how to charge your battery without a charger?
cool air will be sucked in [reversion] and it will bend a valve.
one time over short distance under 15 miles , not big problem long term over large distances multiple Tickets, lower mpg, valve damage, burnt legs (yours)
Copper sheet 3ft x 3ft, blow torch entire surface of one side, scrape with steel wool, wipe off, solder a copper wire on each surface, put it in the sun,attach wire one to positive one to negative terminal. But went it is charged it could easily lose charge so when it is disconnect it. A charger is easier
You'll be sorry if you do. DON'T do it.
