Setup About Charging Batteries Batteries draw as much power as they need from the charger. The charger does not force current into the battery. When a battery is close to dead or very low charged, it will want to draw more current. When a dead or low battery is charged, the charger’s ammeter will register at the high end. As the battery charges, the reading will move down toward the low end, resting on zero, when the battery is fully charged. See FIGURE 1 below.
2. If necessary, add distilled water to the battery cells before charging. Read and follow the battery manufacturer’s instruction manual. Never add water to a battery while attached to a charger, or in close proximity to the charger. Do not overfill. 3. Clean battery terminals. 4. Check the battery manufacturer’s instructions on whether or not to have the cell caps on when charging. If not stated, leave the cell caps on. CHARGING BATTERIES Caution: Do not overcharge maintenance-free batteries. 1.
