Video and sound quality at the highest standards! Great video:)

[@dionich]

Great to hear! Looks like the new headphones and the sound filtering compressors helped.

[@hapskie]

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.

outstanding video! THANKS

[@surge_vasquez]

Very informative. Thank you for the great video and info.

Excellent video thanks for sharing

Well done on the video!

Awesome 👏

Great video!

[@4Rracing]

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.

[@fenikx007]

Thx mate i did exactly what you do , and my Agm Back to life from 5,6V back to life

[@randygreen6652]

Your english is insanely good. Evenly* instead of eventually. Not sure why i felt the need. Im sure you know this.

[@dionich]

Good to hear that from a person whos English is probably a mother tongue! Evenly, indeed :)

[@Ratalala]

try VRLA, they create water for them selfs :)

[@user-mq3yy6vb9g]

ممتاز جدا

[@pand2aren]

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..

[@tyreetw]

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

[@dionich]

Distilled. Not all batteries could be revived though. Batteries could have internal damage or lack of proper acid level.

[@tyreetw]

@@dionich ok, i see what u mean, ima just try it out in the morning and see whats going to happen

[@MocroPlay]

@@tyreetw​​⁠, did you already have any succes in trying to revive your battery?

[@tyreetw]

@@MocroPlay just one battery, the other 2 are done

[@alessandrosiqueira9960]

Conseguiu recuperar a bateria amigo? Teve sucesso?

[@dionich]

Hi. Already almost 5 months have past since this repair. So far so good.

[@adnanrana6379]

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?

[@dionich]

Hey. Sorry, cannot help you out here.

[@cutedrdave]

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...

[@raymondb325]

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.

[@rm6857]

Any update about battery performance? I am very very interested.

[@dionich]

Job done in July. Still no problems and no fault codes

[@rm6857]

looks promising, any new internal resistance or SOH test have you done?@@dionich

[@dionich]

@@rm6857 Nope. Will check next summer. Will revert later on.

[@josemedeiros007]

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.

[@bradanesi3998]

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.

[@dionich]

@@bradanesi3998 Mats should look wet. Add more water

[@bradanesi3998]

@@dionich Okay, will do. Thanks for the input.

[@realflow100]

​@@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.

[@vitek310]

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. :(

[@dionich]

I've seen a vid - the guy was cutting the sealed plastic cover and underneath were the plugs. kzbin.info/www/bejne/opmwYWyFibeNgJosi=ugJnAEspBWL-Fcdk

[@vitek310]

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

[@dionich]

@@vitek310 Be carefull with cutting not to make a hole to the main battery compartment :) good luck!

[@danute125]

Geras, kaip laiko? O aš tik pakeičiau į kita Agm baterija. 😀

[@dionich]

Dar tik 4 menesiai praejo.

[@narz5869]

Just info for maintenance all know about that😅

[@paveljelinek772]

Evenly.. spread the water evenly, not eventually

[@rm6857]

Adding water to agm?

[@dionich]

Yeah, distilled water.

[@rm6857]

Varta says never open it and never add water

[@dionich]

I'm not a specialist here. Just following agm restoration procedures found in internet. Will follow up with the results.

[@rm6857]

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

[@gonzalezgenzaloz5372]

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

[@serGiena]
