Can we put 12v batteries in as replacements? (Is that a really stupid Q...if so, sorry)
If you connect your 6 volt batteries in series it will make the output 12 volts.
Your appliances need this 12 volt in addition to the 110 volt to operate.
Yes you could change out your 6 volt to 12 volt batteries. If you put into they would be wired parallel.
Getting your batteries correct should solve all of your problems. Even if you plug the refrigerator direct to 110, it will not work without the 12 volts also.
