C8000 Battery Testing System User Manual

Sequence:
The battery is first cycled (charged and then discharged) to
determine its true capacity. If NiCD and NiMH batteries do not meet
the target capacity at the end of the discharge cycle, they are
reconditioned to reduce battery memory. Following recondition, the
battery is cycled again to determine the recovered or final capacity.
The battery is fully charged when the program completes. SLA and
Li-ion batteries are cycled once. If the target capacity is not reached in
the first cycle, it is cycled again. Recondition is not performed for Li-
ion and SLA batteries.
Duration:
Approximately 2.5 to 10 hours for NiCD and NiMH, 20 to
40 hours for SLA and 6 to 20 hours for Li-ion using default C-Codes.
Charge
Function:
Fast charge a battery.
Sequence:
A charge cycle is applied to the battery. No capacity
readings are taken (capacity is only obtained if there is a discharge
cycle).
Charge does not perform a full analysis; use the Auto or Prime
program to fully diagnose a battery.
Duration:
Approximately 1.5 hours for NiCD and NiMH, 10 hours
for SLA, and 4 hours for Li-ion using default C-Codes.
Prime
Function:
Prepares new or stored batteries for use. A new or stored
battery may require several charge/discharge cycles to form the cells
to achieve peak performance.
Sequence:
The program cycles (discharges and charges) the battery
until the difference between capacities from one cycle to the next is
less than 5%. Up to four cycles if the 5% capacity difference is not
reached. This allows for batteries that cannot accept a full charge on
the first cycle. If the battery is fully discharged, the program starts
with a charge. No reconditioning is applied. Some batteries may
require several Prime cycles to fully form the cells.
Duration:
Approximately 5 to 10 hours for NiCD and NiMH, from 40
to 80 hours for SLA, from 12 to 25 hours for Li-ion using default C-
Codes.
SelfDchg
(Self
Discharge)
Function
: Identifies the self-discharge or the amount of charge a
battery loses if it is left alone for a period of time. The standard time is
24 hours.
Sequence:
The battery is discharged for 10-minutes before charged
and discharged to obtain its first capacity. The battery is then charged
and left for a 24-hour rest period. During this time, the battery loses
energy through self-discharge. After 24 hours, the battery is
discharged to determine the second capacity. The difference between
the second and first capacity is the self-discharge rate.
Duration:
Approximately 30 hours for a NiCD battery using default
C-Codes.
