First battery in the series voltage low

It depends on the size of the charger. Due to the size of the battery, a 30A charger would be ideal. 5 hours for a 30A charger would be about right. It might take longer for a smaller charger.

I've just got the battery charger and I've charged the battery but after 24 hours of the battery being idle the voltage drops to 10.50
Does this mean the battery is dead? and if so how should I manage the bank of 16 batteries?
I cant replace it with the exact model and not even sure I can find another 280AH here.
