[Elecraft] Battery Charging with DC Power Supply

[Bill Miner]

<I am using an Alinco DM-330M power supply. Across the output of the <power supply I have a 26 AH battery. If the AC power quits I have <many hours to shut down the K3.
 
Charging a battery with a DC supply not meant for that purpose is a very BAD idea.
 
In the case of Astron supplies it can damage parts of the DC regulator.  If there is a "Crow Bar" circuit that operates with a battery connected to the power supply output it will ruin your day or even burn your house down!
