Need to know the capacity of the batteries - the resting voltage (you mentioned 11.4 but expect (hope) that is under load - as 11.4 resting is DEAD.) - and the output capacity (amps) of the charger/converter...
The resting voltage will allow you to approximate the percent of charge needed... Can then calculate how long it will take your converter to deliver that (of course some loss due to inefficiencies...)
As example - if voltage is 12.1-12.2 - roughly 50% charged depending on the source you look at... and the total capacity is 200amps (sum of the amps of the two 12v batteries connected in parallel) - we need to add half that - or about 100 amps... A 55amp converter will take at least 2 hours to do so...
