[Elecraft] Field Day Battery Capacity

[Stuart Rohre]

I am pretty sure we had a similar jump start battery and it did not last 24
hours.

That of course depends on the rig you are running and its receive and
transmit current drain.  A Ten Tec Scout takes more current to deliver 5
watts than an Elecraft K2 does for example.

We have used 45 amp hour 12 batteries for various 5 watt level operation of
rigs such as Kenwood TS 130, and 140, TT Scout, K2, 817, etc.  Also used
deep Cycle Marine batteries for whole 24 hours, while usually swapped out
the 45 amp hour types to not take them down too far.  We have seen them stay
up pretty well on active band like 20m coming down from 13 to 12.6 volts in
24 hours.
