I'd bite the bullet and buy a brand new battery, and later a new charger

He connected the battery charger leads in place of the flat battery - later he borrowed another battery and got smoke billowing from the alternator.
Brief conclusion is it seems the alternator is FUBAR and possibly taken the battery with it.

Staqndard battery for a B230 powered 740/940, choice of several there all with free next day delivery. Used that places a few times now.
As for the alternator, a decent autoelectricians should be able to diagnose the fault (probably rectifier gone short circuit) and fix it and/or supply a reconditoned unit - almost certainly a Bosch on the 740 which i'm fairly sure Matts car is.
