Peukert's Exponent is a number which describes how battery capacity
shrinks as the rate of discharge is increased. The Link 10 uses a number
between 1.00 and 1.50 to describe how fast a particular battery will "shrink"
when a heavy load is connected. A more complete technical discussion of
the Peukert Exponent, and typical value tables is included on pages 39–41.
The Peukert Exponent set at the factory, 1.25, will be satisfactory for
many liquid cell batteries. Gel cell batteries, or liquid cells with atypical
plate structures, may require a different Peukert Exponent. To change the
Peukert Exponent, proceed as follows:
1) Press and hold the SET button for three seconds to enter SETUP
(and Advanced Functions) menu.

SELSEL
SEL appears in the display. Press SEL
and notice that the green
LED is on.
2) Press SEL again and note that the light comes on. Continue to
press the SEL button until F8 appears in the display. This will require 18
presses of the SEL button. The FUNC LED will be lit.
3) Now press and hold the SET button. The default value of 1.25 (or the
previously programed value) will appear in the display. The range of values
is from 1.0 to 1.50. Holding down the SET button will cause the display to
increment in 0.01 steps, after four increments the display scrolls faster.
When the value you want appears, release the SET button. If you over-
shoot your capacity you will have to scroll all the way to 1.50 after which
the display will roll over to 1.00 and continue incrementing. You also have
to scroll all the way through to declare exponents between 1.00 and 1.25.
4) After 10 seconds the meter exits the Setup mode and the selected
value is stored as the new Peukert's exponent and the display returns to
(Volts).
