I agree with Resist's opinion that it sounds as though there isn't much chance to recharge the batteries.
Two points though:- if your 12V battery is failing then the IMA system will divert power to the 12V to try and keep it charged. How old is your 12V?
It may also be worth doing an IMA reset (disconnect the 12V battery for at least 5 seconds to clear down the memory) which may shake things up a bit for the better. HTH.
