I just worry that the voltage of these is a bit too high, if the device takes 3 or 4 in series. They tend to be around 1.8 volts per cell, significantly higher than a fresh alkaline AA at around 1.6 volts, and even after half the energy is discharged, if the device is off for a long while, the initial voltage for next turn-on creeps all the way back up.
(The price doesn't bother me ... it's worth the much lower chance of leaking than alkaline, if you leave it in a remote or gadget for years. But I've come to think that rechargeable NiMH like eneloops are a better idea due to the voltage.)
