label "CH" for charged and "DISCH" for discharged value over the unit "mAh". Also the

current is changing depending on the chosen current during the Charge Test. The used

charging current is symbolized by „CH-CURRENT" as well as the discharging current by

„DISCH-CURRENT".

Generally, the charging capacity value can be different to the discharging capacity value

because of efficiency of the chemical reaction in the batteries.

This mode can also be used very well for refreshing batteries.

Discharge Test

The difference of „Discharge Test" program to „Charge Test" program is, that the batteries

will get charged in the 1

step. The process is as follows:

1) Charge (This capacity gets measured and displayed but not stored till the end)

2) Discharge (The capacity gets measured and stored and is available after end of the

test)

3) Charge (The capacity gets measured and stored and is also available after end of the

test)

The measured capacities can be, as well as in the "Charge Test", retrieved by pressing the

channel button. If a high charging current is chosen, it can happen in some cases that the full

charging capacity is not reached (this depends on the quality and condition of the battery).

A lower charging current is able to put more energy into the battery but therefore the

procedure lasts longer. The procedure to see the chosen currents and the measured

capacities is the same as for "Charge Test". This is the best way to measure the current state

of health of the battery (still available capacity of the cell).

At "Charge Test" and "Discharge Test" the discharging current will be selected automatically

to 500 mAh. The table below shows the selectable charging current values followed by its

discharging current.
