John,

Good point - but D cells still have a lot more capacity (watt-hours) than the alternatives. In low-current applications I think they are the most economical in relatively small quantities. We buy AA by the case at home, but no other sizes in that quantity, so I'm not sure about the overall economics in case and larger quantities.

I standardized on AA as much as practical a long time ago, (OK - except for ARCs and some 123 torches) but it doesn't hurt to sustain good D cell equipment that folks already have at home. OTOH, I DID get rid of C cell stuff a few years ago and don't miss them. I have a couple of D mags that I haven't converted to LEDs yet - probably will never get around to it, as I just use the already converted ones.

Just my opinion: The most versitile "scrounger" device is something designed for 1 - 2 D cells and a set of battery adapters for it to allow AAA AA and C cells to be used.

I scanned thru Tom's shootout back when he posted it - it was better reading this time, in this context, and I paid a little closer attention to the details. Thanks for reminding me and posting the link to it!

Regards,

Tom
