Questions.

1. I've found online a NiMH D-Cell boasting 11,000 mAh for $9. Can that be
true?

2. The few Li-ion in D-Cell config I've found have pathetic milli amp hours.
Are there any that will last a long time in something like, oh, a baby swing
and/or flashlite?

3. I know that the unused shelf-life of NiMH and cads are pretty bad. But
what of the lithiums? This is important because I'm interested in
flashlight usages too.

Are there any good pointers to D-Cell rechargables (not the old zincs or
lead-acid's)?

Inteded uses:

Baby swing
Flashlights
Radio

4. I know that a regular D-cell (and others) are 1.5 V. Is there a "under
load" consideration that changes specifications for that? What are the amps
of such things. I understand the concepts of volts, amps, amphours, etc.,
but do not understand them as they relate to batteries. Furthermore I've
read that the rechargables typically don't quite reach the 1.5 voltage.


Thanks!

I haven't seen any 11,000 mAh NiMh batteries, but I have seen
8,000 mAh 'D' cells for 9 or 10 dollars.

A standard 'D' alkaline cell will be about 16,000 mAh and
has a long shelf life. Alkalines are probably better for
the radio if you don't play it all day long. Same goes
for the flashlight if you don't use it much.

I hear recharable Lithium cells have a very long shelf life
(charged) but they may blow up if overcharged. I think the
capacity is about the same as ni-cads.
