I’m considering a solar system to work on the road with my laptop. THe laptop is rated at 65 watts. I know 12v lead acid batteries come in many flavors, but lets just pick a more or less standard 44Ah, 720Amp battery.
How long could I expect such a battery to run my laptop? Assume I have all the correct and necessary inverter, charge controller, solar panel to charge the battery completely, etc.
I essentially would like to run my work computer off of the grid for as long as I can without recharging but don’t know if a standard car battery will suffice.
