I cannot comment on the K1 but for the past two years we have powered 
our K2 in RSGB NFD off 4AH Gel Cells. Running at 5W output one gel 
cell will easily power the rig for well in excess of 6 hours We used 
2 of these cells to cover our 12 hours of operating time and they 
were far from flat at the end. The only reason we swapped cells 
halfway through was to get rid of the annoying 'Lo Batt' beep which 
is a little too conservative with its threshold level. The K1 should 
last quite a lot longer.

Incidentally GW4ALG entered the Battery Management Challenge in last 
year's NFD using 8 AA alkaline cells and operated for around 6 hours 
at 1W level - he had to give up when it became too dark to see, while 
there was still plenty of life in the batteries!

This year in NFD we used 7AH cells at the 10W level with the same 
experience - see http://www.g4bra.org.uk/nfd04.htm.
