- Check the battery acid level using the color indicator. Two different displays are possible:







Risk of explosion on discharged battery with visual indicator.

If the visual indicator has no color or is light yellow, the battery may not be tested or charged. Jump starting must not be used! There is a risk of explosion during testing, charging or jump starting. The battery must be replaced.

If the battery must be replaced, follow the disposal regulations. Refer to=> [ Pollution risk. ] Lead-Acid Battery Warnings and Safety Precautions.
