The lights illuminate when the test switch is operated.
The lights do not illuminate when power to the entire installation is lost, ie. a power cut.
That is not likely to be caused by the lights being fed from a different circuit.
My guess would be that the test switch is incorrectly wired so that it is connected to the switched live terminal thus switching the light on rather than simulating a power failure.
If this is the case then it probably doesn't have an unswitched supply at all and so the battery hasn't been charged.
