USING YOUR LINK 20
STATUS LIGHTS
These green lights tell you
what units are displayed.
Volts is the electric potential to do work. Voltage is useful to
assess the approximate state-of-charge and to check for proper
charging. Examples: An at rest, fully charged battery will
show about 12.8V. A 20 hour rated battery is 100% discharged
when it reachs 10.5Volts with a 20 hr. rated load applied.
Typical charging voltages may range from 12.9 to 14.9 Volts.
Amps is the present flow of current into (or out of) the bat-
tery. For example, a refrigerator may draw 6 Amps of current.
This is displayed as - 6.0 (6 Amps are being consumed
from the battery). Discharge is shown as a negative number.
Charging is shown as a positive (unsigned) number.
Amp-hours (A hrs) consumed represents the amount of en-
ergy removed from the battery. When a 10 Amp load is on
for one hour, 10 Amp-hours are consumed. If you started this
discharge with a full battery, your Link 20 will show -I0 in
the
display. During charging the Link 20 compensates
for charging inefficiency and counts back up toward 0.
Time is an estimate of how many hours the battery will sus-
tain a load before it reaches a settable discharge floor. The
estimate may be based on the instantaneous load or averaged.
Four minute load averaging is the default. During charging
the Time display reads CCC , indicating the battery is charg-
ing. When charging, Amps is a positive number).
For the TIME function to operate correctly, you must correctly enter your battery
capacity, type, and check that an appropriate Peukert Exponent has been selected through
the SET UP routines.
