Equalizing Flooded Batteries
3–9
Important Turn off or disconnect all loads on the battery during equalization. The
voltage applied to the battery during equalization may be above the safe
levels for some loads. Be sure to check battery electrolyte before and after
equalization. Fill only with distilled water.
To equalize your batteries:
1. Using a toothpick or other small object with a fine point such as a
paper clip or pen-point, press the recessed Equalize button on the
control panel below the Charging and Ready indicator lights. Press
and hold for about 5 seconds until both the Charging and Ready
indicator lights illuminate. The charger is now in equalization mode.
2. Monitor the specific gravity of each cell of the battery during
equalization with a battery hydrometer.
Equalization is complete when the specific gravity of each cell of the
battery remains constant. Most lead-acid batteries have a specific
gravity of approximately 1.265 when fully charged.
3. To terminate the equalization charge when the battery reaches the
target specific gravity, momentarily press the equalization button. The
charger will go to float mode for three-stage charging or monitor
mode for two-step charging.
4. If the specific gravity is still rising when the charger automatically
exits equalization to float mode after 6 hours, you can initiate further
equalization by pressing the Equalize button for five seconds.
5. When equalization has finished, check the battery electrolyte level. If
necessary, refill with distilled water only.
