Best type of batteries for the following devices

[QueHuong]

Rechargeable alkaline (ex. Rayovac Renewals) vs. NiMH:

1) MP3-CD Player
2) Palm
3) Lego Mindstorms RCX
4) TI-83+
5) TV remote control
6) MP3 Player (not the CD player)

1. NiMH
2. Dunno
3. Dunno
4. Don't go rechargeable.
5. Don't go rechargeable.
6. NiMH

I say don't go rechargeable on the two because they are such low drain I don't think it's worth it.

Thanks, Sukhoi.

Does anyone know about the #2 and #3?

I've heard of "going #1" and "going #2", but "going #3" is a new one on me. 😉

2) I've had good luck with quality NiMH in my Visor.
3) NiMH good here, too. The voltage is lower than alkaline, but they're capable of cranking a little more juice, so it kinda balances out. I usually use external power when possible.
4) Used NiCd and NiMH in my overclocked TI-92 😎, just dandy.
5) Rechargables not worth the trouble, alkalines last for friggin' ever.

On my TI-89 a set of four Duracell Ultras lasts me over a year. But then somebody told me that the Ultras are only better on high-drain devices and would actually be worse in a calculator. I have no idea if they knew what they were talking about or not.

I'm still on my original set of alkalines for my TI-89, which I put in there in the fall of 2001. :Q

When I was using alkalines for my Palm IIIxe, however, I noticed that the Ultras had a significantly lower lifespan than the regulars. But maybe if I had one of those fancy new color PDAs and not an old school Palm the Ultras would be better.
