I used my K2/100 with an 80 ahr deep-discharge marine battery over field 
day weekend and it worked out well - left the rig running all weekend, 
made 350 or so CW QSOs, and voltage was down to 11.2 by the end of the 
weekend so it would have gone a while longer.  I used that battery 
because I happened to have an extra one - it's sitting inside a plastic 
Wal-Mart battery box, but because it's in the house I'm going to swap it out for 
an AGM battery - no fumes, no maintenance, no way to spill acid.
