I have a 8A Intelligent Mains Leisure Battery Charger from Rayne automotive the spec says it will charge batteries up to 140 ah. Will this charge 2 x 90ah batteries connected in parallel ?​

 
yes. . . just slowly . . (assuming its a modern smart charger capable of charging AGM/SLA batterys?)

go a pic of the charger so we can double check for you?

this one?

if so, then yes. the 8A will be slit across the two batterys , so will charge at 4A each.

very rough calculations not taking into account DoD,SoC,DutyCycle, etc etc would show around 24 hours for a full charge.

2x90ah battery = 180ah / 8ah charger = 22.5hrs


++++++++++

2x90ah battery = 180ah

180ah * 0.5(DoD) = 90ah -> / 8ah charger = 11.25
