And when in the storage process for a NiCd/NiMH battery, the first time you press the + button you
will see the elapsed time along with the average voltage of the battery that will be shown when the
discharge process has ended. Pressing the + button a second time will also show the internal
temperature of the charger and the peak voltage of the battery during the charge or at the beginning
of the discharge process.
Storage Completion
Storage will end automatically when the battery reaches the per cell voltage or capacity set by you.
When this occurs you will see the following screen:
From there you can press the ENTER button once to display the data from the storage process, as
well as use the +/
– buttons to scroll through other screens, and on most screens you can press the
ENTER button to exit the storage process completely.
SETTING DATA MODE
The Setting Data mode of the TP1430C allows you to set the various default data settings for a variety
of functions. You can reach the Setting Data mode from any of the Charge, Discharge, Cycle or
Storage Mode screens by pressing the MODE button once. From there you can use the +/
– buttons
to scroll through the available screens/menus accordingly.
It is also important to note that the
following data settings apply to all memory profiles: Power Distribution, Input Power LVC,
Input Current MAX and Temperature Unit. All other data settings apply to the memory profiles
individually.
Charge End Voltage
The ‘…..CHG End Voltage’ sets the end voltage per cell the charger will achieve before
completing/ending the charge process. This value can be set for all chemistry types; however, you
must have the chemistry you would like to set the value for selected in the Charge Mode in order for
that chemistry to show appropriately in the charge end voltage screen/menu.
It’s also important to
note that the charge end voltage value can be set PER MEMORY PROFILE
so you can fine-tune
the end voltage of the battery, just as you can the chemistry type, capacity, and charge current rate.
This is helpful because sometimes batteries of the same cell count and capacity, but different internal
resistance/performance levels, may charge to slightly different end voltages when using the same
charge end voltage value. In those cases it may be helpful to have the same chemistry type, cell
count, capacity, and charge current rate values but different charge end voltage values in two different
memory profiles. To adjust this value simply press the ENTER button once and the value will flash.
Then use the +/
– buttons to increase/decrease the value per your preference and/or the guidelines
listed below.
For LiPo batteries, and LiIon batteries with a nominal voltage of 3.7V per cell (and full charge
voltage of 4.2V per cell)
, you can set the charge end voltage up to 4.24V per cell. And although the
maximum recommended charge end voltage per cell is 4.235V, due to slight variations in the
components and calibration of each charger, resistance of charge leads and cells/batteries, ambient
conditions and more, it is possible that when the value is set to 4.24V it will not actually exceed
4.235V per cell when checked with a calibrated Digital Volt Meter (DVM). We first recommend
charging with the value set to 4.20V per cell then checking the actual voltage per cell with a calibrated
