How to use
Connect the charger to the battery following the manufacturer’s instructions: attach the clamps to the battery terminals (positive first), then plug the charger into a mains outlet.

Monitor the charger’s LED indicators to follow the charging progress and test results. After the charger indicates completion or maintenance mode, unplug from mains before disconnecting clamps (negative first) to ensure safe removal.
Usage recommendations
For best results, clean battery terminals before connecting and ensure good clamp contact. Use the integrated test function periodically to assess battery health, especially before long storage periods. Avoid charging frozen batteries; allow them to reach above-freezing temperature first. Store the charger in a dry place when not in use and follow vehicle manufacturer guidelines for battery maintenance.
