How to use

Connect the charger to the battery following the polarity markings: positive clamp to battery positive and negative clamp to battery negative or appropriate grounding point. Ensure the charger is powered from a suitable AC supply and select settings if the unit includes a battery type selector; otherwise the charger will apply its built‑in profile for the detected battery chemistry. Monitor the charging process and allow the charger to complete its cycle or switch to maintenance/float mode according to the charger indications. After charging, disconnect AC power first and then remove the clamps, starting with the negative terminal to reduce risk of sparks.

Usage recommendations

Use the QOLTEC Monolith 10A 12V charger in a dry, well‑ventilated area and avoid exposure to rain or direct moisture. Verify battery condition before charging; do not attempt to charge visibly damaged or leaking batteries. For best battery life, follow manufacturer guidelines for charge acceptance and avoid prolonged storage at low state‑of‑charge. When charging different battery chemistries, confirm the charger’s selected profile matches the battery type.
