Running very low level devices like phono stages off batteries makes sense. Channel D does this with several of their phono stages including the $60,000 Seta L20. The AC charger is switched off during operation.
Otherwise, there is no significant benefit worth the expense. We have excellent power supplies.
In theory since a really big battery is a really big capacitor you could build a very powerful amplifier around one. I am no expert in this but it seems that the cost and size of such an amplifier are prohibitive as nobody seems to want to make it.
