The battery backups are only good for short time and then the battery seems to expire, i took mine apart and made my own from a car battery I can run 4 mp40s for a week probably.
If its possible it doesn't hurt to get a battery powered air pump or if ou can but a small generator 1000-2000 watt
Power doesn't go out much but I bought one for the just i case days
