Is it OK to mix battery types??

After we had had our mh for a couple of years, that only had one battery, I wanted to add a second battery. So I added a double throw switch, which allowed me to use only battery at a time and switched them every day. But paralleled them while driving to charge them. That kept them rather equally charged, and worked fine.
