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.

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 8 месяцев назад

Hey. Sorry, cannot help you out here.

@cutedrdave 8 месяцев назад

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 7 месяцев назад

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.

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 7 месяцев назад

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

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 6 месяцев назад

I've seen a vid - the guy was cutting the sealed plastic cover and underneath were the plugs. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lhM09OTRZJ8.htmlsi=ugJnAEspBWL-Fcdk

@vitek310 6 месяцев назад

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 6 месяцев назад

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

@bradanesi3998 29 дней назад

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 29 дней назад

@@bradanesi3998 Mats should look wet. Add more water

@bradanesi3998 27 дней назад

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

@realflow100 26 дней назад

@@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.

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

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

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.
