Charger
Charging will begin. The START/STOP LED will light steadily. The ES3 will now enter the Auto Cell Sizing Test Charge
indicated by the displayed text message on the LCD and the ‘bouncing ball’ on the bar graph. After two minutes in the test
phase, the charger will shut off and enter the Auto Cell Selection phase. The display will show the count down from two
minutes. The ES3 will then choose the appropriate battery cell size based on the voltage response of the battery.

The charge cycle starts and will reach steady state start current within a few seconds. The LED bar graph will indicate the
percent charged status of the battery and the display will rotate through the following charge parameters.
Charger Current (Charger output current)
46.3
Amp Hours Returned (Amp-Hours returned to Battery)
268
Charge Time (Total Charge Time)
3:12
Battery Volts/Cell (Individual Cell Voltage)
2.56
These values are displayed in rotation for about 3 seconds each. The display settings can be changed so that one or all
the above parameters will be displayed. The default setting is for all parameters to be displayed.
CAUTION: To prevent arcing and burning at the connector and possible battery explosion, press the
START/STOP pushbutton first to stop the charge cycle before removing a battery that is currently on charge.
4. When the battery reaches Gassing Voltage, the yellow 80% LED will light and the charge current will begin to taper.
The charge cycle enters constant voltage or E mode.
5. After the current tapers to the finish-rate current, charging will continue until the battery voltage flattens or the time in
taper equals 5 hours. If no Equalize charge is to be applied to the battery, the charger will stop and the display
will show Cool Down. Cool Down is an idle time period that allows the battery to cool off before use. After a 1
hour Cool Down period (default), the display will show “Done”.
6.
NOTE: If the battery is to receive an Auto Equalize charge, the charge cycle continues for 3 more hours at finish-rate
current and then stops, displaying Cool Down.
7. When the battery is fully charged the green Charge Complete LED will light, the START/STOP LED will extinguish
and the charger will shut off. At this time the battery is at full capacity and ready for use.
If Cool Down is not selected, the display will read “Done” when the charge is complete.
