Cycle Status
The cycle status is composed of a
number of 'bit fields'. Each bit field has a number and a
condition attached to it.
1
=
Discharge cycle
2 = Recondition discharge cycle
4
=
Charge
5
=
Trickle charge
16 = Battery passed
32
=
Program completed
64 = Rest cycle
128
=
Program interrupted (due to of battery, over
temperature or full load)
256
=
Plateau timeout (charge)
512 = Negative slope (charge)
If a certain condition exists, the number presenting that
condition becomes the cycle status number. If more
than one condition exists, the numbers are added
together and the result becomes the cycle status.
Example
If the unit has successfully completed a
charge program, the fields for: program completed (32),
program passed (16) and trickle charge (8) form a set,
giving a result of
32
+
16
+
8 = 56.
Fields
4,
5,
6
Program Duration
in hours, minutes and system
seconds respectively.
Note
The program duration may be off by as much as
1 minute due to errors caused when synchronizing with
the rest of the system.
Field

Average Cell Voltage
To derive the actual battery
voltage, multiply the number of cells by 1.25V (or 1.20V
depending on assumed cell voltage) for NiCd or 2.00V
for Lead Acid batteries.
Note
Some battery manufacturers rate NiCd and NiMH
batteries at 1.20V rather than 1.25V per cell. This
discrepancy
results in a different battery terminal
voltage, but does not affect the battery results as the
nominal cell voltage of a NiCd is an arbitrary assumed
value .
