Hi John!
Thanks for the extra info. I've never come across this particular method
of measuring battery/power before; all grist to the mill.
As yet I haven't had the chance to use the FR-2LE enough to find what my
particular usage will be. The weather here in England has been
particularly hot and humid for the last week or so. This doesn't suit
one of my health problems, and so I haven't been out much. What I'm
thinking at this point in time is, that I will keep the Tamiya charged
ready as a back-up in the car, and only probably use it, if I'm setting
up an all night recording session. If I find I can get away with AA's I
will; I'm too old to get into weight training!
Cheers
Max
