Sulfation in Faily new batteries 8-(
My neighbor asked me to look at her ClubCar DS, which she had batteries put in a year ago. I just *know* she let this thing sit dead all winter, but I ageed to have look at it with my hydrometer.
Does anyone have a reccommendation as to the best way to break sulfation?

Re: Sulfation in Faily new batteries 8-(
There are two types of sulfation: reversible (or soft sulfation), and permanent (or hard sulfation). If a battery is serviced early, reversible sulfation can often be corrected by applying an overcharge to an already fully charged battery in the form of a regulated current of about 200mA. The battery terminal voltage is allowed to rise to between 2.50 and 2.66V/cell (15 and 16V on a 12V mono block) for about 24 hours. Increasing the battery temperature to 50–60°C (122–140°F) during the corrective service further helps in dissolving the crystals.
