  If the 'Full/Float' light on your Schauer Battery Charger doesn't illuminate, it could be due to several reasons. The battery capacity might be too large for the charger, causing it to time out; in this case, verify that the charger specification matches the battery capacity. Alternatively, the battery might be defective and require replacement. Another possibility is that the battery is severely sulphated; try switching the charger off and on, then select a higher charge rate setting, ensuring it doesn't exceed your battery's maximum charge limit.

Why does my Schauer Battery Charger have no DC output?

  Nancy TaylorAug 22, 2025
  If your Schauer Battery Charger has no DC output, it may be due to a short circuit in the output. Inspect the DC connection between the charger and battery, making sure there are no short circuits. Another possible cause is reverse polarity connection to the battery. Ensure that the crocodile clips or ring terminals are connected with the correct polarity.
