Procedure to Equalize Flooded Battery:
DANGER
: Explosion Hazard. The battery generates explosive gases during equalization.
Follow all the battery safety precautions listed in the manual.
CAUTION
: Risk of Battery and Equipment damage. Only the Flooded lead-acid can be
equalized. Consult your battery manufacturer or read the battery manual when you try to
equalize your batteries. Disconnect any DC load connected to the battery, as during
equalize mode, the charger will produce 16V to the batteries. You must monitor the battery
specific gravity throughout the equalization process to determine the end of the equalizing
cycle.
Charge batteries in one full cycle before you start equalized the batteries. Check the battery
electrolyte level. If necessary, refill with distilled water only. All cells should have similar
electrolyte levels. If distilled water is added, batteries must undergo a complete charge cycle.
The charger cannot determine when to terminate the equalization of the battery. A one hour
time-out is set and this is used as a safety feature to require the user to continually re-activate it
as necessary after checking batteries manually.
During equalization mode the other two banks are disabled.
Use the following procedure to setup the charger for battery equalization.
