- For the most people, they would throw a dead car battery off when those thought so; However in the most cases, a dead car battery can be recharged at home successfully and save $$$. This video will show you how to do that step by step.
Hi friend what are the amperage for the high and low settings
Thanks for your question and is good one. It depends on that battery charged condition, although from the charger's point of view: Hi should be almost as twice as Lo but in practical and moderate condition, the charger in Lo position - say: 5A has been indicated ie. if you change to Hi position right away, you should respect to get 8A or so and proximate. The poorer battery is, the higher amperage.
@@diymade2175 thank you for your quick response and helpful information
Hi there, thanks for the video. I am going to give this a try tomorrow. I like that you just get to the point without a bunch of nonsense and chatter. Well done and thanks. ;-)
Thanks & hope you enjoy the experience!
Did it work
@@718stix My battery charger only has 55 A Engine Start, not nearly the 200 A they used here. No, it did not work. I did not see the logic of buying a higher rated charger at this time, when I had to get my car going and money was short. I did buy another battery, but did not return my old battery. I am determined to try again and make this work! I will either borrow a stronger charger or maybe do more cycles with the lower amperage charger. Does anyone know if the lower amps with more cycles will work?
@@chickiejackson1379 try sulfuric acid and distilled water then low charge for 48 hrs
of all the battery videos i have seeing i never see anyone clean the top of the battery except this one and some was really dirty, but this guy don't talk . and i did not know Australia makes batteries
Thanks Mate, certainly do !
Only century deep cycle and starting flooded type are Thats it
Its said, "Positive on First, Off Last". From friends retired from building Die-Hards & Interstate, so they have had plenty of experience.
Thanks ! That's the way to go.
Not trying too tell you what too do! Just thought I'd mention! But it something they follow! Positive on First, Off Last!
@ Tim Barnett When I was taking Residential Electric course in the college, the teacher said the positive is like the captain of the ship- FIRST ON, LAST OFF. That’s some 40 odd years ago, but I remembered all those years…
I was going to mention that! It’s also the quickest way to if someone is noob or actually knows what they are doing.
Personally I've found that adding just distilled H2O, to the dry cells, isn't enough. You MUST add some sulphuric acid. It's only by adding H2SO4 that you'll see a rise in the voltage, e.g. 12V. Otherwise several cells just will not 'wake up', and you'll end up with 8 or 10V.
Thanks for your comment. You did well and good effort ! I must say: The way of restoring a dead car battery depends on "the condition of that battery at that time". The way of recharging dead battery in the video has showed: The one of the most successful cases, BY FIRST ATTEMPTED and fixed battery's problems in the most cases. You have to be very careful about filling acid (some one calls it as "battery Boosta") into battery's cells, sometimes damaging battery may occur although these cases have not been many.
Best to check each cell first with battery hydrometer.
Well done, good point and that is one of ways !
What kind of suphuric acid is recommend to put in the battery
@@efrensoto7848 You should be able to get 'decent' sulphuric acid from a car parts store, home depot, etc. I can't honestly make any recommendations, brand-wise.
About to watch your make charger video. Do you have a circuit to add trickle charge function? I have an old arlec that does not do low charge and would like to mod it. it has 6 and 12volt selection only.
Thanks for your interested ! The easiest way to modify the charger you have, depending on what kind of the circuits or components inside charger have. If your charger is a transformer with center tapped secondary & Diodes type, it can be done just add a Switch to have the charger modified for low and high charging. Watch video "ruclips.net/video/unl48S3bOpw/видео.html" for reference. However if a transformer without center tapped secondary & diodes type, you can add a Switch and a DC to DC Step Up Boost Converter (the Boost Converter is the voltage adjustable as you wish: output 13 - 16 V ie.) to have it done, of course this modification will be a bit more complicated unfortunately I do not have a video to offer regarding this. Good luck !
@@diymade2175 Video link didn't work. can you check link please.
@@blurtmenow You are right but I do not know why it does not work. Anyway, the name of the video is: "How to Make a DIY 12V & 20A Car Battery Charger"? from my channel on RUclips. Sorry for the inconvenience!
Why do so many RUclips channel hosts assume that we all have an IQ of 5? The fact that many of them keep pointing at parts tells me that they must think that we are all stupid. That makes me think that they are stupid.
Total BS. it's a different battery at the end of the video. look at the stickers
yep, it is. i didnt notice till i read you comment. cheers
Haha it definitely works. I do this every couple years on my batteries.
