Safety Timer Calculation

Lithium (Lilo/LiPo/LiFe) Program

When charging NiCd or NiMH batteries, divide the capacity by current, then divide the result by 11.9. Use this
as the number of minutes for the safety timer setting. If the charger stops at this time threshold about 140% of
the capacity will have been fed in to 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=1100)/11.9=92 minutes

1000mAh

1.2A

(1000/1.2=833)/11.9=70 minutes

This program is only suitable for charging/discharging lithium-polymer batteries with a nominal
voltage of 3.3/3.6/3.7V/cell. Different batteries have different charge techniques. There are two
methods of charging, constant voltage and constant current. The charge current varies according
to battery capacity and specification. The final voltage is very important; it should precisely match
the voltage of the battery: LiPo is 4.2V, Lilo is 4.1V, and LiFe is 3.6V. The current and voltage of the
battery should be correctly set.

When you want to change the values of parameters, press the ‘START/ENTER’ key to make it blink
and then use the ‘+’ or ‘-’ keys to change the value. Then press the ‘START/ENTER’ key again to
store the value.
