My solution is similar. I use a sealed 12 AH gelcell 'jumpstart' battery with a built in charger (paid $50 at AutoZone, but seen for as low as $40).
Here's a link to the Mity Mite: http://www.batterychargers.com/details.cfm?prodid=PS%2D120A&catid=13 I leave it plugged into the outlet all of the time (float charge ... takes a few days to top it off if I've drained it significantly). Sometimes I'll unplug it to see if I'm getting much RFI from the charger - but it is usually very little. I went with a 12 AH because it should be more than enough for me to use for Field Day each year with my K2/QRP. Daniel AA0NI p.s. No Hydrogen problem with this set up (that I am aware of). p.p.s. I keep this in the bedroom underneath the student desk by the window I operate from. If it was a real car battery or deep cycle battery - I'd probably keep it outside, and run the power through the window/wall to avoid Hydrogen because it can be a serious danger - even with a trickle charger. --- " \"RC\" KC5WA" <[EMAIL PROTECTED]> wrote: > A Word of caution Charging Car Batteries give off HYDROGEN GAS don't > charge them indoors in a closed room > > Dan Barker wrote: > > >I just gave up on the whole thing, bought a car battery and a $20 trickle > >charger.
