The largest chargeable battery I have seen in a "D" cell was a rating
of
4,000 mAh. This would be 4 Ah. This battery type was an industrial
rated
battery primarily for running portable lighting equipment, and
communications equipment. The standard "D" cells that I see are rated
at
2,000 mAh. Maybe the battery you saw is really rated at 1,100 mAh, and
they made a printing error?

At http://www.cheapbatteries.com/nimh.htm you will see 7000 and 8000 mAh
rechargeable D cells.

The rating of 11,000 mAh for a single "D" cell sounds very high, or
this
is battery type I have not seen yet!

I would say that 11,000 isn't unheard of.

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!
