4.4.2 Typical Equalizations
The automatic equalizations will occur at the selected charging program from Dip Switch
4~6. When an equalization begins (auto or manual), the battery charging voltage increases
up to the equalization voltage (Veq). The battery will remain at Veq for the time specified
in the selected charging program.
The equalization process will continue until the voltage has been held above the bulk setting
for a cumulate period of two hours. A second manual equalization cycle can be started with
the pushbutton if needed.
If the equalization cannot be completed in one day, it will continue the next day or days
until finished. After an equalization is completed, charging will return to PWM absorption.
4.4.3 When to Equalize
The ideal frequency of equalizations depends on the battery type (leadcalcium,
lead-antimony, etc.), the depth of discharging, battery age, temperature, and other factors.
One very broad guide is to equalize 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.
4.5 Float
When a battery becomes fully charged, dropping down to the float stage will provide a very
low rate of maintenance charging while reducing the heating and gassing of a fully charged
battery. When the battery is fully recharged, there can be no more chemical reactions and all
the charging current is turned into heat and gassing.
The purpose of float is to protect the battery from long-term overcharge. From the PWM
absorption stage, charging is dropped to the float voltage. This is typically 13.4V.
