Safe timer Calculation
When charging NiCd or NiMH batteries , divide the capacity by, the current,then divide the result by 11.9, set this
number of minutes as the value for the safety timer setting . If the charger stopped at this time limit, about 140% of
the capacity will have been fed into the battery.
For example:
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1000)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
Lithium (LiIo/LiPo/LiFe/LiHV) program
The program is only suitable for charging Lithium batteries with a nominal voltage of 3.3/ 3.6/3.7 / 3.85V/cell.
Different batteries have different charge techniques. There are two linked processes termed as constant voltage
and constant current.
The charge current varies according to battery capacity and specification.
The final voltage individual cell is very important.
It should precisely match the voltage of the battery type: LiPo is 4.2V, LiIo is 4.1V, LiFe is 3.6V, LiHV is 4.35V.
The charge current and total voltage of the battery should be correctly set.
The final voltage is not adjustable and is set at safe value already.
When you want to change the values of parameters, please press the button to make it flash and then use the
or button to change the value.
Then press the button again to store the value.
