Hi John,
NIMH batteries will self discharge in 30-60 days. This is consistent
with your experience and mine as well. My wife uses AA cells in her battery
hungry HP camera and always recharges all of her sets prior to using her
camera.
Being here in Australia, avoid Dick Smiths Digitor batteries.
Cheers,
Bob
