Having driven vehicles and used equipment with dual batteries, this is my experience.
If they are 2 12V batteries in parallel, I have found it best to charge them separately. I have found that often times one battery will be holding less than a full charge while the other battery is holding a full charge.
By charging them separately, you can be assured that both batteries are fully charged.
My thinking and understanding is that when one of the batteries reaches full charge the battery charger (or voltage regulator) will sense that the full battery voltage is reached and will stop charging.
Even though both batteries may be the same size and capacity, they will not have exactly the same charge/discharge rates and curves.
I know from experience that the p/u's I drive with dual batteries, I have obtained a longer battery life by once a year cleaning terminals, washing the battery outside and battery box with baking soda and charging each battery separately.
If it is 2 12V batteries in series, use either a 12V battery on each battery or a 24V battery charger. I am not sure, but I don't think hooking up 2 12V battery chargers to make a 24V battery charger would be a good idea.
