flooded batteries every 1 to 3 months or every 5 to
10 deep discharges. Some batteries, such as the L-16
group, will need more frequent equalizations.
The difference between the highest cell and
lowest cell in a battery can also indicate the need for
an equalization. Either the specific gravity or the cell
voltage can be measured. The battery manufacturer
can recommend the specific gravity or voltage values
for your particular battery.
Preparation for Equalization
First, confirm that all of the system loads are rated for
the equalization voltage.
Consider that at 0°C (32°F) the Equalization
voltage will reach 16.75 Volts for L-16 batteries with a
temperature sensor installed.
Disconnect any loads at risk of damage due to the
high input voltage.
If Hydrocaps are used, be sure to remove them before
starting an equalization. Replace the Hydrocaps with
standard battery cell caps. The Hydrocaps can get
very hot during an equalization. After the equalization
is finished, add distilled water to each cell to replace
gasing losses. Check that the battery plates are cov-
ered.
Equalize a Sealed Battery?
The Battery Charging Settings table (see table 4-1 in
this section) shows two sealed battery settings with an
Equalization cycles. These are minimal “boost” cycles
to level individual cells. This is not an equalization,
and will not vent gas from sealed batteries that require
up to 14.4V charging (12V battery). Many VRLA bat-
teries, including AGM and gel, have charging require-
ments up to 14.4V (12V battery). Depending on the
battery manufacturer’s recommendation, the “boost”
cycle for sealed cells can be disabled by setting the
equalize setting switch to manual, if required.
Battery Charge Settings
The ProStar provides seven (7) standard battery
charging settings that are selected with the settings
switches (see Table 4.1 above). These standard charg-
ing settings are suitable for lead-acid batteries ranging
from sealed (gel, AGM, maintenance-free) to Flooded
and L-16 cells. In addition, an eighth charging set-
ting provides for custom set-points using MSView
TM
PC software. Table 4-1 below summarizes the major
parameters of the standard charging settings. The
shared settings in Table 4-2 are common to all battery
types.
NOTE: These settings are general guidelines for
use at the operator’s discretion. Consult the battery
manufacturer for optimal battery charge settings.
