If the Link 1000 is correctly installed the battery
voltage is measured directly at the battery
terminals and, therefore, the Volts displayed is true and accurate.
The Link 1000 is not affected by battery type. One should, however, investigate a reasonable choice for Peukert exponent (use 1.1 or 1.2 for good AGM
batteries). Investigate good choices for "charged parameters" whereby the Link 1000 shows a charged battery and resets the Amp-hours and kilo-Watt-hours to zero for the next cycle. This is not highly critical if you merely wish to accept the factory default values. You may choose to display kilo-Watt-hours if you are a true energy kinda person.
