Rechargable batteries

    I've been a visitor to green issues for about 2 months now and I wish to introduce my own pet hate.
    Yesterday our house was hit by the annual barage of battery powered toys and gadgets. I noticed that yet again many of the instruction leaflets said not to use rechargable batteries. Yet all seem to run perfectly fine on rechargables.
    Surely its time for EU law to ban this practise of discouraging use of rechargable batteries.

    Funny you should mention that, a cd/karaoke player for my niece bore that instruction - "Do not use nickel-cadmium rechargeable batteries", love to know why.

    Mike.

    Same with the Gameboy I have, "no non-alkaline batteries" it says in the manual.

    I don't know if this is the reason but rechargable batteries have a lower voltage than their old fashioned equivalents. About 1.2 volts instead of 1.5. Some electronics might not like that.

    John there is certainly truth in what you are saying, but this is a design issue. Isn't it about time the EU set a standard requiring that toys for the european market be designed to use rechargable batteries.

    This is true, however the voltage of alkaline batteries drops off as they expire. Rechargables remain at a constant 1.2V.

    The NiMh type rechargable does not suffer from memory effect and lasts longer (up to 2700 mAH) than the older NiCd type AND alkaline batteries.
