As there is no manual in French and the English manual is not Locace the discharge system, I tell you the steps to follow:
1- inserting the batteries into the charger, charging begins
2- once over load, 3 beeps (very unpleasant) sound. END of the load
If desired (not required), you can perform a discharge cycle. This happens as follows:
3- You hold on the close button of the LCD. The CAP indication appears (for capacity)
4 The charger will charge your batteries Max then 3 beeps
5- discharge begins until it reaches the discharge voltage.
6- 3 Beeps again, and charging resumes
7- In the end load, you have in the actual load of your batteries display
At any moment, you press once on the button near the LCD and you can choose the discharge current (0.5A or 1A)
I regret the absence of instructions in French and this intense sound BIP happens at any time of charging and discharging, it is unpleasant.
However, it is a performance product that allows to save on the purchase of batteries, and recharge your batteries.
