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 12.8 V. A 20-hour rated battery is 100% discharged when it reaches 10.5 volts with a 20-hour 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 battery. 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 (Ah) consumed represents the amount of energy 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 -I0in 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 sustain 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 5 the SET UP routines.
