For Lithium (and also NiCd, NiMH) CAPACITY is given in mAh
(at BATTERY SETUP screen)
. Selection is in
increments of 100mAh. If your battery does not fall on an exact division of 100 - for example battery is rated
670mAh - you should choose the next closest setting. In our example, 700mAh would be appropriate. CURRENT
is set in Ampere
(at CHARGE MODE screen)
, so divide mAh by 1000 to get Amperage. For 700mAh, current is 0.7A
for 1C, up to 1.4A for 2C max. For 1800mAh, 1.8A~3.6A and so on….
Lead Acid Batteries: Set Voltage of the battery, Amp Hour (Ah) rating of the battery at BATTERY SETUP screen,
and Charge Current at CHARGE MODE screen. Consult the battery manufacturer’s documentation to determine all
of these settings.
Number of Cells in Lead Acid Battery
Pb
1 cell
2.0V
2 cells
4.0V
3 cells
6.0V
4 cells
8.0V
5 cells
10.0V
6 cells
12.0V
For NiCd and NiMH: Set Voltage of the battery, Number of Cells (C), and Capacity in mAh at BATTERY SETUP
screen, and Charge Current at CHARGE MODE screen.
If you only know the nominal rated voltage of the pack, but not the number of cells, divide voltage by 1.2 to get
cell count: Example: 9.6V / 1.2 = 8 , so there are 8 cells in the pack.
At the NiCd/NiMH CHARGE MODE screen, there is a setting for
\
: Delta V (sensitivity to voltage change for
charge termination). If you have no good reason to change the defaults, don’t touch this. By default, NiCd is
8mV/C and NiMH is 4mV/C, in case you change it by mistake…
Note again that in AUTO modes for NiCd (A1)and NiMH (A2), you do not need to set anything. Just connect the
battery after choosing the correct Auto Mode, and press ENTER to start charging.
Other Screens and Settings
DISCHARGE MODE:
D : Discharge rate in ampere (A), 0.1A increments
xV/CELL : “x” is the stop discharge voltage cutoff per cell
Note: Typically xV/CELL would be 0.9V for NiCd/NiMH, 3.0V for Lithium. However, except for testing the condition of a lithium
pack, discharge or cycling of Lithium batteries has no advantage and is best avoided.
CYCLE MODE:
DCH/CHG : Choose to Discharge first, then Charge OR
CHG/DCH : Choose to Charge first, then Discharge
TIME : Number of cycles to perform ( 1 = one cycle, 2 = two cycles…)
USER CONDITION SETUP:
The four starred *settings below are global and affect all memory positions. Push ENTER when at the USER
CONDITION SETUP screen to access these four sub menus, then UP/DOWN to make changes (if desired), then
ENTER again to move to the next screen (SETUP button is not used at all).
*TEMPERATURE: When the optional temperature probe (HP-EOS1210I-SEN) is attached to battery and charger,
the temperature in degrees Celsius at which charging will terminate. Use UP/DOWN buttons to choose an
appropriate temperature in a range from 10 to 55 degrees. Press ENTER to continue.
*TRICKLE CHARGE CURRENT: (does not apply to Lithium batteries)
Trickle charge is a low-current maintenance charge that continues after the normal high-rate charge cycle is
finished.
AUTO : Determined by charger algorithm (best in most cases)
0mA : OFF - No trickle charge
100mA~500mA trickle charge current, in 100mA increments.
*DELAY BETWEEN CHARGE/DISCHARGE:
Applies only when CYCLE MODE is in use, from 1 to 30 minutes in one-minute increments.
*SOUND VOLUME: OFF, or one of five choices for tone. Press UP/DOWN to hear each tone type. ENTER to
choose and exit. (note: it says “volume”, but it is really tone type…)
Once you are satisfied that all the settings in the current memory position are correct for your battery,
you are ready to charge, discharge, or cycle your pack!
Note: When an LBA10 or compatible balancer is not
connected to the 1210i via DataPort, the initial screen after charge is started will recommend use of the LBA, for best safety.
