At 50mA that would be less than the self discharge rate of a lead acid

Not so. A lead acid in good condition has a very low self discharge
rate.


More than a 1,000 hours?


Yes.

A pal has a place in Spain. In better days goes there for at least 2
months at a time, leaving a car here. With the battery left connected,
totally flat on return. And toast. Disconnected, it will start the car
after re-connecting.
