I just found out CTEK recondition mode is actually only to mix the sulfuric acid and water in the battery, as they can separate over time according to their website. This is not needed for AGM batteries and can even damage them because of the high voltages involved in combination with high amperage. Desulfation is always done in step 1. CTEK is not very clear about this in their manuals.
@@hapskie not true i think. i think the longer you have your battery at low voltage the longer the absorbtion phase has to be hence the desulfation happens at the end. at least thats what i learned.
Great content. Two things: 1) Always use PPE, gloves and glasses! 2) You set your battery tester to EN but the rating number used was CCA. A 950 CCA battery would score about 900EN. So your battery was already about 5% better than the results showed.
Bravo, well done. out of reading all kinds of youtube videos this is a top 5. words easy to understand, . thank you. I am looking for solution on AGM battery with crystalization issue.
excellent video, cant find nothing on google on repairing an agm battery, everyone says just get a new one.... a battery should last more than a few years
yea i have 3 agm batteries, i removed those crazy stickers, open it up, used a flash light to see through the hole, it was completely dry, now can i use tap water, or ONLY distilled water, the type of agm battery i have is xs power 4800
I did this on a CLARIOS MOTORCRAFT H6 battery. Voltage and CCA came up. Waiting to see if battery health will recover as well so it's on a pulse charger right now. Cells were all low sort of dried. 😢
Dionich, one tip, look at the hobby chargers, once you learn them, you will skyrock in terms of battery knowledge because they can charge several type of batteries, in different voltages and currents, meaning you can throw away all chargers you have. I have the skyrc t200 model which is awesome, its old, if you think of buying one look at the new models and buy a dual or even quad port so you can charge several batteries at once.
5 years of using agm..... went to the service opened and filled with water. he cautioned me that because battery was opened the vacuum is lost so the capqcity will be questionable but adding water prolongs the battery life. didnt need any regeneration since he poited out that my mppt solar system is perfect for the agm charging. no higher voltage involved and i did loose some 10% capacity which is now at 2/3rds. not bad for 5 years of torture. hope this info helps somebody.
Did you need to discharge the battery at all when you opened up and filled with water. Or just opened/ filled with water/ closed and reused or charged up?
@@kylerprophet2058 nothing. he opened it up and topped up the water to specs and recommended me to charge up to full. did that and et voila. nothing special about it.
@@rubendamian8636 look im no expert im jist telling what he told me. but i tend to agree with him. even agm has exhaust valve in case it needs to vent out pressure so logicaly it needs vacuum otherwise it would leak and would not be sealed. but thats just my thinking of it. i know my battery is still good. i know he gave me the look as to why even open the agm. well after looking at some yt videos i decided im goingvthru with it. btw restoring battery from dead.... its BS to me. yt is full of BS videos last few years.
The high temperature extremes under the hood of a car especially in hot climates will dry out the battery. It even causes the chemical makeup to degrade faster, but rehydration will most certainly give more life as long as it hasnt dried out too much
Hey man thanks for the video. I need to replace my original 15 year old BMW AGM battery is at 12.33v right now, Never had an issue except I had some some rough starts lately and the radio stays on only for a minute then it turns off with the low battery symbol on the dash. Since new BMW battery is out of my price point, in your opinion, should I try this process or buy new budget replacement battery around 200$ How long do would you say the original recovered battery would last?
Hey, mate. 15y thats a lot. I would say better buy a new one, Varta, Exide or some other good brands. Your battery internals are probably already tired.
Unfortunately every one of the batteries that we have in garage (Agm and flooded) are completely sealed. I went shopping for one and found that they don´t make them with filling caps anymore. I´ve checked Varta, Banner, Exide, Bosch...none of them had the plugs even under the sticker it was only plastic. :(
I've seen a vid - the guy was cutting the sealed plastic cover and underneath were the plugs. th-cam.com/video/lhM09OTRZJ8/w-d-xo.htmlsi=ugJnAEspBWL-Fcdk
Oh wow, cool, thanks!@@dionich I have Exide EK950 AGM 95Ah and Varta Silver dynamic 105Ah...I´ll try to open them to see if I can add electrolyte and run a few de-sulfating cycles on them. I may have found out why the Exide AGM died...my car (Old POS Bmw E60 with the stupid IBS cable on the battery) is over-charging with 14.8-15.2 Volts. I´ve heard from another channel that this will boil the electrolyte and it will evaporate. Guy in the video had the exact same Exide battery and said it is 2 Kilograms lighter because of that...incredible. :D
well my agm battery (exide) stopped to hold charge, charged to 100 after first crank it lost about 45%, thanks for video will test this method out, only need recon enabled charger..
I've added about 50ml to each cell, but the top of the "plates" are still dry. I realize it's different with an AGM and they should not be fully flooded. I don't have a "as new" weight, so I'm wondering if I've added enough. I do note that the battery gets pretty warm when charging.
@@bradanesi3998 I also recommend charging if possible before topping the electrolyte off with distilled water. then let them sit for 24 hours before checking and adding water. This is because water should only be added enough to where the mats look wet while the battery is fully charged. Otherwise just be sure you don't overdo it and only add a small amount at a time. wait a while in between. The mats should look "moistened" not soaking with puddles everywhere.
Greetings brother, having trouble with a Bosch S5 017 12V 100Ah Battery. It was drained since some time, just removed it from my Car, put it on my Stanley Automatic Battery Charger which has a Recondition Function, however it did not detect (usually evident when i connect the 2nd black clip to negative a beep is heard). When i try to click on the Voltage Function or the Charge Function or even the Recondition Function, there is nothing. Any suggestions?
If your battery is too low, a smart charger will not recognize it as a battery and will not start the charging process. You need to connect a second 12 volt battery in parallel with the battery you are trying to charge so the charger will "recognize" it. After a period of time, once the voltage in the low battery starts to rise, you will be able to disconnect the second battery and the charging will continue on its own...
Connect 2nd good battery to the dead one and put charger on. Charger will register the voltage of good battery and will start charging. After some time you can disconnect the good battery.
For normal flooded lead acid, its normal to add water, but AGM many manufacturers say with CAPS LOCK never add water... Would be nice to have follow up@@dionich
Dionich's, I was impressed by seing the labels in the battery in portuguese, are you Brazilian? Moura(the brand of this battery) is very popular in Brazil. Excelent video/content. Subscribed
Never fill a battery then charge it because it doesn’t give it an accurate reading and will cause boil over and corrosion. Do a full charge and then fill it that’s how you keep batteries lasting. I have a battery from 09 barely hanging on but still kicking well past mfg dates
Good video. I don't have a AGM battery in my 2001 BMW 530i, and I use a Pulse Tech PowerPulse passive battery desulfator for the past three years, Pulse Tech claims their patented frequency they use will extend the battery life up to three times.
Really not worth the time and effort. Just buy another one with 4-5 years of free replacement warranty. Not that battery was bad in this case or anything. Super low resistance and high amps. Must be a truck battery or something because my mazda starts with 350amp shitty old battery lol.

Thanks. Battery sticker says same 950 point both for CCA and EN. Will try both modes next year.
@@dionich Oh yeah! Bit odd. Might mean it's over specced for a 950 CCA so it can pass 950 EU. I've not heard of "GS" I assume that German.

Distilled. Not all batteries could be revived though. Batteries could have internal damage or lack of proper acid level.
@@dionich ok, i see what u mean, ima just try it out in the morning and see whats going to happen

There's nothing to lose if you're going to discard the battery anyway.

Not true. If it’s dead with high resistance you could do it in a calibrated manner. Not flood it. Usually just 10-50ml depending on the capacity.
