Here is a chart:
"The chart above shows the amount of time it took a PD9155 (55-amp) converter set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
14.4-VOLTS (Boost Mode) – Returned the battery to 90% of full charge in approximately 3-hours. The battery reached full charge in approximately 11 hours.
13.6-VOLTS (Normal Mode) – Required 40-hours to return the battery to 90% of full charge and 78-hours to reach full charge.
13.2-VOLTS (Storage Mode) – Required 60-hours to return the battery to 90% of full charge and 100-hours to reach full charge."
It is far better to use solar imho.
Awesome. That is exactly what I was looking for. So Progressive's claim of charging a 125 AH battery to 90% in 2-3 hours was more than likely from a 0% state.
Too bad that graph isn't a little more detailed. I would love to see the different charge times for different depletion percentages.
However, at 14.4 the line does look somewhat linear at most points. Maybe past 10%?
Again, thank you. That is exactly what I was after.
But as far as solar, I would really like to go that route, but I will be parking in the shade as much as possible, thus I am not sure how effective a solar panel will be being in the woods, shaded by trees.
