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.
Equalization charging was effected after bulk and absorption, if the battery was flat,
it will take long time to do the EQ, therefore suggest start the equalization charging
when battery SoC is above 90%.
EQ charging should be done when grid is stable, if the grid is cut in the course of
equalization, the EQ will be failed, it will need to reset the EQ again.
Important tips on Battery Equalization
Frequency:
Maximum once a month, for heavily used battery, you may wish to equalize your
battery. For battery with light service only need to be equalized every 2-3 months.
Important:
Equalization can damage your batteries if it is not performed properly. Always check
battery fluid before and after equalization. Fill batteries only with distilled water.
Always check the equalization switch is set
back to OFF after each time’s equalization.
Battery manufactures’ recommendations on equalization vary. Always follow the
battery manufacturer’s instructions so batteries are properly equalized. As a guide, a
heavily used battery may require equalization once a month while a battery in light
duty service, only needs equalizing once every 2 to 4 months.
Battery type:
ONLY perform equalization to Flooded or OPZS batteries. Do not equalize Gel, AGM ,
Lithium-ion (LFP), Lead Carbon batteries.
