Application
Recondition Discharge is a slow deep discharge applied
below the end-of-discharge voltage threshold. During
this gradual depletion of the remaining energy, the
crystalline build-up (memory) on the cell plates
dissolves and the NiCd battery is commonly
restored.
Definition The set figure in Table 11.6 is a percentage
of the battery current rating (at one volt per cell).
Speed and safety The best compromise between
speed, effectiveness and safety is a Recondition
Discharge of 12%. This setting is small enough to avoid
damage if cell reversal occurs and is large enough to
achieve a reasonable short Recondition
Discharge time.
The Recondition Discharge current decreases with the
cell voltage (simulating resistive load).
If the Recondition Discharge is set too high, the LCD
indicates "TOO HIGH". The C-Code is invalid.
Recondition Discharge is applied to the NiCd and NiMH
battery families only.
