In the morning, I arrive at Ceduna to refuel, wash my car, and shop for a new (less powerful) inverter – along with many, many spare gas bottles
, of course. However, it looks like it's a little too late by now, because the more I look at the battery, the more it appears to be the source of the problem. It doesn't hold any charge at all, and drops to 11-odd volts almost as soon as I unplug the solar. Looks like it's time to ditch the sucker... but it's too difficult to find a decent deep cycle battery in these parts, so I need to drive further to try my luck elsewhere. In Adelaide, perhaps?
