Setup About Charging Batteries Batteries draw as much power as they need from charger. The charger does not force current into battery. When a battery is close to being 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 high end. As the battery charges, the reading will move down toward the low end, resting on zero, when battery is fully charged. See Figure 1 below.
Output Selector Controls Timer: The Timer prevents overcharging while allowing a battery the needed time to obtain a satisfactory charge. To set the Timer, you must know the size of battery in ampere hours or reserve capacity in minutes, and the state of charge. Often the state of charge is not known, which is why the Timer is limited to 3 hours. With the aid of a battery load tester (not included) the state of charge can be obtained in a few seconds.
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.
