Equalize Charging
Many lead acid battery manufacturers recommend periodic equalize charging to counter
cell charge imbalance and capacity robbing sulphation. Equalizing helps to improve
battery performance and lifespan by encouraging more of the battery material to become
active.
Battery equalization is a controlled overcharging method that reduces sulphation and
mixes up stratified electrolyte and reactivates unused areas of the plate material.
Periodic equalizing can help to regularly restore flooded lead acid batteries to a healthy
state of charge.
Consult the battery manufacturer's recommendation for equalize charging settings.
Sealed lead acid, gel, AGM, and lithium ion batteries should not be equalized unless
recommended by the battery manufacturer. Consult the battery manufacturer for optimal
charging procedures when using sealed batteries.
When Equalize mode is enabled, the battery is charged from bulk to absorption, and
then to the equalize phase. The Conext XW Pro will transition from the absorption phase
to equalize if:
n The DC charge current is below 2% of the configured battery capacity (forexample,
8.8 A for 440 Ah).
n The absorption time is exceeded (for example, 180 minutes).
After absorption, the maximum charge DC current is set to 10% of battery capacity (for
example, 44 A for 440 Ah). This constant current charge will continue until the voltage
has increased to the equalize voltage at which point the battery will be regulated at the
temperature compensated equalize voltage.
If the battery capacity is set to zero, the equalize charge current is fixed at maximum 44
A (Ah=0 effectively disables the exit current criteria for the absorption charge stage,
making the absorption stage defined by time only).
Equalization duration is fixed at one hour.
