Once the Delta Peak threshold is set manually, the charger will use
this setting, even if it is not an appropriate setting for the battery.
Please follow the included recommendation on peak threshold
settings. Damage to the battery can occur if you are not careful.
8. The 977 also has the ability to perform a “capacity” charge. By
pressing the “Display Select” button again, you will see mAh
displayed with two bars. At this point you can enter the capacity to
which you wish the 977 to charge by pr or -. Once you press
+ or -, the unit will take the value as capacity limit. The 977 will not
charge above this capacity. However, if a peak is detected (based on
the peak threshold selected) before this capacity is reached, the 977
will terminate the fast charge cycle. After the charge/discharge cycle is
started, this display will show the amount of charge/discharge in mAh.
If you wish to perform a normal peak charge, entering the battery’s
capacity is not necessary. Only change if you wish to perform a
capacity charge.
9. The 977 has the ability to perform a “timed” charge. Pressing the
“Display Select” will bring you to the timer function (Min) with two bars.
Here, you can predetermine the length of the charge cycle in minutes.
As with the capacity charge, if a peak is detected before the selected
time, the 977 will terminate the fast charge cycle. After the charge/
discharge cycle is initiated, this display will show the elapsed time of
the cycle. Press the “Start” button at any time to begin charging/
discharging.
If you wish to perform a normal peak charge, entering the length of
charge time is not necessary. Only change if you wish to perform a
timed charge.
10. Once the charging starts, you cannot change settings. If you wish to do
so, please press the “Stop” button to stop the channel you are
currently operating.
11. During the charge cycle, the voltage, charge rate, power status*, peak
threshold setting, current amount of charge/discharge in Amp, and
charge time can be viewed by pressing the “Display Select” button.
* Power status is the amount of available power, out of 100, that the
selected channel is currently utilizing. If power status shows 100,
this is an indication that the displayed charge current is the
maximum current that the charger can provide for that particular
battery. This will happen when you charge 9 cells battery with 5Amp
setting. The real current will be far below 5Amp.
12. Charging/discharging can be stopped at any time during the cycle by
pressing the “Start/Stop” button.
13. When the fast charge/discharge cycle is complete, the unit will beep once
and the word “stop” will blink on the screen. At this time, you can scroll
through the displays to check the finishing values mentioned above such
