NOTE
: The battery voltage can increase above the float voltage
when using an external charging device such as PV arrays, wind
turbines, and micro-hydro generators. Be sure to include
appropriate charge management equipment with all external DC
sources.
Equalize Charging
Many battery manufacturers recommend periodic equalize
charging to counter cell charge imbalance and capacity-robbing
electrolyte stratification. 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
mixes up stratified electrolyte and reactivates unused areas of the
plate material. Periodic equalizing can help to regularly restore
batteries to a full and healthy state of charge.
Consult the battery manufacturer's recommendation for equalize
charging settings. Sealed batteries should
never
be equalized.
Consult the battery manufacturer for optimal charging procedures
when using Lithium and Sealed batteries.
When Equalization is enabled, the battery is charged from bulk to
absorption, and then to the equalize phase. The Freedom XC will
transition from the absorption phase to equalize at an equalize
current set to 10 A.
After absorption, this constant current charge will continue until
the voltage has increased to 16 V
Z
.
Equalization duration is fixed at 1 h.
