The typical purpose of this program is to determine the
residual capacity of a drive battery.
In this program the charger discharges the pack using the
set discharge current (0.1 ... 1.0 A, left of screen) until its
voltage falls to the set final discharge voltage (1.7 ... 12.0
V, right of screen). To obtain a realistic capacity reading,
i.e. one which actually reflects the battery’s condition, the
discharge current should be set
substantially below 1C (capacity of the battery =
2
Ah —>
C =
2
A), and the final discharge voltage should be set to
around 1.7 V per cell.
Please do not be surprised if the charger does not deliver the charge current you have selected.
The charge program constantly monitors the battery’s voltage, and limits the current in order to
prevent excessive gassing of the battery.
The ULTRA TRIO PLUS 14 now charges the battery using the maximum possible current until
its voltage rises to around 2.3 to 2.35 Volts per cell. The charger then switches to a lower
current to bring the battery gently up to full charge; this process reliably fills the battery „to the
brim“.
The unit cuts off the charge process automatically when the battery reaches a voltage of
around 2.45 to 2.5 Volts per cell.
The effect of the automatic charge current adjustment system is to complete a full charge safely
in much less than the usual 14 to 16 hours.
When the charge process is terminated, the charger
emits audible tones for a certain period. At the same time
the screen also displays the message „END“.
