the lie of rapid NiMH self-discharge
"Jeff Liebermann"
NiMH cells do NOT totally discharge themselves. They discharge to
about 50% of capacity (by self-discharge) and then just sit there.
** I have several sets of AA NiMH cells - all Sanyo brand and rated at 1700
to 2500 mAH.
Self discharge is a REAL problem, but no worse than with NiCds.
In general, charged cells lose 90% of capacity in about 6 to 8 weeks -
taking a full 6 hour charge at 400mA to recover.
In my Canon A430, the uncharged cells will run the back display for a few
minutes, let me take a few shots and maybe one flash before the camera shuts
down.
