    A bit off topic I know but:

    I know that Ni-Mh batteries are better for high-drain equipment, like our digital cameras, but does this go for all battery-powered equipment?

    I want to get more "eco-friendly" and replace the alkaline batteries (as they wear out) in the low-drain appliances round the house (clocks, remotes, etc). Can anyone comment whether the power characteristics of NI-Mh or NiCad are better for this type of device, or is there no real difference?

    If "eco friendly" is your motive then toxic Cadmium might be best avoided!
    Ni-Mh are your best bet. They have no memory effect so you can charge them when you feel like it. 2 points to bare in mind - the terminal voltage is 1.2V for rechargeables (alkaline etc are 1.5V) though most devices won't have a problem, and Ni-Mh do self discharge though it will be some months before they go flat sitting on a shelf (or inside a clock)

    Avoid NiCd. The 'memory effect' makes them unsuitable for any electronics where the battery is not fully discharged prior to the appliance cutting out. NiMH does not suffer this problem.
