DCHOnly (Discharge Only)
Function:
The DCHOnly program determines the residual capacity of a battery,
prepares batteries for storage and checks battery performance under load.
To determine battery capacity, fully charge the battery using the
Charge
program
before running the
Discharge only
program.
Sequence:
The battery is discharged until its voltage reaches the E
ND
-O
F
-
D
ISCHARGE
setting in the C-code.
Results:
Detailed display shows battery capacity as a percentage of
manufacturer’s stated capacity for the battery model. It also shows average battery
or cell voltage, analyzer charge or discharge current (in mA), battery temperature
and duration of service. Look for the green ready LED. The battery capacity is
measured during a discharge and if the battery is partially discharged, the capacity
may be lower than the target capacity. This may give a Fail Code 115 or 116. The
battery is not necessarily poor.
Duration:
Approximately 1 hour for a NiCd battery discharged at default C-code
settings.
To edit the Discharge Only settings
The Discharge Only test settings cannot be edited. However, the program uses the

).
Smart batteries (often used in laptops) should not be stored in
a fully discharged state. If the battery’s voltage drops below
the level required by the processor within the battery,
information can be lost. In some cases, this data loss can
leave the battery permanently unusable.
