How to use
Connect the charger to the battery following the polarity markings: positive clamp to the battery’s positive terminal and negative clamp to the negative terminal or a recommended chassis ground point. Ensure the charger is switched off or disconnected from mains before making the connections. After connecting, plug the charger into the mains supply and select the appropriate charging mode if applicable. Monitor the charging process until the battery reaches the recommended charge level, then disconnect mains power, remove the clamps starting with the negative connection, and store the charger in a dry place.
Usage recommendations
Use the charger only with 12V lead-acid batteries and follow safety instructions regarding ventilation, avoiding sparks and observing correct polarity. For long-term battery maintenance, apply periodic maintenance charging rather than leaving the charger continuously connected unless the charger explicitly supports float mode. Inspect battery condition before charging; do not charge visibly damaged or leaking batteries and follow local regulations for battery disposal and recycling.
