Harry,
You're right.
Most battery monitors for recreational boats are NET charge monitors. They monitor the balance of what goes out to what comes it.
It's not a leap to figure out what you USE. That's so easy it's child's play. It's what goes back IN, based on battery acceptance, that most people don't get.
Hence, using a net monitor works for most folks.
