Yes, some of the MSR-2000 power supplies also have battery
type selection mode (switching).

I want to thank all that helped guide me to Motorola TPN1105/TPN1106
schematics, back in July 2007.
Although, these above schematics are not the Motorola Micor power supply,
that I have. They are similar.

The question is... what are we trying to do with the end result?
Switch off a device after x-time of non use and/or protect a
battery bank from discharge?
Most newer Kenwood Radios I sell have non-use power off timers

The power gate is a cute but expensive box... You should be able

The problem with the PWRGate and all the answer/reply posts I've
seen so far is so far there no mention of a low battery voltage
disconnect circuit.
Mark,
There have been some good suggestions. However, there are two issues
that you need to watch carefully for remote battery backup operation.
The first, as some have mentioned, is the charge current if the
battery is run down and AC power comes back.
For example, if you just tie a battery
