NiMH are definitely not recommended for this type of low current drain
application.  I suspect the lower capacity ones may not be so bad, but I
have 4 sets of high capcity AA's (raning from 2000 to 2300mAh) and I find
that they have little charge left in them after just a couple of weeks of
sitting on a shelf.  I would certainly go for alkalines made by a reputable
manufacturer in an IR remote.

FWIW I have had 1 AA NiMH cell leak, an older 1200mAh unit.

Mike
