While preparing to charge a battery, read and follow these
guidelines:
1. Ensure you’re working with a 12- or 6-volt lead-acid battery.
To determine the voltage of the battery, refer to the vehicle
owner’s manual or the battery markings. Set the Battery
Manager to the 6V or 12V mode accordingly.
2. Clean the battery terminals. Be careful to keep corrosion from
getting in or around your eyes.
3. Wear safety glasses. (See “Personal Safety Precautions” section
this manual.)
4. Read all of the battery manufacturer’s specific precautions, for
example, removing or not removing vent caps while charging
and recommended rates of charge.
5. To add water to batteries with removable vent caps, carefully
pour distilled water into each cell until battery acid reaches
the level recommended by the manufacturer. This helps purge
excessive gases from the cells. Do not overfill. If the battery is
sealed, with non-removable vent caps, no action is necessary.
