Turn the ignition and all electrical consumers and remove ignition key. Remove the negative terminal of a battery Wait at least 2 hours. At this time, the battery can not be charged and discharged. Measure the open circuit voltage of the battery using a hand multimeter VAG 1526 B.
If the results of measurements performed open-circuit voltage battery charge, follow the steps below. Wait at least 2 hours. At this time, the battery can not be charged and discharged. Measure the open circuit voltage of the battery using a hand multimeter VAG 1526 B. If the open circuit voltage of the battery after the charge is less than 12.5 V, replace the battery.
