result in a weak cell which in turn can reduce the overall capacity of the battery. To improve the life
and performance of the flooded battery, Apollo Maxx provides a manual equalization program that
can be used. If it is recommended by the battery manufacturer, you can initiate the desulfuration
program manually. Once you trigger on the equalization program, the Apollo Maxx will perform
equalization charging.
After 30 minutes, it will quit EQ and enter into float charging.
Check the electrolyte level and refill the battery with the distilled water if necessary.
If you want to come to normal charging, you need to stop equalization charging and switch off
the unit.
Switch on the unit again, then you will have your equipment back to normal charging.
During equalization, the battery generates potentially flammable gases. Follow all
the battery safety precautions listed in this guide. Ventilate the area around the
battery thoroughly and ensure that there are no sources of flame or sparks in the
vicinity.
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.
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 may damage your batteries if it is not performed properly. Always check battery
fluid before and after equalization. Fill the batteries only with the distilled water.
Always check the equalization switch is set back to OFF after each time’s equalization.
Follow the battery manufactures’ recommendations on equalization vary. Always follow the
battery manufacturer’s instructions to properly equalize the batteries. According to the 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:as a kind of protection, equalization charging can be performed if and only if you
set the battery to be a traction, Flooded /OPzV batteries. If you choose the AGM, GEL or
Lead-Carbon, EQ charging can’t be performed.
