If you plan to use a lead-acid battery again, you should be able to restore the working inverter. Because I use readily-available alkaline 'D' cells in my inverter, much greater efficiency is needed, one reason why I strongly suggest that anyone making the device should stick closely to the recommended parts list.
It would be interesting to see your circuit, Refugee, for comparison; I did mess about for some time with the component values in a standard multivibrator circuit but got nowhere. It is always possible that further experimentation might have yielded the requisite efficiency but at my age the brain gets tired and I ended up going in ever-decreasing circles!
