Charge time during this step varies between 10 and 120 minutes,
influenced by initial battery State Of Charge and health as measured in
STEP 3, and current draw by connected circuitry.
For safety reasons there is an overall charge time limit of 72 hours
for STEP 4, 5 and 6.
Delivery of current to the battery is interrupted for 30 minutes**
to allow the program to determine the battery's ability to retain
charge.

estimated state of charge percentage (SOC%).

For 24V batteries: 27.2V nominal at 20°C (68°F). The float voltage is

inversely regulated according to ambient temperature; i.e., voltage is
increased at lower temperature, decreased at higher temperature.
Adjustment: -0.004V / cell / °C above or below 20°C (68°F).
Continuous float maintenance charge will be applied to the battery if
the charger sensed that connected circuitry has a current draw
exceeding 200mA, otherwise the charger proceeds with the standard
maintenance mode. Standard maintenance mode consists of 30
minute float charge periods followed by and alternating with 30 minute
'rest' periods, during which there is no charge delivered. This "50%
duty cycle" prevents loss of electrolyte in sealed batteries and
minimizes gradual loss of water from the electrolyte in batteries with
filler caps, and thereby contributes significantly to optimizing the
service life of irregularly or seasonally used batteries.
During "float charge" a continuous LOW CURRENT PULSE IS DELIVERED
TO PREVENT SULFATION, further extending battery power and life.
