if there are 2 batteries connected in parallel, they will charge each other until they are the same voltage in each battery.
when hooking up batteries together like this for say an off grid solar set up, it's best to get matching batteries that are the same age. I assume the same holds true in a vehicle. this helps avoid that as they charge at the same rate and deplete at the same rate. I have never dealt with a vehicle with 2 batteries though.
