OK laugh if you want I left my lights on when I arrived at work yesterday.
My alarm keyfob warned me of battery issue a few hours later and I went to investigate. Side lights dim, no juice for starting, jump started off a colleague, left both cars running for 20 odd minutes.
End of day few hours later car starts no problem, drove home (45 mins) parked in garage, thought no more of it.
This morning dead as a dodo, dash lights but not even a click when trying to start.
Jump started off daily driver (determined to drive the Supra in this weather ) went to work all electrics turned off, no AC, music etc. (Exhaust & turbos is all the music I need )
End of day dead as dodo, jump started, now home.
So Battery not holding a charge anymore, does running it down once kill it?
