we have rechargeable batteries in the remotes for the tv and stereo, digital camera and DD's ipod( she bought it herself).
we just plug them in overnight and they are good to go in the morning when we need them.
yes the eare a bit $$$ ( here in canada anyway) but it saves buying disposable ones and putting them in the garbage. and we have a store here that once your rechargables have finally bit the dust will take them to dispose of them properly and give you a $5 voucher off the price of new ones too.
