I have recently seen a year old video about an electronic desulfator that fixed certain types of old battery issues.
Do you have any knowledge about the topic that could potentially restore old batters to working condition?

Sulfation is more of a problem for deep cycle batteries.
Your car battery has one job that it's designed for. Start the car and that's it. Then it is quickly recharged soon after.
It should never spend much much time below 90% charge.
Modern cars have computer controlled charging that monitors batteries pretty closely. You don't need any gizmos for your battery if you don't abuse it.
I’ve tried slow trickle chargers to try and desulfate a battery. With marginal results. TBH, IMHO, it’s not worth the effort, unless maybe you are running a business or fleet.
It’s more cost and time effective to buy a new battery.
To desulfate a battery, you have to take the battery out, lug it into the garage or the house, plug it in, wait forever, and then lug it back out into the car and install it. And then do it all over again.
Might as well install a new battery with all that lugging and time waiting.
Unless you have time on your hands. That’s the only reason I tried it, because during the pandemic, I was stuck at home with nothing to do. So I tried it. With so so results.
