Equalizing Batteries
Equalization charging is the process of deliberately charging a battery or battery bank at a
high voltage for a set period of time. Equalize charging remixes the electrolyte, helps to
remove sulfate buildup on the battery plates, and balances the charge of individual cells.
Make sure to read all cautions and warnings regarding equalization charging batteries
before allowing an equalization charge to occur.
Note: In a system where more than one device is capable of equalizing batteries (such
as a system including multiple charge controllers and Conext XW+ or Conext XW Pro
Inverter/Charger), 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).
WARNING
HAZARD OF EXPLOSION
Equalization charging generates explosive gases which might escape from the battery.
Make sure adequate ventilation is provided. Never leave a battery unattended during
equalization. Follow the battery manufacturer's recommended actions for determining the
appropriate point at which to stop the equalization process, for example, by monitoring
electrolyte specific gravity.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
NOTICE
BATTERY DAMAGE
Never equalize a battery more than necessary. Equalization can damage your batteries if
performed too frequently or done improperly. Always check electrolyte level before and
after equalization. Fill with distilled water according to the battery manufacturer’s
recommendation.
The charge controller enables equalization only when the battery type is set to Flooded.
Equalize mode is disabled if you have selected GEL and AGM as the battery type. As a
general rule, do not equalize a battery unless there are provisions to add water to it and the
manufacturer recommends equalization.
Failure to follow these instructions can result in equipment damage.
