Fred,

If I understand properly, you still have the float battery connected.  Try
removing it and see if the power supply turns on.

If that power supply has undervoltage protection, a discharged battery
across its terminals  will create an undervoltage situation and the power
supply will shut down immediately.  If that is the case, charge the battery
from another supply before re-connecting it.

I do hope your gel cell recovers, especially if it is a costly large one,
but there is a chance that the low terminal voltage has significantly
reduced its life and charge capacity.

73,
