If you are talking about recovering lead-acid batteries, then after cleaning the plates, the first liquid to be added is usually a standard electrolyte solution (diluted sulfuric acid in the correct ratio)—regardless of whether it comes from Paraguay or any other country. The important thing is the correct type, proper concentration, and technical standards, not the geographical origin.

Hello from Langley B.C. Canada. I am in the process of restoring an old battery, a load tester is what you need to see if the battery holds a charge after restoring and charging. ✌

Red is positive,black is negative

Did u notice he put the cables wrong lol 😂

Desde piedecuesta Santander en colombia, mil gracias

what's are the things did you put inside the battery

From cameroon

Thank you so much

I am from bangladesh, I want to know how long will this sustain after your repair? 3 months? 6 months, more or less? I have a 200 amp Ips battery, I want to apply your technique if this realy work, pls confirm me the duration.

Your new battery will last ,just wrapped all side with insulator or silicone rubber matting, to minimize heat and after warranty, check water level ,add distilled water, keep 12.8v resting ,and alternator 13.7-14.5v charging volts

degerli  bilgileriniz için   çok teşekkürler Türkiye    İstanbul

Watching from India, good information

Wonder if the charge still worked after putting a load on it.

Hola desde cuba saludos grasias x la enseñansa

Bologna!  You might get the voltage up but it will not have the current to start a toy car.

Merci le service que vous aviez rendu

CLICKBAIT    this only works in certain situations

I like the contents of the video and the steps taken, but showing only 12.46 volts at the end of the video does not mean that the battery has the capacity to carry the heavy load demanded by the starter motor, it would have been great if you  tested it with a proper battery tester at the end and showed the results with a draw down load test with a proper battery tester  but hey thanks for the effort thanks for the video. also if the battery hasn't got the capacity to start a car you may still be able to use it on your lawn mower
