Never mix battery types, stay red-red, yellow-yellow. They have different characteristics between them and will work against each other in chemistry ways.

You'll also hear battery people say you have to put new batteries in at the same time because an old battery will make a newer one fail more quickly.
But this is all true if you hook them in parallel, not using a battery isolator that separates the batteries. The isolator setup is the key.
