That depends on how they are hooked up. If you just have them wired together in parallel, then yes, they will both get used together. But if you use a battery isolator switch then you can just use battery one, or battery two, or both, depending on where you manually set the position of the switch.

The answer to this specifically should be NO. The wires coming from the charger (4 instead of 2) will not connect the batteries together at all, so if one is draining, the other will not, during use. BUT, when charging, it will charge both, perhaps a little slower, but as stated in other replies, must be monitored. Just change it out for a 2 bank smart charger and you will sleep better.
