yes 11 days it just back to SOH 100%.. the battery was 2 years old by the way. For another two cars battery that i got are japanese Yuasa battery.. not much problem to desulphate I have 3 cars so really need tools to simply maintain the batteries
Repair mode also charges the battery so it should be charged. Even if in doubt since it can also be used as a trickle charger it shouldn't hurt if you switch to AGM charging.
Will it only function if it's connected to the battery of the car? I connected to electricity and says off. Only when I connect to electricity and car does something.
Not exactly - this device doesn't detect internal temperature of the battery but internal temperature of itself (temp. sensor is located in the charger and measures temp. of cooling air). If you use it in cool environment it will detect cool air. This small battery should be charged in repair mode (1,5-2A pulses). 4-5A in normal mode it's too much for small batteries. The charger is great, because in repair mode it makes the electrolite density @ 1,28g/cm3 During charging the battery should be disconnected from electrical system - charger gives up to 15,5V, and that may be too much for electronics.
hi can I leave this connected to my bike during the summer because I do not use my bike a lot and does it protect a drop of power in the battery and charger cheers John
The manual states that once charged it may be disconnected or left in place since it features overcharge protection and will only provide trickle current.
12v 20ah tubular solar battery isse charge ho sakta he kya sir.. daily basis se battary charge karke converter use karke room me light aur fan use karna chahta hun..sp daily ehi charger se charge karne se koi dikkat hoga kya.
Not at all. You can charge the battery in the car without disconnecting. Just take note of the connections if charging in car. This would depend on whether the car is positively or negatively earthed just as covered in the video.
Can I ask a stupid question please ? I just bought one and I am wondering whether I need to actually charge the charger before attaching it to the car battery. I got confused cause of the battery level indication on the screen, that is why I am asking.
Thanks for the detailed review.I would like to know if it is safe to just charge ( not repair) while battery connected to car terminals.Can it damage ECU etc..?Thanks
I don't understand how these things work exactly. In order to charge a car battery does it have to be connected to wall socket in order to work? Thanks.
Yes. There's also specific sequence for charging the battery in or out of the car. E.g. You should only use the charge function when charging in-vehicle, the repair function must not be used.
Okay nice! I was searching for someone who tells me that the pulse function is charging the battery as well. I had a complete empty battery with 12V and 56Ah. But: After 3:30 hours with pulse charge it says 100% after switching to normal charge function. Is this possible?
It depends on the voltage it started charging at, but I would say 3:30mins sounds a short for a 56AH battery. Mind you, even after showing full, it is recommended to leave it charging for 1-2hrs
@@DIYAutoworksNG Thank You! I startet my engine many times till the battery was almost complete empty. Only interior lighting was functioning in the end. I will try to charge it 2 hours longer, maybe my engine will start:))
Lol. Sounds like you are trying to test the charger. If you have a battery tester, you could test the battery after charging to get a true sense of its state of charge and state of health.
@@DIYAutoworksNG No, I am not testing the charger for fun. I have troubles cause my engine is not starting. So I must charge my battery. But I can now say that the FOXSUR Pulse Charger is able to charge my battery to run the starter on my car many times. I was hoping maybe my engine starts if I use the pulse function because I am not sure if my battery is too old despite of 12,6V. Maybe I must try pulse function 2 weeks. Maybe I will buy a battery tester if I will run the pulse longer.
can i use for charge my 12v 20ah tubular luminous battary daily. and use converter for home led and fan use. is there any issue if it use regularly.??? pls clarify
Im just using this charging today and i notice bubble coming out from the battery but some don't bubble. The one which don't bubble mean is dead? Could this charger revive it back? Done 8 -10 hours repair and still no bubble coming out from few reservoirs
Bubbles are hydrogen gas. Remember to always charge in a ventilated area. Gassing usually occurs when the battery has reached 80% capacity. Being revived depends on the state of the battery. A battery tester will determine the state of health. If the other battery is a wet cell battery be sure it has enough electrolyte.
Difficult to say without examining the battery in person. Could be one of 2 things, battery has not reached 80% charge state or its not taking a charge. One limitation of this charger is that it cannot revive batteries that are so badly depleted e.g. Less than 8.5volts. What voltage was the battery before you started charging? What's the battery size?
@@DIYAutoworksNG @Piyke DIYAutoworksNG Battery has been repaired for 24 hours and it has to reach 80% by that duration. Other have already start bubbling accept another 3 more not bubbling at all. The battery start at 11.3v before starting charging and the capacity is about 40ah
Pulse repair for this particular charger can last between 8 - 24hrs. That said, one limitation of this particular model is that I haven't seen it switch over to normal charging after pulse repair. I just count the number of hours and switch over manually. Note that the battery charges too during pulse repair.
@@DIYAutoworksNG ok i got it,but what if more than 24hrs charging under repair mode is it the battery having a problem?and i need to put this to a trash?
Not necessarily. I believe its a defect in the charger. Just press the repair button again so that it goes to normal charging. After it shows 'FUL' leave it charging for 1 more hour
@@DIYAutoworksNG ok, sometimes i think of its necessarily to buy a new foxsur charger just bcoz of this pulse repair mode took to much time,by the way thank you
A battery with good cells should be expected to last as long as its built to. Except if there are parasitic drains that keep depleting the charge. Does must be found and resolved. A battery I recharged about 3 years ago is still working. It just boils down to whether the cells are good or not. Damaged cells will either not take a charge or not hold it well.
I have the same charger, I put it to the test on six bad batteries, it did absolutely nothing for them , all six were not improved at all in any way, my wallet was lighter than it was before I bought this charger, the only thing it did accomplish
@@DIYAutoworksNG It cannot restore anything with that "Pulse repair" mode, it will recharge at a abysmal low amp rate on a low battery, but the pulse repair of a bad battery is pure nonsense, I have a thirty year old charger that charges better than this waste of money,
Rather unfortunate. You did get your money back though? Same seller? I haven't have no-delivery issues with Aliexpress. Want to try a different seller on Aliexpress or Amazon?

Not at all. You can charge the battery in the car without disconnecting. Just take note of the connections if charging in car. This would depend on whether the car is positively or negatively earthed just as covered in the video.
I’m trying this now on my 80 ah battery that was showing 10.8 volts, I’m hoping it fixes my battery as it was expensive
Best of luck!
How does the charger work in battery recovery mode? What is the maximum voltage applied to the battery in this mode ?
You mean repair mode? I am not sure of the maximum voltage applied. It sends pulses of voltage to the battery.
Can I ask a stupid question please ? I just bought one and I am wondering whether I need to actually charge the charger before attaching it to the car battery. I got confused cause of the battery level indication on the screen, that is why I am asking.
No it doesn't need to be charged. It only works with AC power from a wall outlet.
Thanks for the detailed review.I would like to know if it is safe to just charge ( not repair) while battery connected to car terminals.Can it damage ECU etc..?Thanks
Thanks for the compliment, You can charge, but not repair while connected to the battery terminals.
If left connected will this smart charger work as a maintainer?
Yes. The manual says so
can i make additional charge to my battery even if it can still start my car? thanks
Yes, you can. In fact it's good practice to externally charge a car battery that goes below 12.5v. Keeping it fully charged keeps sulfation away.
