delivered over the course of a number of hours.
For example, the ProMariner ProTournament 300 Quad lists a charge rate
of 300 amps in 10 hours.
I don't know if that is a limitation or just an indicator of current
flow capacity. I mean 30 A over ten hours gives 300A that can be put
back in to a battery bank. But can it give 330A over 11 hours or will it
"go dumb", believing there to be some battery issue...
What if someone wants to charge an 80% depleted bank of 4 220Ah
batteries, meaning a total of 700Amps to be put back in. Could this
charger do it over the 23.47 hours it would take at 30A or would it
throw a fault of some kind after 10 hours at 30A?
Food for thought.

I would guess the "time-out" time period would be information the charger manufacturer should have. Knowing that you should be able to cycle through off/on regularly and have no interruption in power. Right?

>> I believe Jason is right about the battery chargers "going dumb" on occassion. I was doing some extended motoring using my ZIVAN NG-1 and running it flat out with the Honda 2000 providing power. At the time I did not have a functioning current meter so I was cruising along when several hours later I began to notice that the battery bank voltage was dropping but, the Zivan charger still had a green light. So I kept moving along. When the battery bank voltage hit 48 volts I figured there was some kind of problem. I disconnected the Zivan from the Honda generator and reconnected it and the charger started to charge again (red light = bulk charge). If I had a functioning current meter I would have noticed that the battery charger had gone into a fault mode much sooner and reset of the charger earlier which would have prevented the increased draw down of the battery bank. I have since been able to repair the defective current meter
