Equalize-Charging the Batteries
Many battery manufacturers recommend periodic equalize charging to level out the
voltage between individual cells, improving battery performance and lifespan.
Over time, the battery’s electrolyte can become stratified, causing inactive areas
in the plate material. If this condition is allowed to continue for extended periods,
the battery plates can sulfate and become unusable. Equalizing the batteries is a
controlled overcharging method that mixes up the electrolyte and reactivates the
unused areas of the plate material, restoring batteries to a full state of charge.
Consult the battery manufacturer’s recommendation for equalize voltage
settings. Equalization time is fixed at 60 minutes.
To start equalizing the batteries:
u On the device Setup menu, highlight Equalize and select Enabled.

NOTE: Only flooded or vented batteries should be equalize-charged.
Hydrogen and oxygen gases are produced when batteries are equalize-
charged. See warning below.
WARNING
EXPLOSION HAZARD
Provide adequate ventilation and remove all sources of ignition to prevent
explosion.
Failure to follow these instructions can result in death or serious injury.
IMPORTANT: In a system where more than one device is capable of equalizing
batteries (such as a system including Solar Charge Controllers), there is no
system-wide equalization command for all devices. To equalize with multiple
devices, each would have to be enabled individually. Alternatively, equalization
can be performed using only one device. During the equalization process, one
device applies the equalization charge while the other devices continue to
operate in synchronized charge mode, typically in float (three-stage charging) or
no-float (two-stage charging).