I think this battery was in good condition before the video. 9 volts does not mean it’s bad and not accepting charge it was just flattened before the video then he charged it up. I have tried this method in the past and it does work on some batteries but if it’s severely sulfated this doesn’t work you be there all day. You need higher amps to de sulfate and recondition battery.
And then you take the risk the risk of an exploding battery! I tried 70 A and it went really hot fast and exploded after some times! But my battery showed only between 0 and 1,8 V so they were in worse condition...
@@64TommyG Ive charged a completely flat battery with only a 7A battery charger and in 30 mins it was hot and the casing began to swell. If I had left it no doubt it would of exploded. May have been a shorted cell I don’t really know. Using 100amps would have been a disaster. You must know the condition of the battery before doing so and don’t hook it up and just walk away keep an eye on the battery it will get hot before it explodes.
@@derekmartin8498 Of course the problem was that I did stand and watched it and I don't know what happened but it banged and then it was acid everywhere luckily I wear glasses and did rinse off the car and the surrounding areas before I did wash off my self! In school, I tried every acid and basic on myself and nothing ever felt in other than the eyes and the nose but I don't recommend anybody to do the same because some sorts are poisoning...
@@64TommyG goes to show how dangerous batteries can be. Care must be taken, glad you are ok 👍
@@derekmartin8498 Tank you so much! But as I said if someone should get in an accident it better be me because acid doesn't matter as long my eyes are protected and electricity can I handle upp to 400 V without any problem, it gives me some energy in fact but whit the age I better stop checking if the current is on with my fingers... I've learned that up to a second can you survive if your heart hasn't any problems, so broken cables are dangerous because you cant loose your hand when the muscles are working at 50 Hz, I don't know if it is any difference with your 60 Hz? Nice to talk with you!
What liquid did you pour in to the battery?
It was distilled water !
I have the same battery! I'm going to try this when I get back home.
Why did you leave the cell caps open while charging?
In the most cases, the acid fluid inside battery will be bobbled during recharging process which means the pressure building up each cell especially during Hi charging, so keeping cell's caps open to release that pressure and at the same time to check the fluid level in side each cell. Thanks for your interested! 👍
No explanation why this guy doesn’t talk he waste my time
You've got me & thanks 😐💪👍
Add some script ! What's the whole point of ur effort (and our time)
Thanks for U comment. Yes, script have been there, they may not be showed on some mobile device but surely on computers. Have a nice day!
The battery still holds power after overnight. Thanks
Would it be safe to wear gloves
Good 👍
@@diymade2175 Why did you leave the cell caps open while charging?
Are you planning on saying anything on your videos or just have us listen to car sounds and weird space music?
Thanks for the comment ! you've the choices Mate, such as this video has no words spoken, some had and the other ones have words & music as well.
These are now maintenance free
Yes you are right, there are more maintenance free batteries now days but the batteries are the similar to the one in the video showed can still be found.
No welder needed
Thanks for your comment ! The way recharged a battery showed in the video has been proved: It is a very practical and fixed the most dead batterys in the most case.
@@diymade2175 you're welcome and thank you. Do you think my 10amp charger could do it?
@ Okayman Thanks again. Nothing wrong with your best effort, you can try and good luck !
@@oodles86 check the comment i just posted or look for your self before 8.06 time the battery is different from after this time look at do not tilt sticker handle for scratches and the bar code sticker
@@diymade2175 it worked! So far at least. I repaired two this week. Thanks again 👍
Different battery. Check the numbers on the stickers. Hoax
Total BS. Who knows if the battery was taking a charge before adding whatever
Look Mate, the video was showed to the viewers: One of the practical ways to recharge (restore) dead car battery. Why don't try yourself instead of sitting there to use your own imagination !
This is 100% FAKE !! He is using TWO different batteries! The DEAD battery is 540CCA (pay attention it has WHITE sticker "Do Not Tilt" at 1min 15sec). SECOND battery that is shown as 'charged' 12.93Volts (at 9m4s) is 660CCA and had ORANGE sticker with 'recycle' symbol on it (8min13sec). Check what I wrote by watching this clip (from 8min 3sec to 8min 7sec) and you will see it's a DIFFERENT battery !!!! 100% FAKE !! 100% FAKE !! 100% FAKE !! 100% FAKE !!
