Just for chagrins, why use a diode?
I simply float the battery across the bus.
No diodes, no relays, no problems :)
At home, I set things up a bit differently, I use a much smaller
power supply since it has a lot more time to refill the battery.
Essentially any supply that has non "foldback" current limiting,
works nicely. The right supply has a current limit, and it will
output that current into a battery or a dead short, 24/7. The
foldback units are kind of useless for battery floating, when you hit
a limit, they drop their output current to some much lower level,
until the load goes away entirely.
Switchers work nicely too, but some have no real current limiting,
which is a bad thing.
