How long does it take for a battery to be fully desulfated?
For a regularly used car you can have your car battery fully desulfated within a 2 week period. When used together with a battery charger, it can take 1 to 2 days. Do note that the duration of desulfation varies due to the age and degree that a battery is sulfated. I recommend you to purchase our Digital Battery Analyzer, so that you are able to objectively gauge the status of your batteries before moving on to a new set for desulfation.
