1) 100%
2) Enough to know it isn't charged so I refer to my kWh meter
3)31C
4)You'll find that in the Lifeline PDF manual. Voltage versus charge percentage is a farce. Voltage calculated with amperage acceptance is not a farce.
5) I've never looked for the MegaWatt power factor spec because it does not concern me. I'm sure John Marles at Megawatt knows that information. Size the genset for inrush rather than search for a non existent inexpensive power factor corrected power supply. The precise adjustment from 10 volts upward makes PF correction less of an issue.
