The Link 10 may support an optional two wire temperature sensor. The
temperature sensor is activated by turning Advanced Function F16 ON.
With F16 ON, F03 shows battery temperature in degrees Celsius. When
activated, F03 will continue to display temperature after exiting the Setup
mode until one of the two front panel buttons, SET or SEL, is pressed.
The limits of the temperature sensor are 0 °C (32 °F) to 99 °C (210 °F).
Versions of the Link 10 prior to Serial Number 005000 do not support this
function.
Introduction to Peukert Exponent
The Link 10 shows true amp hours consumed in the amp hour display.
However, the light bar shows how much of the available battery has been
consumed. In 1897 a scientist named Peukert demonstrated that as you
discharge a battery more quickly, its effective size temporarily decreases.
A battery is considered fully discharged when it is no longer able to main-
tain 10.5 volts under load. As you'll see in the following table showing the
effect on a typical liquid cell battery, the faster the discharge rate, the
smaller its effective capacity:
Hours to Discharge Capacity as percent of 20 hr rating
20 100%
10 84%
5 67%
2 56%
1 47%
In other words, a 100 amp-hour battery, discharged completely in one hour
will only supply 47 amp hours before dropping below 10.5 V!
