Answer by Poncho Rio
First off, a battery is a DC power supply.

As constant current, it is probably not good since the voltage of the battery will decrease over time.

You may want to use a battery as a backup and use a rectifier as your main source.

You will probably want to get a rechargable battery also.

You will probably use a switch to cut in the battery when power interupts.

You should be able to do this with solid state as well.
