RE: MD: Re: Additional Battery
But there's only so much current a particular chemistry can handle putting out before it dies a premature death. A perfect example of this was Makita power tools which were released with NiMH batteries. Their battery packs died within 3 months of usage and so they were recalled and replaced with NiCd's like they used to use without any ill effect thereafter. Proof in the pudding is in the tasting.

If a power supply can provide 3.5 amps, but the equipment only draws 500 mA, then that's what it will get. The only time I can think of that something else would happen would require a malfunction/short circuit within the equipment itself, but that is still not a battery or power supply problem. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

Is this a bogus > argument? It may be partly true: as far as I know, NiCd batteries (don't know about NiMH) will produce a very high current when short circuited, or with a resistance of less than one ohm across them, but most electronic equipment has much higher resistances (eg 100 ohms) so this should not be a problem. I also heard somewhere that Li-Ion batteries can be ruined by shorting their terminals, due to a buildup of pressure that can't be vented quickly enough, although I'm not sure if this is true or not.
