Battery Preparation
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.

Charging Tips
Read the entire manual before using the Battery Manager. The
tips below serve only as a guide for specific situations.
Reviving a Battery: To charge your battery enough to start your
vehicle, it is not necessary to wait for the entire charging process to
be completed. When the battery status displays 3 yellow LEDs, the
battery is usually charged enough for the vehicle to start normally.
Completing an Interrupted Charge: If the charging process has
been interrupted and restarted after the Battery Manager displays
a battery status of 4 yellow LEDs, the Battery Manager may enter
Maintain Mode. However, if the original charge was started using
the 6A rate, the charge can often be completed using the 2A rate.
