Performing An Equalization
Turn off or disconnect all DC 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 without a remote display:
1. Check the battery electrolyte level. If necessary, refill with distilled water only.
All the cells should have similar electrolyte levels. If the levels are widely
different, it will influence the relative concentration of acid, thereby affecting
the specific gravity measurements.
2. Verify that all banks are in either float or rest mode.
3. Press the equalize push button beside the DIP switches once to equalize bank 1,
twice within three seconds to equalize bank 2 and three times within three
seconds to equalize bank 3.
4. Monitor the specific gravity of each cell of the battery during equalization with
a battery hydrometer.
The equalize cycle will terminate in one hour.
Check the specific gravity of each cell and repeat the equalization cycle until
they all meet the battery manufacturer's specifications for specific gravity or
until the specific gravity stabilizes relative to each other for an hour.
5. The charger automatically exits equalization to float mode or rest mode after 1
hour. To manually exit equalization mode early, press the equalize push button
once.
6. When equalization has finished, check the battery electrolyte level. If
necessary, refill with distilled water only.
