[Elecraft] K3/100 - Battery - A&A Engineering 5 Amp Smart Charger

[Don Wilhelm]

Paul,

That is correct, the A&A Smartcharger may become a light load (175uA) 
when off, but I see no reason to ever turn it off if you have a battery 
connected to it.

A word of caution about batteries - while the gel cells can be safely 
used in an unvented area, a deep discharge battery (or any other 'wet 
cell' SLA) will outgas hydrogen during charging, which can create an 
explosion hazard.  Please put the battery in it own separate area 
isolated from your operating, working and living area and adequately 
vented to the outside air.  RV stores sell battery boxes that are sealed 
and have a vent tube if you need to keep the battery in the shack/living 
area.  Be Safe!

73,
