Battery Testing
Five kinds of testing
1: Open-Circuit Voltage
Open circuit means no current in, no current out
Battery switch to OFF
Battery charger not sending any current (shore-power disconnected?)
Anything directly wired to battery (eg, bilge pump) disconnected
Important to let the battery "rest" (become stable)
Nominally 24 hours, in practice 2 hours is probably...
